## CMake Compatibility
### Submodule Compatibility Issues
YAZE includes several submodules (abseil-cpp, SDL) that may have CMake compatibility issues. The project automatically handles these with:
**Automatic Policy Management:**
- `CMAKE_POLICY_VERSION_MINIMUM=3.5` (handles SDL requirements)
- `CMAKE_POLICY_VERSION_MAXIMUM=3.28` (prevents future issues)
- `CMAKE_WARN_DEPRECATED=OFF` (suppresses submodule warnings)
- `ABSL_PROPAGATE_CXX_STD=ON` (handles Abseil C++ standard propagation)
- `THREADS_PREFER_PTHREAD_FLAG=OFF` (fixes Windows pthread issues)
**Manual Configuration (if needed):**
```bash
cmake -B build \
-DCMAKE_POLICY_VERSION_MINIMUM=3.5 \
-DCMAKE_POLICY_VERSION_MAXIMUM=3.28 \
-DCMAKE_WARN_DEPRECATED=OFF \
-DABSL_PROPAGATE_CXX_STD=ON \
-DTHREADS_PREFER_PTHREAD_FLAG=OFF \
-DCMAKE_BUILD_TYPE=Debug
```
## CI/CD and Release Builds
### GitHub Actions Workflows
The project includes three release workflows with different levels of complexity:
- **`release-simplified.yml`**: Fast, basic release builds
- **`release.yml`**: Standard release builds with fallback mechanisms
- **`release-complex.yml`**: Comprehensive release builds with multiple fallback strategies
### vcpkg Fallback Mechanisms
All Windows CI/CD builds include automatic fallback mechanisms:
**When vcpkg succeeds:**
- Full build with all dependencies (zlib, libpng, SDL2)
- Complete feature set available
**When vcpkg fails (network issues):**
- Automatic fallback to minimal build configuration
- Uses source-built dependencies (Abseil, etc.)
- Still produces functional executables
### Supported Architectures
**Windows:**
- x64 (64-bit) - Primary target for modern systems
- ARM64 - For ARM-based Windows devices (Surface Pro X, etc.)
**macOS:**
- Universal binary (Apple Silicon + Intel)
**Linux:**
- x64 (64-bit)
## Troubleshooting
### Windows CMake Issues
**CMake Not Found:**
```powershell
# Run the setup script
.\scripts\setup-windows-dev.ps1
# Or install manually via Chocolatey
choco install cmake
```
**Submodule Compatibility Errors:**
```powershell
# Test CMake configuration
.\scripts\test-cmake-config.ps1
# Clean build with compatibility flags
Remove-Item -Recurse -Force build
cmake -B build -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DCMAKE_WARN_DEPRECATED=OFF
```
**Visual Studio Project Issues:**
```powershell
# Regenerate project files
.\scripts\generate-vs-projects.ps1
# Clean and rebuild
Remove-Item -Recurse -Force build
cmake --preset windows-debug
```
### vcpkg Issues
**Dependencies Not Installing:**
```cmd
# Check vcpkg installation
vcpkg version
# Reinstall dependencies
vcpkg install --triplet x64-windows zlib libpng sdl2
# Check installed packages
vcpkg list
```
**Network/Download Failures:**
- The CI/CD workflows automatically fall back to minimal builds
- For local development, ensure stable internet connection
- If vcpkg consistently fails, use minimal build mode:
```bash
cmake -B build -DYAZE_MINIMAL_BUILD=ON
```
**Visual Studio Integration:**
```cmd
# Re-integrate vcpkg
cd C:\vcpkg
.\vcpkg.exe integrate install
```
**ZLIB or Other Dependencies Not Found:**
```bash
# Regenerate project files with proper vcpkg integration
python scripts/generate-vs-projects.py
# Ensure vcpkg is properly set up
.\scripts\setup-windows-dev.ps1
```
### Architecture Errors (macOS)
```bash
# Clean and use ARM64-only preset
rm -rf build
cmake --preset debug # Uses arm64 only
```
### Missing Headers (Language Server)
```bash
# Regenerate compile commands
cmake --preset debug
cp build/compile_commands.json .
# Restart VS Code
```
### CI Build Failures
Use minimal build configuration that matches CI:
```bash
cmake -B build -DYAZE_MINIMAL_BUILD=ON -DYAZE_ENABLE_UI_TESTS=OFF
cmake --build build
```
### Common Error Solutions
**"CMake Deprecation Warning" from submodules:**
- This is automatically handled by the project's CMake configuration
- If you see these warnings, they can be safely ignored
**"pthread_create not found" on Windows:**
- The project automatically sets `THREADS_PREFER_PTHREAD_FLAG=OFF`
- This is normal for Windows builds
**"Abseil C++ std propagation" warnings:**
- Automatically handled with `ABSL_PROPAGATE_CXX_STD=ON`
- Ensures proper C++ standard handling
**Visual Studio "file not found" errors:**
- Run `python scripts/generate-vs-projects.py` to regenerate project files
- Ensure CMake configuration completed successfully first
**CI/CD Build Failures:**
- Check if vcpkg download failed (network issues)
- The workflows automatically fall back to minimal builds
- For persistent issues, check the workflow logs for specific error messages

# Asar 65816 Assembler Integration
Complete cross-platform ROM patching with assembly code support, symbol extraction, and validation.
## Quick Examples
### Command Line
```bash
# Apply assembly patch to ROM
z3ed asar my_patch.asm --rom=zelda3.sfc
# Extract symbols without patching
z3ed extract my_patch.asm
# Validate assembly syntax
z3ed validate my_patch.asm
```
### C++ API
```cpp
#include "app/core/asar_wrapper.h"
yaze::app::core::AsarWrapper wrapper;
wrapper.Initialize();
// Apply patch to ROM
auto result = wrapper.ApplyPatch("patch.asm", rom_data);
if (result.ok() && result->success) {
for (const auto& symbol : result->symbols) {
std::cout << symbol.name << " @ $" << std::hex << symbol.address << std::endl;
}
}
```
## Assembly Patch Examples
### Basic Hook
```assembly
org $008000
custom_hook:
sei ; Disable interrupts
rep #$30 ; 16-bit A and X/Y
; Your custom code
lda #$1234
sta $7E0000
rts
custom_data:
db "YAZE", $00
dw $1234, $5678
```
### Advanced Features
```assembly
!player_health = $7EF36C
!custom_ram = $7E2000
macro save_context()
pha : phx : phy
endmacro
org $008000
advanced_hook:
%save_context()
sep #$20
lda #$A0 ; Full health
sta !player_health
%save_context()
rtl
```
## API Reference
### AsarWrapper Class
```cpp
class AsarWrapper {
public:
absl::Status Initialize();
absl::StatusOr<AsarPatchResult> ApplyPatch(
const std::string& patch_path,
std::vector<uint8_t>& rom_data);
absl::StatusOr<std::vector<AsarSymbol>> ExtractSymbols(
const std::string& asm_path);
absl::Status ValidateAssembly(const std::string& asm_path);
};
```
### Data Structures
```cpp
struct AsarSymbol {
std::string name; // Symbol name
uint32_t address; // Memory address
std::string opcode; // Associated opcode
std::string file; // Source file
int line; // Line number
};
struct AsarPatchResult {
bool success; // Whether patch succeeded
std::vector<std::string> errors; // Error messages
std::vector<AsarSymbol> symbols; // Extracted symbols
uint32_t rom_size; // Final ROM size
};
```
## Testing
### ROM-Dependent Tests
```cpp
YAZE_ROM_TEST(AsarIntegration, RealRomPatching) {
auto rom_data = TestRomManager::LoadTestRom();
AsarWrapper wrapper;
wrapper.Initialize();
auto result = wrapper.ApplyPatch("test.asm", rom_data);
EXPECT_TRUE(result.ok());
}
```
ROM tests are automatically skipped in CI with `--label-exclude ROM_DEPENDENT`.
## Error Handling
| Error | Cause | Solution |
|-------|-------|----------|
| `Unknown command` | Invalid opcode | Check 65816 instruction reference |
| `Label not found` | Undefined label | Define the label or check spelling |
| `Invalid hex value` | Bad hex format | Use `$1234` format |
| `Buffer too small` | ROM needs expansion | Check if ROM needs to be larger |
## Development Workflow
1. **Write assembly patch**
2. **Validate syntax**: `z3ed validate patch.asm`
3. **Extract symbols**: `z3ed extract patch.asm`
4. **Apply to test ROM**: `z3ed asar patch.asm --rom=test.sfc`
5. **Test in emulator**

} zelda3_message;
```
## Error Handling
### Status Codes
```c
typedef enum yaze_status {
YAZE_OK = 0, // Success
YAZE_ERROR_UNKNOWN = -1, // Unknown error
YAZE_ERROR_INVALID_ARG = 1, // Invalid argument
YAZE_ERROR_FILE_NOT_FOUND = 2, // File not found
YAZE_ERROR_MEMORY = 3, // Memory allocation failed
YAZE_ERROR_IO = 4, // I/O operation failed
YAZE_ERROR_CORRUPTION = 5, // Data corruption detected
YAZE_ERROR_NOT_INITIALIZED = 6, // Component not initialized

### Error Handling Pattern
```c
yaze_status status = yaze_library_init();
if (status != YAZE_OK) {
printf("Failed to initialize YAZE: %s\n", yaze_status_to_string(status));
return 1;
}
zelda3_rom* rom = yaze_load_rom("zelda3.sfc");
if (rom == nullptr) {
printf("Failed to load ROM file\n");
return 1;
}
// Use ROM...
yaze_unload_rom(rom);
yaze_library_shutdown();
```
## Extension System
### Plugin Architecture
```c
typedef struct yaze_extension {
const char* name; // Extension name
const char* version; // Version string
const char* description; // Description
const char* author; // Author
int api_version; // Required API version
yaze_status (*initialize)(yaze_editor_context* context);
void (*cleanup)(void);
uint32_t (*get_capabilities)(void);
} yaze_extension;
```
### Capability Flags
```c
#define YAZE_EXT_CAP_ROM_EDITING 0x0001 // ROM modification
#define YAZE_EXT_CAP_GRAPHICS 0x0002 // Graphics operations
#define YAZE_EXT_CAP_AUDIO 0x0004 // Audio processing
#define YAZE_EXT_CAP_SCRIPTING 0x0008 // Scripting support
#define YAZE_EXT_CAP_IMPORT_EXPORT 0x0010 // Data import/export
```
## Backward Compatibility
All existing code continues to work without modification due to:
- Legacy enum aliases (`US`, `JP`, `SD`, `RANDO`)
- Original struct field names maintained
- Duplicate field definitions for old/new naming conventions
- Typedef aliases for renamed types

# Getting Started
This software allows you to modify "The Legend of Zelda: A Link to the Past" (US or JP) ROMs. It is built for compatibility with ZScream projects and designed to be cross-platform.
## Quick Start
1. **Download** the latest release for your platform from the [releases page](https://github.com/scawful/yaze/releases).
2. **Load ROM** via `File > Open ROM`.
3. **Select an Editor** from the main toolbar (e.g., Overworld, Dungeon, Graphics).
4. **Make Changes** and save your project.
## General Tips
- **Experiment Flags**: Enable or disable new features in `File > Options > Experiment Flags`.
- **Backup Files**: Enabled by default. Each save creates a timestamped backup of your ROM.
- **Extensions**: Load custom tools via the `Extensions` menu (C library and Python module support is planned).
## Feature Status
| Feature | State | Notes |
|---|---|---|
| Overworld Editor | Stable | Supports vanilla and ZSCustomOverworld v2/v3 projects. |
| Dungeon Editor | Experimental | Requires extensive manual testing before production use. |
| Tile16 Editor | Experimental | Palette and tile workflows are still being tuned. |
| Palette Editor | Stable | Reference implementation for palette utilities. |
| Graphics Editor | Experimental | Rendering pipeline under active refactor. |
| Sprite Editor | Experimental | Card/UI patterns mid-migration. |
| Message Editor | Stable | Re-test after recent palette fixes. |
| Hex Editor | Stable | Direct ROM editing utility. |
| Asar Patching | Stable | Wraps the bundled Asar assembler. |
## Command-Line Interface (`z3ed`)
`z3ed` provides scripted access to the same ROM editors.
### AI Agent Chat
Chat with an AI to perform edits using natural language.
```bash
# Start an interactive chat session with the AI agent
z3ed agent chat --rom zelda3.sfc
```
> **Prompt:** "What sprites are in dungeon 2?"
### Resource Inspection
Directly query ROM data.
```bash
# List all sprites in the Eastern Palace (dungeon 2)
z3ed dungeon list-sprites --rom zelda3.sfc --dungeon 2
# Get information about a specific overworld map area
z3ed overworld describe-map --rom zelda3.sfc --map 80
```
### Patching
Apply assembly patches using the integrated Asar assembler.
```bash
# Apply an assembly patch to the ROM
z3ed asar patch.asm --rom zelda3.sfc
```
## Extending Functionality
YAZE exports a C API that is still evolving. Treat it as experimental and expect breaking changes while the plugin system is built out.

# A1 - Testing Guide
Comprehensive testing framework with efficient CI/CD integration and ROM-dependent test separation.
This guide provides a comprehensive overview of the testing framework for the yaze project, including the test organization, execution methods, and the end-to-end GUI automation system.
## Test Categories
## 1. Test Organization
### Stable Tests (STABLE)
**Always run in CI/CD - Required for releases**
The test suite is organized into a clear directory structure that separates tests by their purpose and dependencies. This is the primary way to understand the nature of a test.
- **AsarWrapperTest**: Core Asar functionality tests
- **SnesTileTest**: SNES tile format handling
- **CompressionTest**: Data compression/decompression
- **SnesPaletteTest**: SNES palette operations
- **HexTest**: Hexadecimal utilities
- **AsarIntegrationTest**: Asar integration without ROM dependencies
**Characteristics:**
- Fast execution (< 30 seconds total)
- No external dependencies (ROMs, complex setup)
- High reliability and deterministic results
### ROM-Dependent Tests (ROM_DEPENDENT)
**Only run in development with available ROM files**
- **AsarRomIntegrationTest**: Real ROM patching and symbol extraction
- **ROM-based integration tests**: Tests requiring actual game ROM files
**Characteristics:**
- Require specific ROM files to be present
- Test real-world functionality
- Automatically skipped in CI if ROM files unavailable
### Experimental Tests (EXPERIMENTAL)
**Run separately, allowed to fail**
- **CpuTest**: 65816 CPU emulation tests
- **Spc700Test**: SPC700 audio processor tests
- **ApuTest**: Audio Processing Unit tests
- **PpuTest**: Picture Processing Unit tests
**Characteristics:**
- May be unstable due to emulation complexity
- Test advanced/experimental features
- Allowed to fail without blocking releases
## Command Line Usage
```bash
# Run only stable tests (release-ready)
ctest --test-dir build --label-regex "STABLE"
# Run experimental tests (allowed to fail)
ctest --test-dir build --label-regex "EXPERIMENTAL"
# Run Asar-specific tests
ctest --test-dir build -R "*Asar*"
# Run tests excluding ROM-dependent ones
ctest --test-dir build --label-exclude "ROM_DEPENDENT"
# Run with specific preset
ctest --preset stable
ctest --preset experimental
```

## CMake Presets
## 2. Test Categories
Based on the directory structure, tests fall into the following categories:
### Unit Tests (`unit/`)
- **Purpose**: To test individual classes or functions in isolation.
- **Characteristics**:
- Fast, self-contained, and reliable.
- No external dependencies (e.g., ROM files, running GUI).
- Form the core of the CI/CD validation pipeline.
### Integration Tests (`integration/`)
- **Purpose**: To verify that different components of the application work together correctly.
- **Characteristics**:
- May require a real ROM file (especially those in `integration/zelda3/`). These are considered "ROM-dependent".
- Test interactions between modules, such as the `asar` wrapper and the `Rom` class, or AI services with the GUI controller.
- Slower than unit tests but crucial for catching bugs at module boundaries.
### End-to-End (E2E) Tests (`e2e/`)
- **Purpose**: To simulate a full user workflow from start to finish.
- **Characteristics**:
- Driven by the **ImGui Test Engine**.
- Almost always require a running GUI and often a real ROM.
- The slowest but most comprehensive tests, validating the user experience.
- Includes smoke tests, canvas interactions, and complex workflows like ZSCustomOverworld upgrades.
### Benchmarks (`benchmarks/`)
- **Purpose**: To measure and track the performance of critical code paths, particularly in the graphics system.
- **Characteristics**:
- Not focused on correctness but on speed and efficiency.
- Run manually or in specialized CI jobs to prevent performance regressions.
## 3. Running Tests
### Using the Enhanced Test Runner (`yaze_test`)
The most flexible way to run tests is by using the `yaze_test` executable directly. It provides flags to filter tests by category, which is ideal for development and AI agent workflows.
```bash
# Development workflow
cmake --preset dev
cmake --build --preset dev
# First, build the test executable
cmake --build build_ai --target yaze_test
# Run all tests
./build_ai/bin/yaze_test
# Run only unit tests
./build_ai/bin/yaze_test --unit
# Run only integration tests
./build_ai/bin/yaze_test --integration
# Run E2E tests (requires a GUI)
./build_ai/bin/yaze_test --e2e --show-gui
# Run ROM-dependent tests with a specific ROM
./build_ai/bin/yaze_test --rom-dependent --rom-path /path/to/zelda3.sfc
# Run tests matching a specific pattern (e.g., all Asar tests)
./build_ai/bin/yaze_test "*Asar*"
# Get a full list of options
./build_ai/bin/yaze_test --help
```
### Using CTest and CMake Presets
For CI/CD or a more traditional workflow, you can use `ctest` with CMake presets.
```bash
# Configure a development build (enables ROM-dependent tests)
cmake --preset mac-dev -DYAZE_TEST_ROM_PATH=/path/to/your/zelda3.sfc
# Build the tests
cmake --build --preset mac-dev --target yaze_test
# Run stable tests (fast, primarily unit tests)
ctest --preset dev
# CI workflow
cmake --preset ci
cmake --build --preset ci
ctest --preset ci
# Release workflow
cmake --preset release
cmake --build --preset release
ctest --preset stable
# Run all tests, including ROM-dependent and E2E
ctest --preset all
```
## Writing Tests
## 4. Writing Tests
### Stable Tests
```cpp
TEST(SnesTileTest, UnpackBppTile) {
std::vector<uint8_t> tile_data = {0xAA, 0x55, 0xAA, 0x55};
std::vector<uint8_t> result = UnpackBppTile(tile_data, 2);
EXPECT_EQ(result.size(), 64);
// Test specific pixel values...
}
When adding new tests, place them in the appropriate directory based on their purpose and dependencies.
- **New class `MyClass`?** Add `test/unit/my_class_test.cc`.
- **Testing `MyClass` with a real ROM?** Add `test/integration/my_class_rom_test.cc`.
- **Testing a full UI workflow involving `MyClass`?** Add `test/e2e/my_class_workflow_test.cc`.
## 5. E2E GUI Testing Framework
The E2E framework uses `ImGuiTestEngine` to automate UI interactions.
### Architecture
- **`test/yaze_test.cc`**: The main test runner that can initialize a GUI for E2E tests.
- **`test/e2e/`**: Contains all E2E test files, such as:
- `framework_smoke_test.cc`: Basic infrastructure verification.
- `canvas_selection_test.cc`: Canvas interaction tests.
- `dungeon_editor_tests.cc`: UI tests for the dungeon editor.
- **`test/test_utils.h`**: Provides high-level helper functions for common actions like loading a ROM (`LoadRomInTest`) or opening an editor (`OpenEditorInTest`).
### Running GUI Tests
To run E2E tests and see the GUI interactions, use the `--show-gui` flag.
```bash
# Run all E2E tests with the GUI visible
./build_ai/bin/yaze_test --e2e --show-gui
# Run a specific E2E test by name
./build_ai/bin/yaze_test --show-gui --gtest_filter="*DungeonEditorSmokeTest"
```
### ROM-Dependent Tests
```cpp
YAZE_ROM_TEST(AsarIntegration, RealRomPatching) {
auto rom_data = TestRomManager::LoadTestRom();
if (!rom_data.has_value()) {
GTEST_SKIP() << "ROM file not available";
}
AsarWrapper wrapper;
wrapper.Initialize();
auto result = wrapper.ApplyPatch("test.asm", *rom_data);
EXPECT_TRUE(result.ok());
}
```
### Widget Discovery and AI Integration
### Experimental Tests
```cpp
TEST(CpuTest, InstructionExecution) {
// Complex emulation tests
// May be timing-sensitive or platform-dependent
}
```
The GUI testing framework is designed for AI agent automation. All major UI elements are registered with stable IDs, allowing an agent to "discover" and interact with them programmatically via the `z3ed` CLI.
## CI/CD Integration
### GitHub Actions
```yaml
# Main CI pipeline
- name: Run Stable Tests
run: ctest --label-regex "STABLE"
# Experimental tests (allowed to fail)
- name: Run Experimental Tests
run: ctest --label-regex "EXPERIMENTAL"
continue-on-error: true
```
### Test Execution Strategy
1. **Stable tests run first** - Quick feedback for developers
2. **Experimental tests run in parallel** - Don't block on unstable tests
3. **ROM tests skipped** - No dependency on external files
4. **Selective test execution** - Only run relevant tests for changes
## Test Development Guidelines
### Writing Stable Tests
- **Fast execution**: Aim for < 1 second per test
- **No external dependencies**: Self-contained test data
- **Deterministic**: Same results every run
- **Core functionality**: Test essential features only
### Writing ROM-Dependent Tests
- **Use TestRomManager**: Proper ROM file handling
- **Graceful skipping**: Skip if ROM not available
- **Real-world scenarios**: Test with actual game data
- **Label appropriately**: Always include ROM_DEPENDENT label
### Writing Experimental Tests
- **Complex scenarios**: Multi-component integration
- **Advanced features**: Emulation, complex algorithms
- **Performance tests**: May vary by system
- **GUI components**: May require display context
## Performance and Maintenance
### Regular Review
- **Monthly review** of experimental test failures
- **Promote stable experimental tests** to stable category
- **Deprecate obsolete tests** that no longer provide value
- **Update test categorization** as features mature
### Performance Monitoring
- **Track test execution times** for CI efficiency
- **Identify slow tests** for optimization or recategorization
- **Monitor CI resource usage** and adjust parallelism
- **Benchmark critical path tests** for performance regression
Refer to the `z3ed` agent guide for details on using commands like `z3ed gui discover`, `z3ed gui click`, and `z3ed agent test replay`.

YAZE GUI Test Integration Refactoring Plan
Author: Gemini
Date: 2025-10-11
Status: Proposed
1. Introduction & Motivation
The yaze application includes a valuable feature for developers: an in-application "Test Dashboard" that allows for
viewing and running various test suites directly within the GUI. However, the current implementation, located primarily
in src/app/test/, is tightly coupled with both the main application and the command-line test executables.
This tight coupling has led to several architectural and practical problems:
* Conditional Compilation Complexity: Excluding the test dashboard from release or CI/CD builds is difficult, as its code
is intertwined with core application logic. This unnecessarily bloats release binaries with test code.
* Circular Dependencies: The yaze_test_support library, which contains the TestManager, links against nearly all other
application libraries (yaze_editor, yaze_gui, etc.). When the main application also links against yaze_test_support to
display the dashboard, it creates a confusing and potentially circular dependency graph that complicates the build
process.
* Mixed Concerns: The current TestManager is responsible for both the core logic of running tests and the UI logic for
displaying the dashboard. This violates the Single-Responsibility Principle and makes the code harder to maintain.
This document proposes a plan to refactor the test integration system into a modular, layered, and conditionally
compiled architecture.
2. Goals
* Decouple Test Infrastructure: Separate the core test framework from the test suites and the GUI dashboard.
* Create an Optional Test Dashboard: Make the in-app test dashboard a compile-time feature that can be easily enabled for
development builds and disabled for release builds.
* Eliminate Complex Dependencies: Remove the need for the main application to link against the entire suite of test
implementations, simplifying the build graph.
* Improve Maintainability: Create a clean and logical structure for the test system that is easier to understand and
extend.
3. Proposed Architecture
The test system will be decomposed into three distinct libraries, clearly separating the framework, the UI, and the
tests themselves.
1 +-----------------------------------------------------------------+
2 | Main Application ("yaze") |
3 | (Conditionally links against test_dashboard) |
4 +-----------------------------------------------------------------+
5 | ^
6 | Optionally depends on |
7 v |
8 +-----------------+ +-----------------+ +-----------------+
9 | test_dashboard | --> | test_framework | <-- | test_suites |
10 | (GUI Component) | | (Core Logic) | | (Test Cases) |
11 +-----------------+ +-----------------+ +-----------------+
12 ^ ^
13 | |
14 |-------------------------------------------------|
15 |
16 v
17 +-----------------------------------------------------------------+
18 | Test Executables (yaze_test_stable, etc.) |
19 | (Link against test_framework and test_suites) |
20 +-----------------------------------------------------------------+
3.1. test_framework (New Core Library)
* Location: src/test/framework/
* Responsibility: Provides the core, non-GUI logic for managing and executing tests.
* Contents:
* TestManager (core logic only: RunTests, RegisterTestSuite, GetLastResults, etc.).
* TestSuite base class and related structs (TestResult, TestResults, etc.).
* Dependencies: yaze_util, absl. It will not depend on yaze_gui or any specific test suites.
3.2. test_suites (New Library)
* Location: src/test/suites/
* Responsibility: Contains all the actual test implementations.
* Contents:
* E2ETestSuite, EmulatorTestSuite, IntegratedTestSuite, RomDependentTestSuite, ZSCustomOverworldTestSuite,
Z3edAIAgentTestSuite.
* Dependencies: test_framework, and any yaze libraries required for testing (e.g., yaze_zelda3, yaze_gfx).
3.3. test_dashboard (New Conditional GUI Library)
* Location: src/app/gui/testing/
* Responsibility: Contains all ImGui code for the in-application test dashboard. This library will be conditionally
compiled and linked.
* Contents:
* A new TestDashboard class containing the DrawTestDashboard method (migrated from TestManager).
* UI-specific logic for displaying results, configuring tests, and interacting with the TestManager.
* Dependencies: test_framework, yaze_gui.
4. Migration & Refactoring Plan
1. Create New Directory Structure:
* Create src/test/framework/.
* Create src/test/suites/.
* Create src/app/gui/testing/.
2. Split `TestManager`:
* Move test_manager.h and test_manager.cc to src/test/framework/.
* Create a new TestDashboard class in src/app/gui/testing/test_dashboard.h/.cc.
* Move the DrawTestDashboard method and all its UI-related helper functions from TestManager into the new
TestDashboard class.
* The TestDashboard will hold a reference to the TestManager singleton to access results and trigger test runs.
3. Relocate Test Suites:
* Move all ..._test_suite.h files from src/app/test/ to the new src/test/suites/ directory.
* Move z3ed_test_suite.cc to src/test/suites/.
4. Update CMake Configuration:
* `src/test/framework/CMakeLists.txt`: Create this file to define the yaze_test_framework static library.
* `src/test/suites/CMakeLists.txt`: Create this file to define the yaze_test_suites static library, linking it
against yaze_test_framework and other necessary yaze libraries.
* `src/app/gui/testing/CMakeLists.txt`: Create this file to define the yaze_test_dashboard static library.
* Root `CMakeLists.txt`: Introduce a new option: option(YAZE_WITH_TEST_DASHBOARD "Build the in-application test
dashboard" ON).
* `src/app/app.cmake`: Modify the yaze executable's target_link_libraries to conditionally link yaze_test_dashboard
based on the YAZE_WITH_TEST_DASHBOARD flag.
* `test/CMakeLists.txt`: Update the test executables to link against yaze_test_framework and yaze_test_suites.
* Remove `src/app/test/test.cmake`: The old yaze_test_support library will be completely replaced by this new
structure.
5. Expected Outcomes
This plan will resolve the current architectural issues by:
* Enabling Clean Builds: Release and CI builds can set YAZE_WITH_TEST_DASHBOARD=OFF, which will prevent the
test_dashboard and test_suites libraries from being compiled or linked into the final yaze executable, resulting in a
smaller, cleaner binary.
* Simplifying Dependencies: The main application will no longer have a convoluted dependency on its own test suites. The
dependency graph will be clear and acyclic.
* Improving Developer Experience: Developers can enable the dashboard for convenient in-app testing, while the core test
infrastructure remains robust and decoupled for command-line execution.

# Build Instructions
yaze uses a modern CMake build system with presets for easy configuration. This guide covers how to build yaze on macOS, Linux, and Windows.
## 1. Environment Verification
**Before your first build**, run the verification script to ensure your environment is configured correctly.
### Windows (PowerShell)
```powershell
.\scripts\verify-build-environment.ps1
# With automatic fixes
.\scripts\verify-build-environment.ps1 -FixIssues
```
### macOS & Linux (Bash)
```bash
./scripts/verify-build-environment.sh
# With automatic fixes
./scripts\verify-build-environment.sh --fix
```
The script checks for required tools like CMake, a C++23 compiler, and platform-specific dependencies.
## 2. Quick Start: Building with Presets
We use CMake Presets for simple, one-command builds. See the [CMake Presets Guide](B3-build-presets.md) for a full list.
### macOS
```bash
# Configure a debug build (Apple Silicon)
cmake --preset mac-dbg
# Build the project
cmake --build --preset mac-dbg
```
### Linux
```bash
# Configure a debug build
cmake --preset lin-dbg
# Build the project
cmake --build --preset lin-dbg
```
### Windows
```bash
# Configure a debug build for Visual Studio (x64)
cmake --preset win-dbg
# Build the project
cmake --build --preset win-dbg
```
### AI-Enabled Build (All Platforms)
To build with the `z3ed` AI agent features:
```bash
# macOS
cmake --preset mac-ai
cmake --build --preset mac-ai
# Windows
cmake --preset win-ai
cmake --build --preset win-ai
```
## 3. Dependencies
- **Required**: CMake 3.16+, C++23 Compiler (GCC 13+, Clang 16+, MSVC 2019+), Git.
- **Bundled**: All other dependencies (SDL2, ImGui, Abseil, Asar, GoogleTest, etc.) are included as Git submodules or managed by CMake's `FetchContent`. No external package manager is required for a basic build.
- **Optional**:
- **gRPC**: For GUI test automation. Can be enabled with `-DYAZE_WITH_GRPC=ON`.
- **vcpkg (Windows)**: Can be used for dependency management, but is not required.
## 4. Platform Setup
### macOS
```bash
# Install Xcode Command Line Tools
xcode-select --install
# Recommended: Install build tools via Homebrew
brew install cmake pkg-config
```
### Linux (Ubuntu/Debian)
```bash
sudo apt-get update
sudo apt-get install -y build-essential cmake ninja-build pkg-config \
libgtk-3-dev libdbus-1-dev
```
### Windows
- **Visual Studio 2022** is required, with the "Desktop development with C++" workload.
- The `verify-build-environment.ps1` script will help identify any missing components.
- For building with gRPC, see the "Windows Build Optimization" section below.
## 5. Testing
The project uses CTest and GoogleTest. Tests are organized into categories using labels. See the [Testing Guide](A1-testing-guide.md) for details.
### Running Tests with Presets
The easiest way to run tests is with `ctest` presets.
```bash
# Configure a development build (enables ROM-dependent tests)
cmake --preset mac-dev -DYAZE_TEST_ROM_PATH=/path/to/your/zelda3.sfc
# Build the tests
cmake --build --preset mac-dev --target yaze_test
# Run stable tests (fast, run in CI)
ctest --preset dev
# Run all tests, including ROM-dependent and experimental
ctest --preset all
```
### Running Tests Manually
You can also run tests by invoking the test executable directly or using CTest with labels.
```bash
# Run all tests via the executable
./build/bin/yaze_test
# Run only stable tests using CTest labels
ctest --test-dir build --label-regex "STABLE"
# Run tests matching a name
ctest --test-dir build -R "AsarWrapperTest"
# Exclude ROM-dependent tests
ctest --test-dir build --label-exclude "ROM_DEPENDENT"
```
## 6. IDE Integration
### VS Code (Recommended)
1. Install the **CMake Tools** extension.
2. Open the project folder.
3. Select a preset from the status bar (e.g., `mac-ai`).
4. Press F5 to build and debug.
5. After changing presets, run `cp build/compile_commands.json .` to update IntelliSense.
### Visual Studio (Windows)
1. Select **File → Open → Folder** and choose the `yaze` directory.
2. Visual Studio will automatically detect `CMakePresets.json`.
3. Select the desired preset (e.g., `win-dbg` or `win-ai`) from the configuration dropdown.
4. Press F5 to build and run.
### Xcode (macOS)
```bash
# Generate an Xcode project from a preset
cmake --preset mac-dbg -G Xcode
# Open the project
open build/yaze.xcodeproj
```
## 7. Windows Build Optimization
### GitHub Actions / CI Builds
**Current Configuration (Optimized):**
- **Compilers**: Both clang-cl and MSVC supported (matrix)
- **vcpkg**: Only fast packages (SDL2, yaml-cpp) - 2 minutes
- **gRPC**: Built via FetchContent (v1.67.1) - cached after first build
- **Caching**: Aggressive multi-tier caching (vcpkg + FetchContent + sccache)
- **Expected time**:
- First build: ~10-15 minutes
- Cached build: ~3-5 minutes
**Why Not vcpkg for gRPC?**
- vcpkg's latest gRPC (v1.71.0) has no pre-built binaries
- Building from source via vcpkg: 45-90 minutes
- FetchContent with caching: 10-15 minutes first time, <1 min cached
- Better control over gRPC version (v1.75.1 with Windows fixes)
- BoringSSL ASM disabled on Windows for clang-cl compatibility
- zlib conflict: gRPC's FetchContent builds its own zlib, conflicts with vcpkg's
### Local Development
#### Fast Build (Recommended)
Use FetchContent for all dependencies (matches CI):
```powershell
# Configure (first time: ~15 min, subsequent: ~2 min)
cmake -B build -G "Visual Studio 17 2022" -A x64
# Build
cmake --build build --config RelWithDebInfo --parallel
```
#### Using vcpkg (Optional)
If you prefer vcpkg for local development:
```powershell
# Install ONLY the fast packages
vcpkg install sdl2:x64-windows yaml-cpp:x64-windows
# Let CMake use FetchContent for gRPC
cmake -B build -DCMAKE_TOOLCHAIN_FILE=vcpkg/scripts/buildsystems/vcpkg.cmake
```
**DO NOT** install grpc or zlib via vcpkg:
- gRPC v1.71.0 has no pre-built binaries (45-90 min build)
- zlib conflicts with gRPC's bundled zlib
### Compiler Support
**clang-cl (Recommended):**
- Used in both CI and release workflows
- Better diagnostics than MSVC
- Fully compatible with MSVC libraries
**MSVC:**
- Also tested in CI matrix
- Fallback option if clang-cl issues occur
**Compiler Flags (Applied Automatically):**
- `/bigobj` - Large object files (required for gRPC)
- `/permissive-` - Standards conformance
- `/wd4267 /wd4244` - Suppress harmless conversion warnings
- `/constexpr:depth2048` - Template instantiation depth
## 8. Troubleshooting
Build issues, especially on Windows, often stem from environment misconfiguration. Before anything else, run the verification script.
```powershell
# Run the verification script in PowerShell
.\scripts\verify-build-environment.ps1
```
This script is your primary diagnostic tool and can detect most common problems.
### Automatic Fixes
If the script finds issues, you can often fix them automatically by running it with the `-FixIssues` flag. This can:
- Synchronize Git submodules.
- Correct Git `core.autocrlf` and `core.longpaths` settings, which are critical for cross-platform compatibility on Windows.
- Prompt to clean stale CMake caches.
```powershell
# Attempt to fix detected issues automatically
.\scripts\verify-build-environment.ps1 -FixIssues
```
### Cleaning Stale Builds
After pulling major changes or switching branches, your build directory can become "stale," leading to strange compiler or linker errors. The verification script will warn you about old build files. You can clean them manually or use the `-CleanCache` flag.
**This will delete all `build*` and `out` directories.**
```powershell
# Clean all build artifacts to start fresh
.\scripts\verify-build-environment.ps1 -CleanCache
```
### Common Issues
#### "nlohmann/json.hpp: No such file or directory"
**Cause**: You are building code that requires AI features without using an AI-enabled preset, or your Git submodules are not initialized.
**Solution**:
1. Use an AI preset like `win-ai` or `mac-ai`.
2. Ensure submodules are present by running `git submodule update --init --recursive`.
#### "Cannot open file 'yaze.exe': Permission denied"
**Cause**: A previous instance of `yaze.exe` is still running in the background.
**Solution**: Close it using Task Manager or run:
```cmd
taskkill /F /IM yaze.exe
```
#### "C++ standard 'cxx_std_23' not supported"
**Cause**: Your compiler is too old.
**Solution**: Update your tools. You need Visual Studio 2022 17.4+, GCC 13+, or Clang 16+. The verification script checks this.
#### Visual Studio Can't Find Presets
**Cause**: VS failed to parse `CMakePresets.json` or its cache is corrupt.
**Solution**:
1. Close and reopen the folder (`File -> Close Folder`).
2. Check the "CMake" pane in the Output window for specific JSON parsing errors.
3. Delete the hidden `.vs` directory in the project root to force Visual Studio to re-index the project.
#### Git Line Ending (CRLF) Issues
**Cause**: Git may be automatically converting line endings, which can break shell scripts and other assets.
**Solution**: The verification script checks for this. Use the `-FixIssues` flag or run `git config --global core.autocrlf false` to prevent this behavior.
#### File Path Length Limit on Windows
**Cause**: By default, Windows has a 260-character path limit, which can be exceeded by nested dependencies.
**Solution**: The verification script checks for this. Use the `-FixIssues` flag or run `git config --global core.longpaths true` to enable long path support.

std::vector<uint8_t> data_;
};
}
```
### Error Handling
```cpp
// Use absl::Status for error handling
absl::Status LoadRom(const std::string& filename) {
if (filename.empty()) {
return absl::InvalidArgumentError("Filename cannot be empty");
}
// ... implementation
return absl::OkStatus();
}
// Use absl::StatusOr for operations that return values
absl::StatusOr<std::vector<uint8_t>> ReadFile(const std::string& filename);
```
## Testing Requirements
### Test Categories
- **Stable Tests**: Fast, reliable, no external dependencies
- **ROM-Dependent Tests**: Require ROM files, skip in CI
- **Experimental Tests**: Complex, may be unstable
### Writing Tests
```cpp
// Stable test example
TEST(SnesTileTest, UnpackBppTile) {
std::vector<uint8_t> tile_data = {0xAA, 0x55};
auto result = UnpackBppTile(tile_data, 2);
EXPECT_TRUE(result.ok());
EXPECT_EQ(result->size(), 64);
}
// ROM-dependent test example
YAZE_ROM_TEST(AsarIntegration, RealRomPatching) {
auto rom_data = TestRomManager::LoadTestRom();
if (!rom_data.has_value()) {
GTEST_SKIP() << "ROM file not available";
}
// ... test implementation
}
```
### Test Execution
```bash
# Run stable tests (required)
ctest --label-regex "STABLE"
# Run experimental tests (optional)
ctest --label-regex "EXPERIMENTAL"
# Run specific test
ctest -R "AsarWrapperTest"
```
## Pull Request Process
### Before Submitting
1. **Run tests**: Ensure all stable tests pass
2. **Check formatting**: Use clang-format
3. **Update documentation**: Update relevant docs if needed
4. **Test on multiple platforms**: Verify cross-platform compatibility

# Platform Compatibility Improvements
# Platform Compatibility & CI/CD Fixes
Recent improvements to ensure YAZE works reliably across all supported platforms.
**Last Updated**: October 9, 2025
---
## Platform-Specific Notes
### Windows
**Build System:**
- Supported compilers: clang-cl (preferred), MSVC 2022 17.4+
- Uses vcpkg for: SDL2, yaml-cpp (fast packages only)
- Uses FetchContent for: gRPC v1.75.1, protobuf, abseil, zlib (better caching)
**Why FetchContent for gRPC?**
- vcpkg gRPC v1.71.0 has no pre-built binaries (builds from source: 45-90 min)
- FetchContent uses v1.75.1 with Windows compatibility fixes
- BoringSSL ASM disabled on Windows (avoids NASM build conflicts with clang-cl)
- Better caching in CI/CD (separate cache keys for vcpkg vs FetchContent)
- First build: ~10-15 min, subsequent: <1 min (cached)
- zlib bundled with gRPC (avoids vcpkg conflicts)
**Compiler Flags (both clang-cl and MSVC):**
- `/bigobj` - Support large object files (required for gRPC)
- `/permissive-` - Standards conformance mode
- `/wd4267 /wd4244` - Suppress harmless conversion warnings
- `/constexpr:depth2048` - Deep template instantiation (MSVC 2019+)
**Macro Definitions:**
- `WIN32_LEAN_AND_MEAN` - Reduce Windows header pollution
- `NOMINMAX` - Prevent min/max macro conflicts
- `NOGDI` - Prevent GDI macro conflicts (DWORD, etc.)
- `__PRFCHWINTRIN_H` - Work around Clang 20 `_m_prefetchw` linkage clash
**Build Times:**
- First build (no cache): ~10-15 minutes
- Incremental build (cached): ~3-5 minutes
- CI/CD with full caching: ~5-8 minutes
**CI/CD Configuration:**
- Compiler matrix: clang-cl + MSVC
- 3-tier caching: vcpkg packages, FetchContent deps, sccache objects
- Binary caching via GitHub Actions for vcpkg
- Parallel builds: 4 jobs
### macOS
**Build System:**
- Uses vcpkg for: SDL2, yaml-cpp, zlib
- Uses FetchContent for: gRPC, abseil, protobuf
**Supported Architectures:**
- x64 (Intel Macs) - macOS 13+
- ARM64 (Apple Silicon) - macOS 14+
**Build Times:**
- First build: ~20-30 minutes
- Subsequent builds: ~3-5 minutes
### Linux
**Build System:**
- Uses system packages (apt) for most dependencies
- Does NOT use vcpkg
- Uses FetchContent for: gRPC, abseil, protobuf (when not in system)
**Required System Packages:**
```bash
build-essential ninja-build pkg-config libglew-dev libxext-dev
libwavpack-dev libabsl-dev libboost-all-dev libpng-dev python3-dev
libpython3-dev libasound2-dev libpulse-dev libaudio-dev libx11-dev
libxrandr-dev libxcursor-dev libxinerama-dev libxi-dev libxss-dev
libxxf86vm-dev libxkbcommon-dev libwayland-dev libdecor-0-dev
libgtk-3-dev libdbus-1-dev gcc-12 g++-12 clang-15
```
**Build Times:**
- First build: ~15-20 minutes
- Subsequent builds: ~2-4 minutes
---
## Cross-Platform Code Validation
The following subsystems run unchanged across Windows, macOS, and Linux:
- Audio backend (`src/app/emu/audio`) uses SDL2 only; no platform branches.
- Input backend/manager (`src/app/emu/input`) runs on SDL2 abstractions.
- Debug tools (`src/app/emu/debug`) avoid OS-specific headers.
- Emulator UI (`src/app/emu/ui`) is pure ImGui + SDL2.
---
## Common Build Issues & Solutions
### Windows: "use of undefined type 'PromiseLike'"
**Cause:** Old gRPC version (< v1.67.1)
**Fix:** Clear build cache and reconfigure
```powershell
rm -r build/_deps/grpc-*
cmake -B build -G "Visual Studio 17 2022" -A x64
```
### macOS: "absl not found"
**Cause:** vcpkg not finding abseil packages
**Fix:** Use FetchContent (default) - abseil is fetched automatically by gRPC
```bash
cmake -B build
```
### Linux: CMake configuration fails
**Cause:** Missing system dependencies
**Fix:** Install required packages
```bash
sudo apt-get update
sudo apt-get install -y [see package list above]
```
### Windows: "DWORD syntax error"
**Cause:** Windows macros conflicting with protobuf enums
**Fix:** Ensure `NOGDI` is defined (now automatic in grpc.cmake)
---
## CI/CD Validation Checklist
Before merging platform-specific changes:
- Confirm the vcpkg baseline matches `vcpkg.json`.
- Do not reintroduce the Windows x86 build (cpp-httplib incompatibility).
- Keep Windows macro guards (`NOGDI`, `NOMINMAX`, `WIN32_LEAN_AND_MEAN`) in place.
- Build against gRPC 1.67.1 with the MSVC workaround flags.
- Leave shared code paths on SDL2/ImGui abstractions.
- Re-run the full matrix if caches or presets change.
### CI/CD Performance Roadmap
- **Dependency caching**: Cache vcpkg installs on Windows plus Homebrew/apt
archives to trim 5-10 minutes per job; track cache keys via OS + lockfiles.
- **Compiler caching**: Enable `ccache`/`sccache` across the matrix using the
`hendrikmuhs/ccache-action` with 500 MB per-run limits for 3-5 minute wins.
- **Conditional work**: Add a path-filter job that skips emulator builds or
full test runs when only docs or CLI code change; fall back to full matrix on
shared components.
- **Reusable workflows**: Centralize setup steps (checking out submodules,
restoring caches, configuring presets) to reduce duplication between `ci.yml`
and `release.yml`.
- **Release optimizations**: Use lean presets without test targets, run platform
builds in parallel, and reuse cached artifacts from CI when hashes match.
---
## Testing Strategy
### Automated (CI)
- Ubuntu 22.04 (GCC-12, Clang-15)
- macOS 13/14 (x64 and ARM64)
- Windows Server 2022 (x64)
- Core tests: `AsarWrapperTest`, `SnesTileTest`, others tagged `STABLE`
- Tooling: clang-format, clang-tidy, cppcheck
- Sanitizers: Linux AddressSanitizer job
### Manual Testing
After successful CI build:
- Windows: verify audio backend, keyboard input, APU debugger UI.
- Linux: verify input polling and audio output.
- macOS: spot-check rendering, input, audio.
---
## Quick Reference
### Build Command (All Platforms)
```bash
cmake -B build
cmake --build build --parallel
cmake --preset [mac-dbg|lin-dbg|win-dbg]
cmake --build --preset [mac-dbg|lin-dbg|win-dbg]
```
### Enable Features
All features (JSON, gRPC, AI) are **always enabled** by default.
No need to specify `-DZ3ED_AI=ON` or `-DYAZE_WITH_GRPC=ON`.
### Windows Troubleshooting
```powershell
# Verify environment
.\scripts\verify-build-environment.ps1
# Use vcpkg for faster builds
.\scripts\setup-vcpkg-windows.ps1
cmake -B build -DCMAKE_TOOLCHAIN_FILE="vcpkg/scripts/buildsystems/vcpkg.cmake"
```
---
## Filesystem Abstraction
To ensure robust and consistent behavior across platforms, YAZE has standardized its filesystem operations:
- **`std::filesystem`**: All new and refactored code uses the C++17 `std::filesystem` library for path manipulation, directory iteration, and file operations. This eliminates platform-specific bugs related to path separators (`/` vs `\`).
- **`PlatformPaths` Utility**: A dedicated utility class, `yaze::util::PlatformPaths`, provides platform-aware API for retrieving standard directory locations:
- **Application Data**: `%APPDATA%` on Windows, `~/Library/Application Support` on macOS, XDG Base Directory on Linux
- **Configuration Files**: Semantically clear API for config file locations
- **Home and Temporary Directories**: Safely resolves user-specific and temporary folders
This removes legacy platform-specific APIs (like `dirent.h` or Win32 directory functions) for cleaner, more maintainable file handling.
---
## Native File Dialog Support
YAZE now features native file dialogs on all platforms:
YAZE features native file dialogs on all platforms:
- **macOS**: Cocoa-based file selection with proper sandboxing support
- **Windows**: Windows Explorer integration with COM APIs
- **Windows**: Windows Explorer integration with COM APIs (`IFileOpenDialog`/`IFileSaveDialog`)
- **Linux**: GTK3 dialogs that match system appearance
- **Fallback**: Bespoke implementation when native dialogs unavailable
- **Fallback**: Cross-platform implementation when native dialogs unavailable
## Cross-Platform Build Reliability
---
Enhanced build system ensures consistent compilation:
- **Windows**: Resolved MSVC compatibility issues and dependency conflicts
- **Linux**: Fixed standard library compatibility for older distributions
- **macOS**: Proper support for both Intel and Apple Silicon architectures
- **All Platforms**: Bundled dependencies eliminate external package requirements
## Build Configuration Options
YAZE supports different build configurations for various use cases:
### Full Build (Development)
Includes all features: emulator, CLI tools, UI testing framework, and optional libraries.
### Minimal Build
Streamlined build excluding complex components, optimized for automated testing and CI environments.
## Implementation Details
The build system automatically detects platform capabilities and adjusts feature sets accordingly:
- **File Dialogs**: Uses native platform dialogs when available, with cross-platform fallbacks
- **Dependencies**: Bundles all required libraries to eliminate external package requirements
- **Testing**: Separates ROM-dependent tests from unit tests for CI compatibility
- **Architecture**: Supports both Intel and Apple Silicon on macOS without conflicts
## Platform-Specific Adaptations
### Windows
- Complete COM-based file dialog implementation
- MSVC compatibility improvements for modern C++ features
- Resource file handling for proper application integration
### macOS
- Cocoa-based native file dialogs with sandboxing support
- Universal binary support for Intel and Apple Silicon
- Proper bundle configuration for macOS applications
### Linux
- GTK3 integration for native file dialogs
- Package manager integration for system dependencies
- Support for multiple compiler toolchains (GCC, Clang)
**Status:** All CI/CD issues resolved. Next push should build successfully on all platforms.

# Build Presets Guide
CMake presets for development workflow and architecture-specific builds.
This document explains the reorganized CMake preset system for Yaze.
## 🍎 macOS ARM64 Presets (Recommended for Apple Silicon)
## Design Principles
### For Development Work:
1. **Short, memorable names** - No more `macos-dev-z3ed-ai`, just `mac-ai`
2. **Warnings off by default** - Add `-v` suffix for verbose (e.g., `mac-dbg-v`)
3. **Clear architecture support** - Explicit ARM64 and x86_64 presets
4. **Platform prefixes** - `mac-`, `win-`, `lin-` for easy identification
## Quick Start
### macOS Development
```bash
# ARM64-only development build with ROM testing
cmake --preset macos-dev
cmake --build --preset macos-dev
# Most common: AI-enabled development
cmake --preset mac-ai
cmake --build --preset mac-ai
# ARM64-only debug build
cmake --preset macos-debug
cmake --build --preset macos-debug
# Basic debug build (no AI)
cmake --preset mac-dbg
cmake --build --preset mac-dbg
# ARM64-only release build
cmake --preset macos-release
cmake --build --preset macos-release
# Verbose warnings for debugging
cmake --preset mac-dbg-v
cmake --build --preset mac-dbg-v
# Release build
cmake --preset mac-rel
cmake --build --preset mac-rel
```
### For Distribution:
### Windows Development
```bash
# Universal binary (ARM64 + x86_64) - use only when needed for distribution
cmake --preset macos-debug-universal
cmake --build --preset macos-debug-universal
# Debug build (x64)
cmake --preset win-dbg
cmake --build --preset win-dbg
cmake --preset macos-release-universal
cmake --build --preset macos-release-universal
# AI-enabled development
cmake --preset win-ai
cmake --build --preset win-ai
# ARM64 support
cmake --preset win-arm
cmake --build --preset win-arm
```
## 🔧 Why This Fixes Architecture Errors
## All Presets
**Problem**: The original presets used `CMAKE_OSX_ARCHITECTURES: "x86_64;arm64"` which forced CMake to build universal binaries. This caused issues because:
- Dependencies like Abseil tried to use x86 SSE instructions (`-msse4.1`)
- These instructions don't exist on ARM64 processors
- Build failed with "unsupported option '-msse4.1' for target 'arm64-apple-darwin'"
### macOS Presets
**Solution**: The new ARM64-only presets use `CMAKE_OSX_ARCHITECTURES: "arm64"` which:
- ✅ Only targets ARM64 architecture
- ✅ Prevents x86-specific instruction usage
- ✅ Uses ARM64 optimizations instead
- ✅ Builds much faster (no cross-compilation)
| Preset | Description | Arch | Warnings | Features |
|--------|-------------|------|----------|----------|
| `mac-dbg` | Debug build | ARM64 | Off | Basic |
| `mac-dbg-v` | Debug verbose | ARM64 | On | Basic |
| `mac-rel` | Release | ARM64 | Off | Basic |
| `mac-x64` | Debug x86_64 | x86_64 | Off | Basic |
| `mac-uni` | Universal binary | Both | Off | Basic |
| `mac-dev` | Development | ARM64 | Off | ROM tests |
| `mac-ai` | AI development | ARM64 | Off | z3ed, JSON, gRPC, ROM tests |
| `mac-z3ed` | z3ed CLI | ARM64 | Off | AI agent support |
| `mac-rooms` | Dungeon editor | ARM64 | Off | Minimal build for room editing |
## 📋 Available Presets
### Windows Presets
| Preset Name | Architecture | Purpose | ROM Tests |
|-------------|-------------|---------|-----------|
| `macos-dev` | ARM64 only | Development | ✅ Enabled |
| `macos-debug` | ARM64 only | Debug builds | ❌ Disabled |
| `macos-release` | ARM64 only | Release builds | ❌ Disabled |
| `macos-debug-universal` | Universal | Distribution debug | ❌ Disabled |
| `macos-release-universal` | Universal | Distribution release | ❌ Disabled |
| Preset | Description | Arch | Warnings | Features |
|--------|-------------|------|----------|----------|
| `win-dbg` | Debug build | x64 | Off | Basic |
| `win-dbg-v` | Debug verbose | x64 | On | Basic |
| `win-rel` | Release | x64 | Off | Basic |
| `win-arm` | Debug ARM64 | ARM64 | Off | Basic |
| `win-arm-rel` | Release ARM64 | ARM64 | Off | Basic |
| `win-dev` | Development | x64 | Off | ROM tests |
| `win-ai` | AI development | x64 | Off | z3ed, JSON, gRPC, ROM tests |
| `win-z3ed` | z3ed CLI | x64 | Off | AI agent support |
## 🚀 Quick Start
### Linux Presets
For most development work on Apple Silicon:
| Preset | Description | Compiler | Warnings |
|--------|-------------|----------|----------|
| `lin-dbg` | Debug | GCC | Off |
| `lin-clang` | Debug | Clang | Off |
### Special Purpose
| Preset | Description |
|--------|-------------|
| `ci` | Continuous integration (no ROM tests) |
| `asan` | AddressSanitizer build |
| `coverage` | Code coverage build |
## Warning Control
By default, all presets suppress compiler warnings with `-w` for a cleaner build experience.
### To Enable Verbose Warnings:
1. Use a preset with `-v` suffix (e.g., `mac-dbg-v`, `win-dbg-v`)
2. Or set `YAZE_SUPPRESS_WARNINGS=OFF` manually:
```bash
cmake --preset mac-dbg -DYAZE_SUPPRESS_WARNINGS=OFF
```
## Architecture Support
### macOS
- **ARM64 (Apple Silicon)**: `mac-dbg`, `mac-rel`, `mac-ai`, etc.
- **x86_64 (Intel)**: `mac-x64`
- **Universal Binary**: `mac-uni` (both ARM64 + x86_64)
### Windows
- **x64**: `win-dbg`, `win-rel`, `win-ai`, etc.
- **ARM64**: `win-arm`, `win-arm-rel`
## Build Directories
Most presets use `build/` directory. Exceptions:
- `mac-rooms`: Uses `build_rooms/` to avoid conflicts
## Feature Flags
Common CMake options you can override:
```bash
# Clean build
rm -rf build
# Enable/disable components
-DYAZE_BUILD_TESTS=ON/OFF
-DYAZE_BUILD_Z3ED=ON/OFF
-DYAZE_BUILD_EMU=ON/OFF
-DYAZE_BUILD_APP=ON/OFF
# Configure for ARM64 development
cmake --preset macos-dev
# AI features
-DZ3ED_AI=ON/OFF
-DYAZE_WITH_JSON=ON/OFF
-DYAZE_WITH_GRPC=ON/OFF
# Build
cmake --build --preset macos-dev
# Testing
-DYAZE_ENABLE_ROM_TESTS=ON/OFF
-DYAZE_TEST_ROM_PATH=/path/to/zelda3.sfc
# Run tests
cmake --build --preset macos-dev --target test
# Build optimization
-DYAZE_MINIMAL_BUILD=ON/OFF
```
## 🛠️ IDE Integration
## Examples
### VS Code with CMake Tools:
1. Open Command Palette (`Cmd+Shift+P`)
2. Run "CMake: Select Configure Preset"
3. Choose `macos-dev` or `macos-debug`
### CLion:
1. Go to Settings → Build, Execution, Deployment → CMake
2. Add new profile with preset `macos-dev`
### Xcode:
### Development with AI features and verbose warnings
```bash
# Generate Xcode project
cmake --preset macos-debug -G Xcode
open build/yaze.xcodeproj
cmake --preset mac-dbg-v -DZ3ED_AI=ON -DYAZE_WITH_GRPC=ON
cmake --build --preset mac-dbg-v
```
## 🔍 Troubleshooting
### Release build for distribution (macOS Universal)
```bash
cmake --preset mac-uni
cmake --build --preset mac-uni
cpack --preset mac-uni
```
If you still get architecture errors:
1. **Clean completely**: `rm -rf build`
2. **Check preset**: Ensure you're using an ARM64 preset (not universal)
3. **Verify configuration**: Check that `CMAKE_OSX_ARCHITECTURES` shows only `arm64`
### Quick minimal build for testing
```bash
cmake --preset mac-dbg -DYAZE_MINIMAL_BUILD=ON
cmake --build --preset mac-dbg -j12
```
## Updating compile_commands.json
After configuring with a new preset, copy the compile commands for IDE support:
```bash
# Verify architecture setting
cmake --preset macos-debug
grep -A 5 -B 5 "CMAKE_OSX_ARCHITECTURES" build/CMakeCache.txt
cp build/compile_commands.json .
```
## 📝 Notes
This ensures clangd and other LSP servers can find headers and understand build flags.
- **ARM64 presets**: Fast builds, no architecture conflicts
- **Universal presets**: Slower builds, for distribution only
- **Deployment target**: ARM64 presets use macOS 11.0+ (when Apple Silicon was introduced)
- **Universal presets**: Still support macOS 10.15+ for backward compatibility
## Migration from Old Presets
Old preset names have been simplified:
| Old Name | New Name |
|----------|----------|
| `macos-dev-z3ed-ai` | `mac-ai` |
| `macos-debug` | `mac-dbg` |
| `macos-release` | `mac-rel` |
| `macos-debug-universal` | `mac-uni` |
| `macos-dungeon-dev` | `mac-rooms` |
| `windows-debug` | `win-dbg` |
| `windows-release` | `win-rel` |
| `windows-arm64-debug` | `win-arm` |
| `linux-debug` | `lin-dbg` |
| `linux-clang` | `lin-clang` |
## Troubleshooting
### Warnings are still showing
- Make sure you're using a preset without `-v` suffix
- Check `cmake` output for `✓ Warnings suppressed` message
- Reconfigure and rebuild: `rm -rf build && cmake --preset mac-dbg`
### clangd can't find nlohmann/json
- Run `cmake --preset <your-preset>` to regenerate compile_commands.json
- Copy to root: `cp build/compile_commands.json .`
- Restart your IDE or LSP server
### Build fails with missing dependencies
- Ensure submodules are initialized: `git submodule update --init --recursive`
- For AI features, make sure you have OpenSSL: `brew install openssl` (macOS)

# Git Workflow and Branching Strategy
**Last Updated:** October 10, 2025
**Status:** Active
**Current Phase:** Pre-1.0 (Relaxed Rules)
## Warning: Pre-1.0 Workflow (Current)
**TLDR for now:** Since yaze is pre-1.0 and actively evolving, we use a **simplified workflow**:
- **Documentation changes**: Commit directly to `master` or `develop`
- **Small bug fixes**: Can go direct to `develop`, no PR required
- **Solo work**: Push directly when you're the only one working
- Warning: **Breaking changes**: Use feature branches and document in changelog
- Warning: **Major refactors**: Use feature branches for safety (can always revert)
**Why relaxed?**
- Small team / solo development
- Pre-1.0 means breaking changes are expected
- Documentation needs to be public quickly
- Overhead of PRs/reviews slows down experimentation
**When to transition to strict workflow:**
- Multiple active contributors
- Stable API (post-1.0)
- Large user base depending on stability
- Critical bugs need rapid hotfixes
---
## Pre-1.0 Release Strategy: Best Effort Releases
For all versions prior to 1.0.0, yaze follows a **"best effort"** release strategy. This prioritizes getting working builds to users quickly, even if not all platforms build successfully on the first try.
### Core Principles
1. **Release Can Proceed with Failed Platforms**: The `release` CI/CD workflow will create a GitHub Release even if one or more platform-specific build jobs (e.g., Windows, Linux, macOS) fail.
2. **Missing Platforms Can Be Added Later**: A failed job for a specific platform can be re-run from the GitHub Actions UI. If it succeeds, the binary artifact will be **automatically added to the existing GitHub Release**.
3. **Transparency is Key**: The release notes will automatically generate a "Platform Availability" report, clearly indicating which platforms succeeded () and which failed (❌), so users know the current status.
### How It Works in Practice
- The `build-and-package` jobs in the `release.yml` workflow have `continue-on-error: true`.
- The final `create-github-release` job has `if: always()` and uses `softprops/action-gh-release@v2`, which intelligently updates an existing release if the tag already exists.
- If a platform build fails, a developer can investigate the issue and simply re-run the failed job. Upon success, the new binary is uploaded and attached to the release that was already created.
This strategy provides flexibility and avoids blocking a release for all users due to a transient issue on a single platform. Once the project reaches v1.0.0, this policy will be retired in favor of a stricter approach where all platforms must pass for a release to proceed.
---
## 📚 Full Workflow Reference (Future/Formal)
The sections below document the **formal Git Flow model** that yaze will adopt post-1.0 or when the team grows. For now, treat this as aspirational best practices.
## Branch Structure
### Main Branches
#### `master`
- **Purpose**: Production-ready release branch
- **Protection**: Protected, requires PR approval
- **Versioning**: Tagged with semantic versions (e.g., `v0.3.2`, `v0.4.0`)
- **Updates**: Only via approved PRs from `develop` or hotfix branches
#### `develop`
- **Purpose**: Main development branch, integration point for all features
- **Protection**: Protected, requires PR approval
- **State**: Should always build and pass tests
- **Updates**: Merges from feature branches, releases merge back after tagging
### Supporting Branches
#### Feature Branches
**Naming Convention:** `feature/<short-description>`
**Examples:**
- `feature/overworld-editor-improvements`
- `feature/dungeon-room-painter`
- `feature/add-sprite-animations`
**Rules:**
- Branch from: `develop`
- Merge back to: `develop`
- Lifetime: Delete after merge
- Naming: Use kebab-case, be descriptive but concise
**Workflow:**
```bash
# Create feature branch
git checkout develop
git pull origin develop
git checkout -b feature/my-feature
# Work on feature
git add .
git commit -m "feat: add new feature"
# Keep up to date with develop
git fetch origin
git rebase origin/develop
# Push and create PR
git push -u origin feature/my-feature
```

- Ensure tests pass
2. **Create release branch**
```bash
git checkout -b release/v0.3.2
```
3. **Follow steps 2-7 above**
## Long-Running Feature Branches
For large features (e.g., v0.4.0 modernization), use a **feature branch with sub-branches**:
```
develop
└── feature/v0.4.0-modernization (long-running)
├── feature/v0.4.0-sdl3-core
├── feature/v0.4.0-sdl3-graphics
└── feature/v0.4.0-sdl3-audio
```
**Rules:**
- Long-running branch stays alive during development
- Sub-branches merge to long-running branch
- Long-running branch periodically rebases on `develop`
- Final merge to `develop` when complete
## Tagging Strategy
### Release Tags
- Format: `v<MAJOR>.<MINOR>.<PATCH>[-prerelease]`
- Examples: `v0.3.2`, `v0.4.0-rc.1`, `v1.0.0`
- Annotated tags with release notes
### Internal Milestones
- Format: `milestone/<name>`
- Examples: `milestone/canvas-refactor-complete`
- Used for tracking major internal achievements
## Best Practices
### DO
- Keep commits atomic and focused
- Write descriptive commit messages
- Rebase feature branches on develop regularly
- Run tests before pushing
- Update documentation with code changes
- Delete branches after merging
### DON'T ❌
- Commit directly to master or develop
- Force push to shared branches
- Mix unrelated changes in one commit
- Merge without PR review
- Leave stale branches
## Quick Reference
```bash
# Start new feature
git checkout develop
git pull
git checkout -b feature/my-feature
# Update feature branch with latest develop
git fetch origin
git rebase origin/develop
# Finish feature
git push -u origin feature/my-feature
# Create PR on GitHub → Merge → Delete branch
# Start hotfix
git checkout master
git pull
git checkout -b hotfix/v0.3.3-fix
# ... fix, commit, merge to master and develop ...
# Create release
git checkout develop
git pull
git checkout -b release/v0.4.0
# ... prepare, merge to master, tag, merge back to develop ...
```
## Emergency Procedures
### If master is broken
1. Create hotfix branch immediately
2. Fix critical issue
3. Fast-track PR review
4. Hotfix deploy ASAP
### If develop is broken
1. Identify breaking commit
2. Revert if needed
3. Fix in new branch
4. Merge fix with priority
### If release needs to be rolled back
1. Tag current state as `v0.x.y-broken`
2. Revert master to previous tag
3. Create hotfix branch
4. Fix and release as patch version
---
## Current Simplified Workflow (Pre-1.0)
### Daily Development Pattern
```bash
# For documentation or small changes
git checkout master # or develop, your choice
git pull
# ... make changes ...
git add docs/
git commit -m "docs: update workflow guide"
git push origin master
# For experimental features
git checkout -b feature/my-experiment
# ... experiment ...
git push -u origin feature/my-experiment
# If it works: merge to develop
# If it doesn't: delete branch, no harm done
```
### When to Use Branches (Pre-1.0)
**Use a branch for:**
- Large refactors that might break things
- Experimenting with new ideas
- Features that take multiple days
- SDL3 migration or other big changes
**Don't bother with branches for:**
- Documentation updates
- Small bug fixes
- Typo corrections
- README updates
- Adding comments or tests
### Current Branch Usage
For now, treat `master` and `develop` interchangeably:
- `master`: Latest stable-ish code + docs
- `develop`: Optional staging area for integration
When you want docs public, just push to `master`. The GitHub Pages / docs site will update automatically.
### Commit Message (Simplified)
Still try to follow the convention, but don't stress:
```bash
# Good enough
git commit -m "docs: reorganize documentation structure"
git commit -m "fix: dungeon editor crash on load"
git commit -m "feat: add overworld sprite editor"
# Also fine for now
git commit -m "update docs"
git commit -m "fix crash"
```
### Releases (Pre-1.0)
Just tag and push:
```bash
# When you're ready for v0.3.2
git tag -a v0.3.2 -m "Release v0.3.2"
git push origin v0.3.2
# GitHub Actions builds it automatically
```
No need for release branches or complex merging until you have multiple contributors.

### Fallback Mechanisms
#### vcpkg Fallback
```yaml
# Primary: vcpkg installation
- name: Set up vcpkg (Windows)
continue-on-error: true
# Fallback: Manual dependency installation
- name: Install dependencies manually (Windows fallback)
if: steps.vcpkg_setup.outcome == 'failure'
```
#### Chocolatey Integration
```yaml
# Install Chocolatey if not present
if (-not (Get-Command choco -ErrorAction SilentlyContinue)) {
# Install Chocolatey
}
# Install dependencies via Chocolatey
choco install -y cmake ninja git python3
```
#### Build Configuration Fallback
```yaml
# Primary: Full build with vcpkg
cmake -DCMAKE_TOOLCHAIN_FILE="vcpkg.cmake" -DYAZE_MINIMAL_BUILD=OFF

# B5 - Architecture and Networking
This document provides a comprehensive overview of the yaze application's architecture, focusing on its service-oriented design, gRPC integration, and real-time collaboration features.
## 1. High-Level Architecture
The yaze ecosystem is split into two main components: the **YAZE GUI Application** and the **`z3ed` CLI Tool**.
```
┌─────────────────────────────────────────────────────────────────────────┐
│ YAZE GUI Application │
│ (Runs on local machine) │
├─────────────────────────────────────────────────────────────────────────┤
│ │
│ ┌─────────────────────────────────────────────────────────────┐ │
│ │ UnifiedGRPCServer (Port 50051) │ │
│ │ ════════════════════════════════════════════════════════ │ │
│ │ Hosts 3 gRPC Services on a SINGLE PORT: │ │
│ │ │ │
│ │ 1. ImGuiTestHarness Service │ │
│ │ • GUI automation (click, type, wait, assert) │ │
│ │ │ │
│ │ 2. RomService │ │
│ │ • Read/write ROM bytes │ │
│ │ • Proposal system for collaborative editing │ │
│ │ │ │
│ │ 3. CanvasAutomation Service │ │
│ │ • High-level canvas operations (tile ops, selection) │ │
│ └─────────────────────────────────────────────────────────────┘ │
│ ↑ │
│ │ gRPC Connection │
└────────────────────────────────────┼──────────────────────────────────────┘
│
↓
┌────────────────────────────────────┼──────────────────────────────────────┐
│ z3ed CLI Tool │
│ (Command-line interface) │
├─────────────────────────────────────────────────────────────────────────┤
│ ┌──────────────────────────────────────────────────────────────┐ │
│ │ CLI Services (Business Logic - NOT gRPC servers) │ │
│ │ ══════════════════════════════════════════════════ │ │
│ │ - AI Services (Gemini, Ollama) │ │
│ │ - Agent Services (Chat, Tool Dispatcher) │ │
│ │ - Network Clients (gRPC and WebSocket clients) │ │
│ └──────────────────────────────────────────────────────────────┘ │
└───────────────────────────────────────────────────────────────────────────┘
```
## 2. Service Taxonomy
It's important to distinguish between the two types of "services" in the yaze project.
### APP Services (gRPC Servers)
- **Location**: `src/app/core/service/`, `src/app/net/`
- **Runs In**: YAZE GUI application
- **Purpose**: Expose application functionality to remote clients (like the `z3ed` CLI).
- **Type**: gRPC **SERVER** implementations.
### CLI Services (Business Logic)
- **Location**: `src/cli/service/`
- **Runs In**: `z3ed` CLI tool
- **Purpose**: Implement the business logic for the CLI commands.
- **Type**: These are helper classes, **NOT** gRPC servers. They may include gRPC **CLIENTS** to connect to the APP Services.
## 3. gRPC Services
yaze exposes its core functionality through a `UnifiedGRPCServer` that hosts multiple services on a single port (typically 50051).
### ImGuiTestHarness Service
- **Proto**: `imgui_test_harness.proto`
- **Purpose**: GUI automation.
- **Features**: Click, type, screenshots, widget discovery.
### RomService
- **Proto**: `rom_service.proto`
- **Purpose**: Low-level ROM manipulation.
- **Features**: Read/write bytes, proposal system for collaborative editing, snapshots for version management.
### CanvasAutomation Service
- **Proto**: `canvas_automation.proto`
- **Purpose**: High-level, abstracted control over canvas-based editors.
- **Features**: Tile operations (get/set), selection management, view control (pan/zoom).
## 4. Real-Time Collaboration
Real-time collaboration is enabled through a WebSocket-based protocol managed by the `yaze-server`, a separate Node.js application.
### Architecture
```
┌─────────────┐ WebSocket ┌──────────────┐
│ yaze app │◄────────────────────────────►│ yaze-server │
│ (GUI) │ │ (Node.js) │
└─────────────┘ └──────────────┘
▲ ▲
│ gRPC │ WebSocket
└─────────────┐ │
┌──────▼──────┐ │
│ z3ed CLI │◄──────────────────────┘
└─────────────┘
```
### Core Components
- **ROM Version Manager**: Protects the ROM from corruption with snapshots and safe points.
- **Proposal Approval Manager**: Manages a collaborative voting system for applying changes.
- **Collaboration Panel**: A UI within the YAZE editor for managing collaboration.
### WebSocket Protocol
The WebSocket protocol handles real-time messaging for:
- Hosting and joining sessions.
- Broadcasting ROM diffs (`rom_sync`).
- Sharing and voting on proposals (`proposal_share`, `proposal_vote`).
- Sharing snapshots.
## 5. Data Flow Example: AI Agent Edits a Tile
1. **User** runs `z3ed agent --prompt "Paint grass at 10,10"`.
2. The **GeminiAIService** (a CLI Service) parses the prompt and returns a tool call to `overworld-set-tile`.
3. The **ToolDispatcher** (a CLI Service) routes this to the appropriate handler.
4. The **Tile16ProposalGenerator** (a CLI Service) creates a proposal.
5. The **GuiAutomationClient** (a CLI Service acting as a gRPC client) calls the `CanvasAutomation.SetTile()` RPC method on the YAZE application's `UnifiedGRPCServer`.
6. The **CanvasAutomationService** in the YAZE app receives the request and uses the `CanvasAutomationAPI` to paint the tile.
7. If collaboration is active, the change is submitted through the **ProposalApprovalManager**, which communicates with the `yaze-server` via WebSocket to manage voting.
8. Once approved, the change is applied to the ROM and synced with all collaborators.

YAZE `zelda3` Library Refactoring & Migration Plan
Author: Gemini
Date: 2025-10-11
Status: Proposed
1. Introduction & Motivation
The zelda3 library, currently located at src/app/zelda3, encapsulates all the data models and logic specific to "A Link
to the Past." It serves as the foundational data layer for both the yaze GUI application and the z3ed command-line tool.
Its current structure and location present two primary challenges:
1. Monolithic Design: Like the gfx and gui libraries, zelda3 is a single, large static library. This creates a
tightly-coupled module where a change to any single component (e.g., dungeon objects) forces a relink of the entire
library and all its dependents.
2. Incorrect Location: The library resides within src/app/, which is designated for the GUI application's specific code.
However, its logic is shared with the cli target. This violates architectural principles and creates an improper
dependency from the cli module into the app module's subdirectory.
This document proposes a comprehensive plan to both refactor the zelda3 library into logical sub-modules and migrate it
to a top-level directory (src/zelda3) to correctly establish it as a shared, core component.
2. Goals
* Establish as a Core Shared Library: Physically and logically move the library to src/zelda3 to reflect its role as a
foundational component for both the application and the CLI.
* Improve Incremental Build Times: Decompose the library into smaller, focused modules to minimize the scope of rebuilds
and relinks.
* Clarify Domain Boundaries: Create a clear separation between the major game systems (Overworld, Dungeon, Sprites, etc.)
to improve code organization and maintainability.
* Isolate Legacy Code: Encapsulate the legacy Hyrule Magic music tracker code into its own module to separate it from the
modern C++ codebase.
3. Proposed Architecture
The zelda3 library will be moved to src/zelda3/ and broken down into six distinct, layered libraries.

```
3.1. zelda3_core (Foundation)
* Responsibility: Contains fundamental data structures, constants, and labels used across all other zelda3 modules.
* Contents: common.h, zelda3_labels.h/.cc, dungeon/dungeon_rom_addresses.h.
* Dependencies: yaze_util.
3.2. zelda3_sprite (Shared Game Entity)
* Responsibility: Manages the logic and data for sprites, which are used in both dungeons and the overworld.
* Contents: sprite/sprite.h/.cc, sprite/sprite_builder.h/.cc, sprite/overlord.h.
* Dependencies: zelda3_core.
3.3. zelda3_dungeon (Dungeon System)
* Responsibility: The complete, self-contained system for all dungeon-related data and logic.
* Contents: All files from dungeon/ (room.h/.cc, room_object.h/.cc, dungeon_editor_system.h/.cc, etc.).
* Dependencies: zelda3_core, zelda3_sprite.
3.4. zelda3_overworld (Overworld System)
* Responsibility: The complete, self-contained system for all overworld-related data and logic.
* Contents: All files from overworld/ (overworld.h/.cc, overworld_map.h/.cc, etc.).
* Dependencies: zelda3_core, zelda3_sprite.
3.5. zelda3_screen (Specific Game Screens)
* Responsibility: High-level components representing specific, non-gameplay screens.
* Contents: All files from screen/ (dungeon_map.h/.cc, inventory.h/.cc, title_screen.h/.cc).
* Dependencies: zelda3_dungeon, zelda3_overworld.
3.6. zelda3_music (Legacy Isolation)
* Responsibility: Encapsulates the legacy Hyrule Magic music tracker code.
* Contents: music/tracker.h/.cc.
* Dependencies: zelda3_core.
4. Migration Plan
This plan details the steps to move the library from src/app/zelda3 to src/zelda3.
1. Physical File Move:
* Move the directory /Users/scawful/Code/yaze/src/app/zelda3 to /Users/scawful/Code/yaze/src/zelda3.
2. Update CMake Configuration:
* In src/CMakeLists.txt, change the line include(zelda3/zelda3_library.cmake) to
include(zelda3/zelda3_library.cmake).
* In the newly moved src/zelda3/zelda3_library.cmake, update all target_include_directories paths to remove the app/
prefix (e.g., change ${CMAKE_SOURCE_DIR}/src/app to ${CMAKE_SOURCE_DIR}/src).
3. Update Include Directives (Global):
* Perform a project-wide search-and-replace for all occurrences of #include "zelda3/ and change them to #include
"zelda3/.
* This will be the most extensive step, touching files in src/app/, src/cli/, and test/.
4. Verification:
* After the changes, run a full CMake configure and build (cmake --preset mac-dev -B build_ai && cmake --build
build_ai) to ensure all paths are correctly resolved and the project compiles successfully.
5. Implementation Plan (CMake)
The refactoring will be implemented within the new src/zelda3/zelda3_library.cmake file.
1. Define Source Groups: Create set() commands for each new library (ZELDA3_CORE_SRC, ZELDA3_DUNGEON_SRC, etc.).
2. Create Static Libraries: Use add_library(yaze_zelda3_core STATIC ...) for each module.
3. Establish Link Dependencies: Use target_link_libraries to define the dependencies outlined in section 3.
4. Create Aggregate Interface Library: The yaze_zelda3 target will be converted to an INTERFACE library that links against
all the new sub-libraries, providing a single, convenient link target for yaze_gui, yaze_cli, and the test suites.
6. Expected Outcomes
This refactoring and migration will establish the zelda3 library as a true core component of the application. The result
will be a more logical and maintainable architecture, significantly faster incremental build times, and a clear
separation of concerns that will benefit future development.

# B7 - Architecture Refactoring Plan
**Date**: October 15, 2025
**Status**: Proposed
**Author**: Gemini AI Assistant
## 1. Overview & Goals
This document outlines a comprehensive refactoring plan for the YAZE architecture. The current structure has resulted in tight coupling between components, slow incremental build times, and architectural inconsistencies (e.g., shared libraries located within the `app/` directory).
The primary goals of this refactoring are:
1. **Establish a Clear, Layered Architecture**: Separate foundational libraries (`core`, `gfx`, `zelda3`) from the applications that consume them (`app`, `cli`).
2. **Improve Modularity & Maintainability**: Decompose large, monolithic libraries into smaller, single-responsibility modules.
3. **Drastically Reduce Build Times**: Minimize rebuild cascades by ensuring changes in one module do not trigger unnecessary rebuilds in unrelated components.
4. **Enable Future Development**: Create a flexible foundation for new features like alternative rendering backends (SDL3, Metal, Vulkan) and a fully-featured CLI.
## 2. Proposed Target Architecture
The proposed architecture organizes the codebase into two distinct layers: **Foundational Libraries** and **Applications**.
```
/src
├── core/ (NEW) 📖 Project model, Asar wrapper, etc.
├── gfx/ (MOVED) 🎨 Graphics engine, backends, resource management
├── zelda3/ (MOVED) Game Game-specific data models and logic
├── util/ (EXISTING) Low-level utilities (logging, file I/O)
│
├── app/ (REFACTORED) Main GUI Application
│ ├── controller.cc (MOVED) Main application controller
│ ├── platform/ (MOVED) Windowing, input, platform abstractions
│ ├── service/ (MOVED) AI gRPC services for automation
│ ├── editor/ (EXISTING) 🎨 Editor implementations
│ └── gui/ (EXISTING) Shared ImGui widgets
│
└── cli/ (EXISTING) z3ed Command-Line Tool
```
## 3. Detailed Refactoring Plan
This plan will be executed in three main phases.
### Phase 1: Create `yaze_core_lib` (Project & Asar Logic)
This phase establishes a new, top-level library for application-agnostic project management and ROM patching logic.
1. **Create New Directory**: Create `src/core/`.
2. **Move Files**:
* Move `src/app/core/{project.h, project.cc}` → `src/core/` (pending)
* Move `src/app/core/{asar_wrapper.h, asar_wrapper.cc}` → `src/core/` (done)
* Move `src/app/core/features.h` → `src/core/` (pending)
3. **Update Namespace**: In the moved files, change the namespace from `yaze::core` to `yaze::project` for clarity.
4. **Create CMake Target**: In a new `src/core/CMakeLists.txt`, define the `yaze_core_lib` static library containing the moved files. This library should have minimal dependencies (e.g., `yaze_util`, `absl`).
### Phase 2: Elevate `yaze_gfx_lib` (Graphics Engine)
This phase decouples the graphics engine from the GUI application, turning it into a foundational, reusable library. This is critical for supporting multiple rendering backends as outlined in `docs/G2-renderer-migration-plan.md`.
1. **Move Directory**: Move the entire `src/app/gfx/` directory to `src/gfx/`.
2. **Create CMake Target**: In a new `src/gfx/CMakeLists.txt`, define the `yaze_gfx_lib` static library. This will aggregate all graphics components (`backend`, `core`, `resource`, etc.).
3. **Update Dependencies**: The `yaze` application target will now explicitly depend on `yaze_gfx_lib`.
### Phase 3: Streamline the `app` Layer
This phase dissolves the ambiguous `src/app/core` directory and simplifies the application's structure.
1. **Move Service Layer**: Move the `src/app/core/service/` directory to `src/app/service/`. This creates a clear, top-level service layer for gRPC implementations.
2. **Move Platform Code**: Move `src/app/core/{window.cc, window.h, timing.h}` into the existing `src/app/platform/` directory. This consolidates all platform-specific windowing and input code.
3. **Elevate Main Controller**: Move `src/app/core/{controller.cc, controller.h}` to `src/app/`. This highlights its role as the primary orchestrator of the GUI application.
4. **Update CMake**:
* Eliminate the `yaze_app_core_lib` target.
* Add the source files from the moved directories (`app/controller.cc`, `app/platform/window.cc`, `app/service/*.cc`, etc.) directly to the main `yaze` executable target.
## 4. Alignment with EditorManager Refactoring
This architectural refactoring fully supports and complements the ongoing `EditorManager` improvements detailed in `docs/H2-editor-manager-architecture.md`.
- The `EditorManager` and its new coordinators (`UICoordinator`, `PopupManager`, `SessionCoordinator`) are clearly components of the **Application Layer**.
- By moving the foundational libraries (`core`, `gfx`) out of `src/app`, we create a clean boundary. The `EditorManager` and its helpers will reside within `src/app/editor/` and `src/app/editor/system/`, and will consume the new `yaze_core_lib` and `yaze_gfx_lib` as dependencies.
- This separation makes the `EditorManager`'s role as a UI and session coordinator even clearer, as it no longer lives alongside low-level libraries.
## 5. Migration Checklist
1. [x] **Phase 1**: Create `src/core/` and move `project`, `asar_wrapper`, and `features` files.
2. [x] **Phase 1**: Create the `yaze_core_lib` CMake target.
3. [ ] **Phase 2**: Move `src/app/gfx/` to `src/gfx/`. (DEFERRED - app-specific)
4. [ ] **Phase 2**: Create the `yaze_gfx_lib` CMake target. (DEFERRED - app-specific)
5. [x] **Phase 3**: Move `src/app/core/service/` to `src/app/service/`.
6. [x] **Phase 3**: Move `src/app/core/testing/` to `src/app/test/` (merged with existing test/).
7. [x] **Phase 3**: Move `window.cc`, `timing.h` to `src/app/platform/`.
8. [x] **Phase 3**: Move `controller.cc` to `src/app/`.
9. [x] **Phase 3**: Update CMake targets - renamed `yaze_core_lib` to `yaze_app_core_lib` to distinguish from foundational `yaze_core_lib`.
10. [x] **Phase 3**: `src/app/core/` now only contains `core_library.cmake` for app-level functionality.
11. [x] **Cleanup**: All `#include "app/core/..."` directives updated to new paths.
## 6. Completed Changes (October 15, 2025)
### Phase 1: Foundational Core Library ✅
- Created `src/core/` with `project.{h,cc}`, `features.h`, and `asar_wrapper.{h,cc}`
- Changed namespace from `yaze::core` to `yaze::project` for project management types
- Created new `yaze_core_lib` in `src/core/CMakeLists.txt` with minimal dependencies
- Updated all 32+ files to use `#include "core/project.h"` and `#include "core/features.h"`
### Phase 3: Application Layer Streamlining ✅
- Moved `src/app/core/service/` → `src/app/service/` (gRPC services)
- Moved `src/app/core/testing/` → `src/app/test/` (merged with existing test infrastructure)
- Moved `src/app/core/window.{cc,h}`, `timing.h` → `src/app/platform/`
- Moved `src/app/core/controller.{cc,h}` → `src/app/`
- Renamed old `yaze_core_lib` to `yaze_app_core_lib` to avoid naming conflict
- Updated all CMake dependencies in editor, emulator, agent, and test libraries
- Removed duplicate source files from `src/app/core/`
### Deferred (Phase 2)
Graphics refactoring (`src/app/gfx/` → `src/gfx/`) deferred as it's app-specific and requires careful consideration of rendering backends.
## 6. Expected Benefits
- **Faster Builds**: Incremental build times are expected to decrease by **40-60%** as changes will be localized to smaller libraries.
- **Improved Maintainability**: A clear, layered architecture makes the codebase easier to understand, navigate, and extend.
- **True CLI Decoupling**: The `z3ed` CLI can link against `yaze_core_lib` and `yaze_zelda3_lib` without pulling in any GUI or rendering dependencies, resulting in a smaller, more portable executable.
- **Future-Proofing**: The abstracted `gfx` library paves the way for supporting SDL3, Metal, or Vulkan backends with minimal disruption to the rest of the application.

# Testing z3ed Without ROM Files
**Last Updated:** October 10, 2025
**Status:** Active
## Overview
The `z3ed` AI agent now supports **mock ROM mode** for testing without requiring actual ROM files. This is essential for:
- **CI/CD pipelines** - No ROM files can be committed to GitHub
- **Development testing** - Quick iterations without ROM dependencies
- **Contributors** - Test the agent without needing to provide ROMs
- **Automated testing** - Consistent, reproducible test environments
## How Mock ROM Mode Works
Mock ROM mode creates a minimal but valid ROM structure with:
- Proper SNES header (LoROM mapping, 1MB size)
- Zelda3 embedded labels (rooms, sprites, entrances, items, music, etc.)
- Resource label manager initialization
- No actual ROM data (tiles, graphics, maps remain empty)
This allows the AI agent to:
- Answer questions about room names, sprite IDs, entrance numbers
- Lookup labels and constants
- Test function calling and tool dispatch
- Validate agent logic without game data
## Usage
### Command Line Flag
Add `--mock-rom` to any `z3ed agent` command:
```bash
# Simple chat with mock ROM
z3ed agent simple-chat "What is room 5?" --mock-rom
# Test conversation with mock ROM
z3ed agent test-conversation --mock-rom
# AI provider testing
z3ed agent simple-chat "List all dungeons" --mock-rom --ai_provider=ollama
```
### Test Suite
The `agent_test_suite.sh` script now defaults to mock ROM mode:
```bash
# Run tests with mock ROM (default)
./scripts/agent_test_suite.sh ollama
# Or with Gemini
./scripts/agent_test_suite.sh gemini
```
To use a real ROM instead, edit the script:
```bash
USE_MOCK_ROM=false # At the top of agent_test_suite.sh
```
## What Works with Mock ROM
### Fully Supported
**Label Queries:**
- "What is room 5?" → "Tower of Hera - Moldorm Boss"
- "What sprites are in the game?" → Lists all 256 sprite names
- "What is entrance 0?" → "Link's House Main"
- "List all items" → Bow, Boomerang, Hookshot, etc.
**Resource Lookups:**
- Room names (296 rooms)
- Entrance names (133 entrances)
- Sprite names (256 sprites)
- Overlord names (14 overlords)
- Overworld map names (160 maps)
- Item names
- Music track names
- Graphics sheet names
**AI Testing:**
- Function calling / tool dispatch
- Natural language understanding
- Error handling
- Tool output parsing
- Multi-turn conversations
### Limited Support
**Queries Requiring Data:**
- "What tiles are used in room 5?" → No tile data in mock ROM
- "Show me the palette for map 0" → No palette data
- "What's at coordinate X,Y?" → No map data
- "Export graphics from dungeon 1" → No graphics data
These queries will either return empty results or errors indicating no ROM data is available.
### Not Supported
**Operations That Modify ROM:**
- Editing tiles
- Changing palettes
- Modifying sprites
- Patching ROM data
## Testing Strategy
### For Agent Logic
Use **mock ROM** for testing:
- Function calling mechanisms
- Tool dispatch and routing
- Natural language understanding
- Error handling
- Label resolution
- Resource lookups
### For ROM Operations
Use **real ROM** for testing:
- Tile editing
- Graphics manipulation
- Palette modifications
- Data extraction
- ROM patching
## CI/CD Integration
### GitHub Actions Example
```yaml
name: Test z3ed Agent
on: [push, pull_request]
jobs:
test-agent:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Install Dependencies
run: |
# Install ollama if testing local models
curl -fsSL https://ollama.ai/install.sh | sh
ollama pull qwen2.5-coder
- name: Build z3ed
run: |
cmake -B build_test
cmake --build build_test --parallel
- name: Run Agent Tests (Mock ROM)
run: |
./scripts/agent_test_suite.sh ollama
env:
# Or use Gemini with API key
GEMINI_API_KEY: ${{ secrets.GEMINI_API_KEY }}
```
## Embedded Labels Reference
Mock ROM includes all these labels from `zelda3::Zelda3Labels`:
| Resource Type | Count | Example |
|--------------|-------|---------|
| Rooms | 296 | "Sewer - Throne Room" |
| Entrances | 133 | "Link's House Main" |
| Sprites | 256 | "Moldorm (Boss)" |
| Overlords | 14 | "Overlord - Agahnim's Barrier" |
| Overworld Maps | 160 | "Light World - Hyrule Castle" |
| Items | 64+ | "Bow", "Boomerang", "Hookshot" |
| Music Tracks | 64+ | "Title Theme", "Overworld", "Dark World" |
| Graphics Sheets | 128+ | "Link Sprites", "Enemy Pack 1" |
See `src/zelda3/zelda3_labels.h` for the complete list.
## Troubleshooting
### "No ROM loaded" error
Make sure you're using the `--mock-rom` flag:
```bash
# Wrong
z3ed agent simple-chat "test"
# Correct
z3ed agent simple-chat "test" --mock-rom
```
### Mock ROM fails to initialize
Check the error message. Common issues:
- Build system didn't include `mock_rom.cc`
- Missing `zelda3_labels.cc` in build
- Linker errors with resource labels
### Agent returns empty/wrong results
Remember: Mock ROM has **labels only**, no actual game data.
Queries like "What tiles are in room 5?" won't work because there's no tile data.
Use queries about labels and IDs instead: "What is the name of room 5?"
## Development
### Adding New Labels
To add new label types to mock ROM:
1. **Add to `zelda3_labels.h`:**
```cpp
static const std::vector<std::string>& GetNewResourceNames();
```
2. **Implement in `zelda3_labels.cc`:**
```cpp
const std::vector<std::string>& Zelda3Labels::GetNewResourceNames() {
static std::vector<std::string> names = {"Item1", "Item2", ...};
return names;
}
```
3. **Add to `ToResourceLabels()`:**
```cpp
const auto& new_resources = GetNewResourceNames();
for (size_t i = 0; i < new_resources.size(); ++i) {
labels["new_resource"][std::to_string(i)] = new_resources[i];
}
```
4. **Rebuild:**
```bash
cmake --build build --parallel
```
### Testing Mock ROM Directly
```cpp
#include "cli/handlers/mock_rom.h"
Rom rom;
auto status = InitializeMockRom(rom);
if (status.ok()) {
// ROM is ready with all labels
auto* label_mgr = rom.resource_label();
std::string room_name = label_mgr->GetLabel("room", "5");
// room_name == "Tower of Hera - Moldorm Boss"
}
```
## Best Practices
### DO
- Use mock ROM for CI/CD and automated tests
- Use mock ROM for agent logic development
- Use mock ROM when contributing (no ROM files needed)
- Test with real ROM before releasing features
- Document which features require real ROM data
### DON'T ❌
- Commit ROM files to Git (legal issues)
- Assume mock ROM has actual game data
- Use mock ROM for testing data extraction
- Skip real ROM testing entirely

## Feature 1: Learned Knowledge Service
### What It Does
Persists information across agent sessions:
- **Preferences**: User's default settings (palette, tool choices)
- **ROM Patterns**: Learned behaviors (frequently accessed rooms, sprite patterns)
- **Project Context**: ROM-specific goals and notes
- **Conversation Memory**: Summaries of past discussions for continuity
### Integration Status: Complete
**Files**:
- `cli/service/agent/learned_knowledge_service.{h,cc}` - Core service
- `cli/handlers/agent/general_commands.cc` - CLI handlers
- `cli/handlers/agent.cc` - Routing
### Usage Examples
```bash
# Save preference
z3ed agent learn --preference default_palette=2
# Get preference
z3ed agent learn --get-preference default_palette
# Save project context
z3ed agent learn --project "myrom" --context "Vanilla+ difficulty hack"
# Get project details
z3ed agent learn --get-project "myrom"
# Search past conversations
z3ed agent learn --search-memories "dungeon room 5"
# Export all learned data
z3ed agent learn --export learned_data.json
# View statistics
z3ed agent learn --stats
```
### AI Agent Integration
The ConversationalAgentService now:
1. Initializes `LearnedKnowledgeService` on startup
2. Can inject learned context into prompts (when `inject_learned_context_=true`)
3. Can access preferences/patterns/memories during tool execution
**API**:
```cpp
ConversationalAgentService service;
service.learned_knowledge().SetPreference("palette", "2");
auto pref = service.learned_knowledge().GetPreference("palette");
```
### Data Persistence
**Location**: `~/.yaze/agent/`
**Format**: JSON
**Files**:
- `preferences.json` - Key-value pairs
- `patterns.json` - Timestamped ROM patterns with confidence scores
- `projects.json` - Project metadata and context
- `memories.json` - Conversation summaries (last 100)
### Current Integration
- `cli/service/agent/learned_knowledge_service.{h,cc}` is constructed inside `ConversationalAgentService`.
- CLI commands such as `z3ed agent learn …` and `agent recall …` exercise this API.
- JSON artifacts persist under `~/.yaze/agent/`.
## Feature 2: TODO Management System
### What It Does
Enables AI agents to break down complex tasks into executable steps with dependency tracking and prioritization.
### Current Integration
- Core service in `cli/service/agent/todo_manager.{h,cc}`.
- CLI routing in `cli/handlers/agent/todo_commands.{h,cc}` and `cli/handlers/agent.cc`.
- JSON storage at `~/.yaze/agent/todos.json`.
### Usage Examples
```bash
# Create TODO
z3ed agent todo create "Fix input handling" --category=emulator --priority=1
# List TODOs
z3ed agent todo list
# Filter by status
z3ed agent todo list --status=in_progress
# Update status
z3ed agent todo update 1 --status=completed
# Get next actionable task
z3ed agent todo next
# Generate dependency-aware execution plan
z3ed agent todo plan
# Clear completed
z3ed agent todo clear-completed
```
### AI Agent Integration
```cpp
ConversationalAgentService service;
service.todo_manager().CreateTodo("Debug A button", "emulator", 1);
auto next = service.todo_manager().GetNextActionableTodo();
```
### Storage
**Location**: `~/.yaze/agent/todos.json`
**Format**: JSON array with dependencies:
```json
{
"todos": [
{
"id": "1",
"description": "Debug input handling",
"status": "in_progress",
"category": "emulator",
"priority": 1,
"dependencies": [],
"tools_needed": ["emulator-set-breakpoint", "emulator-read-memory"]
}
]
}
```
## Feature 3: Advanced Routing
### What It Does
Optimizes tool responses for AI consumption with:
- **Data type inference** (sprite data vs tile data vs palette)
- **Pattern extraction** (repeating values, structures)
- **Structured summaries** (high-level + detailed + next steps)
- **GUI action generation** (converts analysis → automation script)
### Status
- Implementation lives in `cli/service/agent/advanced_routing.{h,cc}` and is compiled via `cli/agent.cmake`.
- Hook-ups to `ToolDispatcher` / `ConversationalAgentService` remain on the backlog.
### How to Integrate
**Option 1: In ToolDispatcher (Automatic)**
```cpp
// In tool_dispatcher.cc, after tool execution:
auto result = handler->Run(args, rom_context_);
if (result.ok()) {
std::string output = output_buffer.str();
// Route through advanced router for enhanced response
AdvancedRouter::RouteContext ctx;
ctx.rom = rom_context_;
ctx.tool_calls_made = {call.tool_name};
if (call.tool_name == "hex-read") {
auto routed = AdvancedRouter::RouteHexAnalysis(data, address, ctx);
return absl::StrCat(routed.summary, "\n\n", routed.detailed_data);
}
return output;
}
```
**Option 2: In ConversationalAgentService (Selective)**
```cpp
// After getting tool results, enhance the response:
ChatMessage ConversationalAgentService::EnhanceResponse(
const ChatMessage& response,
const std::string& user_message) {
AdvancedRouter::RouteContext ctx;
ctx.rom = rom_context_;
ctx.user_intent = user_message;
// Use advanced router to synthesize multi-tool responses
auto routed = AdvancedRouter::SynthesizeMultiToolResponse(
tool_results_, ctx);
ChatMessage enhanced = response;
enhanced.message = routed.summary;
// Attach routed.gui_actions as metadata
return enhanced;
}
```
## Feature 4: Agent Pretraining
### What It Does
Injects structured knowledge into the agent's first message to teach it about:
- ROM structure (memory map, data formats)
- Hex analysis patterns (how to recognize sprites, tiles, palettes)
- Map editing workflows (tile placement, warp creation)
- Tool usage best practices
### Status
- Pretraining scaffolding (`cli/service/agent/agent_pretraining.{h,cc}`) builds today.
- The one-time injection step in `ConversationalAgentService` is still disabled.
### How to Integrate
**In ConversationalAgentService::SendMessage()**:
```cpp
absl::StatusOr<ChatMessage> ConversationalAgentService::SendMessage(
const std::string& message) {
// One-time pretraining injection on first message
if (inject_pretraining_ && !pretraining_injected_ && rom_context_) {
std::string pretraining = AgentPretraining::GeneratePretrainingPrompt(rom_context_);
ChatMessage pretraining_msg;
pretraining_msg.sender = ChatMessage::Sender::kUser;
pretraining_msg.message = pretraining;
pretraining_msg.is_internal = true; // Don't show to user
history_.insert(history_.begin(), pretraining_msg);
pretraining_injected_ = true;
}
// Continue with normal message processing...
}
```
### Knowledge Modules
```cpp
auto modules = AgentPretraining::GetModules();
for (const auto& module : modules) {
std::cout << "Module: " << module.name << std::endl;
std::cout << "Required: " << (module.required ? "Yes" : "No") << std::endl;
std::cout << module.content << std::endl;
}
```
Modules include:
- `rom_structure` - Memory map, data formats
- `hex_analysis` - Pattern recognition for sprites/tiles/palettes
- `map_editing` - Overworld/dungeon editing workflows
- `tool_usage` - Best practices for tool calling
## Feature 5: Agent Handoff
Handoff covers CLI ↔ GUI transfers, specialised agent delegation, and human/AI ownership changes. The proposed `HandoffContext` structure (see code listing earlier) captures conversation history, ROM state, TODOs, and transient tool data. Serialization, cross-surface loading, and persona-specific workflows remain unimplemented.
## Current Integration Snapshot
Integrated components:
- Learned knowledge service (`cli/service/agent/learned_knowledge_service.{h,cc}`) with CLI commands and JSON persistence under `~/.yaze/agent/`.
- TODO manager (`cli/service/agent/todo_manager.{h,cc}` plus CLI handlers) with storage at `~/.yaze/agent/todos.json`.
- Emulator debugging gRPC service; 20 of 24 methods are implemented (see `E9-ai-agent-debugging-guide.md`).
Pending integration:
- Advanced router (`cli/service/agent/advanced_routing.{h,cc}`) needs wiring into `ToolDispatcher` or `ConversationalAgentService`.
- Agent pretraining (`cli/service/agent/agent_pretraining.{h,cc}`) needs the one-time injection path enabled.
- Handoff serialization and import/export tooling are still design-only.

# z3ed Command Abstraction Layer Guide
**Created**: October 11, 2025
**Status**: Implementation Complete
## Overview
This guide documents the new command abstraction layer for z3ed CLI commands. The abstraction layer eliminates ~500+ lines of duplicated code across tool commands and provides a consistent, maintainable architecture for future command development.
## Problem Statement
### Before Abstraction
The original `tool_commands.cc` (1549 lines) had severe code duplication:
1. **ROM Loading**: Every command had 20-30 lines of identical ROM loading logic
2. **Argument Parsing**: Each command manually parsed `--format`, `--rom`, `--type`, etc.
3. **Output Formatting**: JSON vs text formatting was duplicated across every command
4. **Label Initialization**: Resource label loading was repeated in every handler
5. **Error Handling**: Inconsistent error messages and validation patterns
### Code Duplication Example
```cpp
// Repeated in EVERY command (30+ times):
Rom rom_storage;
Rom* rom = nullptr;
if (rom_context != nullptr && rom_context->is_loaded()) {
rom = rom_context;
} else {
auto rom_or = LoadRomFromFlag();
if (!rom_or.ok()) {
return rom_or.status();
}
rom_storage = std::move(rom_or.value());
rom = &rom_storage;
}
// Initialize labels (repeated in every command that needs labels)
if (rom->resource_label()) {
if (!rom->resource_label()->labels_loaded_) {
core::YazeProject project;
project.use_embedded_labels = true;
auto labels_status = project.InitializeEmbeddedLabels();
// ... more boilerplate ...
}
}
// Manual argument parsing (repeated everywhere)
std::string format = "json";
for (size_t i = 0; i < arg_vec.size(); ++i) {
const std::string& token = arg_vec[i];
if (token == "--format") {
if (i + 1 >= arg_vec.size()) {
return absl::InvalidArgumentError("--format requires a value.");
}
format = arg_vec[++i];
} else if (absl::StartsWith(token, "--format=")) {
format = token.substr(9);
}
}
// Manual output formatting (repeated everywhere)
if (format == "json") {
std::cout << "{\n";
std::cout << " \"field\": \"value\",\n";
std::cout << "}\n";
} else {
std::cout << "Field: value\n";
}
```
## Solution Architecture
### Three-Layer Abstraction
1. **CommandContext** - ROM loading, context management
2. **ArgumentParser** - Unified argument parsing
3. **OutputFormatter** - Consistent output formatting
4. **CommandHandler** (Optional) - Base class for structured commands
### File Structure
```
src/cli/service/resources/
├── command_context.h # Context management
├── command_context.cc
├── command_handler.h # Base handler class
├── command_handler.cc
└── (existing files...)
src/cli/handlers/agent/
├── tool_commands.cc # Original (to be refactored)
├── tool_commands_refactored.cc # Example refactored commands
└── (other handlers...)
```
## Core Components
### 1. CommandContext
Encapsulates ROM loading and common context:
```cpp
// Create context
CommandContext::Config config;
config.external_rom_context = rom_context; // Optional: use existing ROM
config.rom_path = "/path/to/rom.sfc"; // Optional: override ROM path
config.use_mock_rom = false; // Optional: use mock for testing
config.format = "json";
CommandContext context(config);
// Get ROM (auto-loads if needed)
ASSIGN_OR_RETURN(Rom* rom, context.GetRom());
// Ensure labels loaded
RETURN_IF_ERROR(context.EnsureLabelsLoaded(rom));
```
**Benefits**:
- Single location for ROM loading logic
- Automatic error handling
- Mock ROM support for testing
- Label management abstraction
### 2. ArgumentParser
Unified argument parsing with type safety:
```cpp
ArgumentParser parser(arg_vec);
// String arguments
auto type = parser.GetString("type"); // Returns std::optional<string>
auto format = parser.GetString("format").value_or("json");
// Integer arguments (supports hex with 0x prefix)
ASSIGN_OR_RETURN(int room_id, parser.GetInt("room"));
// Hex-only arguments
ASSIGN_OR_RETURN(int tile_id, parser.GetHex("tile"));
// Flags
if (parser.HasFlag("verbose")) {
// ...
}
// Validation
RETURN_IF_ERROR(parser.RequireArgs({"type", "query"}));
```
**Benefits**:
- Consistent argument parsing across all commands
- Type-safe with proper error handling
- Supports both `--arg=value` and `--arg value` forms
- Built-in hex parsing for ROM addresses
### 3. OutputFormatter
Consistent JSON/text output:
```cpp
ASSIGN_OR_RETURN(auto formatter, OutputFormatter::FromString("json"));
formatter.BeginObject("Room Information");
formatter.AddField("room_id", "0x12");
formatter.AddHexField("address", 0x1234, 4); // Formats as "0x1234"
formatter.AddField("sprite_count", 5);
formatter.BeginArray("sprites");
formatter.AddArrayItem("Sprite 1");
formatter.AddArrayItem("Sprite 2");
formatter.EndArray();
formatter.EndObject();
formatter.Print();
```
**Output (JSON)**:
```json
{
"room_id": "0x12",
"address": "0x1234",
"sprite_count": 5,
"sprites": [
"Sprite 1",
"Sprite 2"
]
}
```
**Output (Text)**:
```
=== Room Information ===
room_id : 0x12
address : 0x1234
sprite_count : 5
sprites:
- Sprite 1
- Sprite 2
```
**Benefits**:
- No manual JSON escaping
- Consistent formatting rules
- Easy to switch between JSON and text
- Proper indentation handling
### 4. CommandHandler (Optional Base Class)
For more complex commands, use the base class pattern:
```cpp
class MyCommandHandler : public CommandHandler {
protected:
std::string GetUsage() const override {
return "agent my-command --required <value> [--format <json|text>]";
}
absl::Status ValidateArgs(const ArgumentParser& parser) override {
return parser.RequireArgs({"required"});
}
absl::Status Execute(Rom* rom, const ArgumentParser& parser,
OutputFormatter& formatter) override {
auto value = parser.GetString("required").value();
// Business logic here
formatter.AddField("result", value);
return absl::OkStatus();
}
bool RequiresLabels() const override { return true; }
};
// Usage:
absl::Status HandleMyCommand(const std::vector<std::string>& args, Rom* rom) {
MyCommandHandler handler;
return handler.Run(args, rom);
}
```
**Benefits**:
- Enforces consistent structure
- Automatic context setup and teardown
- Built-in error handling
- Easy to test individual components

**Savings**: 50+ lines eliminated, clearer intent, easier to maintain
### Commands to Refactor
Priority order for refactoring (based on duplication level):
1. **High Priority** (Heavy duplication):
- `HandleResourceListCommand` - Example provided ✓
- `HandleResourceSearchCommand` - Example provided ✓
- `HandleDungeonDescribeRoomCommand` - 80 lines → ~35 lines
- `HandleOverworldDescribeMapCommand` - 100 lines → ~40 lines
- `HandleOverworldListWarpsCommand` - 120 lines → ~45 lines
2. **Medium Priority** (Moderate duplication):
- `HandleDungeonListSpritesCommand`
- `HandleOverworldFindTileCommand`
- `HandleOverworldListSpritesCommand`
- `HandleOverworldGetEntranceCommand`
- `HandleOverworldTileStatsCommand`
3. **Low Priority** (Simple commands, less duplication):

## Testing Strategy
### Unit Testing
```cpp
TEST(CommandContextTest, LoadsRomFromConfig) {
CommandContext::Config config;
config.rom_path = "test.sfc";
CommandContext context(config);
auto rom_or = context.GetRom();
ASSERT_OK(rom_or);
EXPECT_TRUE(rom_or.value()->is_loaded());
}
TEST(ArgumentParserTest, ParsesStringArguments) {
std::vector<std::string> args = {"--type=dungeon", "--format", "json"};
ArgumentParser parser(args);
EXPECT_EQ(parser.GetString("type").value(), "dungeon");
EXPECT_EQ(parser.GetString("format").value(), "json");
}
TEST(OutputFormatterTest, GeneratesValidJson) {
auto formatter = OutputFormatter::FromString("json").value();
formatter.BeginObject("Test");
formatter.AddField("key", "value");
formatter.EndObject();
std::string output = formatter.GetOutput();
EXPECT_THAT(output, HasSubstr("\"key\": \"value\""));
}
```
### Integration Testing

TEST(ResourceListCommandTest, ListsDungeons) {
std::vector<std::string> args = {"--type=dungeon", "--format=json"};
Rom rom;
rom.LoadFromFile("test.sfc");
auto status = HandleResourceListCommand(args, &rom);
EXPECT_OK(status);
}
```

# APU Timing Fix - Technical Analysis
**Branch:** `feature/apu-timing-fix`
**Date:** October 10, 2025
**Status:** Implemented - Core Timing Fixed (Minor Audio Glitches Remain)
---
## Implementation Status
**Completed:**
- Atomic `Step()` function for SPC700
- Fixed-point cycle ratio (no floating-point drift)
- Cycle budget model in APU
- Removed `bstep` mechanism from instructions.cc
- Cycle-accurate instruction implementations
- Proper branch timing (+2 cycles when taken)
- Dummy read/write cycles for MOV and RMW instructions
**Known Issues:**
- Some audio glitches/distortion during playback
- Minor timing inconsistencies under investigation
- Can be improved in future iterations
**Note:** The APU now executes correctly and music plays, but audio quality can be further refined.
## Problem Summary
The APU fails to load and play music because the SPC700 gets stuck during the initial CPU-APU handshake. This handshake uploads the sound driver from ROM to APU RAM. The timing desynchronization causes infinite loops detected by the watchdog timer.
---
## Current Implementation Analysis
### 1. **Cycle Counting System** (`spc700.cc`)
**Current Approach:**
```cpp
// In spc700.h line 87:
int last_opcode_cycles_ = 0;
// In RunOpcode() line 80:
last_opcode_cycles_ = spc700_cycles[opcode]; // Static lookup
```
**Problem:** The `spc700_cycles[]` array provides BASELINE cycle counts only. It does NOT account for:
- Addressing mode variations
- Page boundary crossings (+1 cycle)
- Branch taken vs not taken (+2 cycles if taken)
- Memory access penalties
### 2. **The `bstep` Mechanism** (`spc700.cc`)
**What is `bstep`?**
`bstep` is a "business step" counter used to spread complex multi-step instructions across multiple calls to `RunOpcode()`.
**Example from line 1108-1115 (opcode 0xCB - MOVSY dp):**
```cpp
case 0xcb: { // movsy dp
if (bstep == 0) {
adr = dp(); // Save address for bstep=1
}
if (adr == 0x00F4 && bstep == 1) {
LOG_DEBUG("SPC", "MOVSY writing Y=$%02X to F4 at PC=$%04X", Y, PC);
}
MOVSY(adr); // Use saved address
break;
}
```
The `MOVSY()` function internally increments `bstep` to track progress:
- `bstep=0`: Call `dp()` to get address
- `bstep=1`: Actually perform the write
- `bstep=2`: Reset to 0, instruction complete
**Why this is fragile:**
1. **Non-atomic execution**: An instruction takes 2-3 calls to `RunOpcode()` to complete
2. **State leakage**: If `bstep` gets out of sync, all future instructions fail
3. **Cycle accounting errors**: Cycles are consumed incrementally, not atomically
4. **Debugging nightmare**: Hard to trace when an instruction "really" executes
### 3. **APU Main Loop** (`apu.cc:73-143`)
**Current implementation:**
```cpp
void Apu::RunCycles(uint64_t master_cycles) {
const double ratio = memory_.pal_timing() ? apuCyclesPerMasterPal : apuCyclesPerMaster;
uint64_t master_delta = master_cycles - g_last_master_cycles;
g_last_master_cycles = master_cycles;
const uint64_t target_apu_cycles = cycles_ + static_cast<uint64_t>(master_delta * ratio);
while (cycles_ < target_apu_cycles) {
spc700_.RunOpcode(); // Variable cycles
int spc_cycles = spc700_.GetLastOpcodeCycles();
for (int i = 0; i < spc_cycles; ++i) {
Cycle(); // Advance DSP/timers
}
}
}
```
**Problems:**
1. **Floating-point `ratio`**: `apuCyclesPerMaster` is `double` (line 17), causing precision drift
2. **Opcode-level granularity**: Advances by opcode, not by cycle
3. **No sub-cycle accuracy**: Can't model instructions that span multiple cycles
### 4. **Floating-Point Precision** (`apu.cc:17`)
```cpp
static const double apuCyclesPerMaster = (32040 * 32) / (1364 * 262 * 60.0);
```
**Calculation:**
- Numerator: 32040 * 32 = 1,025,280
- Denominator: 1364 * 262 * 60.0 = 21,437,280
- Result: ~0.04783 (floating point)
**Problem:** Over thousands of cycles, tiny rounding errors accumulate, causing timing drift.
---
## Root Cause: Handshake Timing Failure
### The Handshake Protocol
1. **APU Ready**: SPC700 writes `$AA` to `$F4`, `$BB` to `$F5`
2. **CPU Waits**: Main CPU polls for `$BBAA`
3. **CPU Initiates**: Writes `$CC` to APU input port
4. **APU Acknowledges**: SPC700 sees `$CC`, prepares to receive
5. **Byte Transfer Loop**: CPU sends byte, waits for echo confirmation, sends next byte
### Where It Gets Stuck
The SPC700 enters an infinite loop because:
- **SPC700 is waiting** for a byte from CPU (hasn't arrived yet)
- **CPU is waiting** for acknowledgment from SPC700 (already sent, but missed)
This happens because cycle counts are off by 1-2 cycles per instruction, which accumulates over the ~500-1000 instructions in the handshake.
---
## LakeSnes Comparison Analysis
### What LakeSnes Does Right
**1. Atomic Instruction Execution (spc.c:73-93)**
```c
void spc_runOpcode(Spc* spc) {
if(spc->resetWanted) { /* handle reset */ return; }
if(spc->stopped) { spc_idleWait(spc); return; }
uint8_t opcode = spc_readOpcode(spc);
spc_doOpcode(spc, opcode); // COMPLETE instruction in one call
}
```
**Key insight:** LakeSnes executes instructions **atomically** - no `bstep`, no `step`, no state leakage.
**2. Cycle Tracking via Callbacks (spc.c:406-409)**
```c
static void spc_movsy(Spc* spc, uint16_t adr) {
spc_read(spc, adr); // Calls apu_cycle()
spc_write(spc, adr, spc->y); // Calls apu_cycle()
}
```
Every `spc_read()`, `spc_write()`, and `spc_idle()` call triggers `apu_cycle()`, which:
- Advances APU cycle counter
- Ticks DSP every 32 cycles
- Updates timers
**3. Simple Addressing Mode Functions (spc.c:189-275)**
```c
static uint16_t spc_adrDp(Spc* spc) {
return spc_readOpcode(spc) | (spc->p << 8);
}
static uint16_t spc_adrDpx(Spc* spc) {
uint16_t res = ((spc_readOpcode(spc) + spc->x) & 0xff) | (spc->p << 8);
spc_idle(spc); // Extra cycle for indexed addressing
return res;
}
```
Each memory access and idle call automatically advances cycles.
**4. APU Main Loop (apu.c:73-82)**
```c
int apu_runCycles(Apu* apu, int wantedCycles) {
int runCycles = 0;
uint32_t startCycles = apu->cycles;
while(runCycles < wantedCycles) {
spc_runOpcode(apu->spc);
runCycles += (uint32_t) (apu->cycles - startCycles);
startCycles = apu->cycles;
}
return runCycles;
}
```
**Problem:** This approach tracks cycles by **delta**, which works because every memory access calls `apu_cycle()`.
### Where LakeSnes Falls Short (And How We Can Do Better)
**1. No Explicit Cycle Return**
- LakeSnes relies on tracking `cycles` delta after each opcode
- Doesn't return precise cycle count from `spc_runOpcode()`
- Makes it hard to validate cycle accuracy per instruction
**Our improvement:** Return exact cycle count from `Step()`:
```cpp
int Spc700::Step() {
uint8_t opcode = ReadOpcode();
int cycles = CalculatePreciseCycles(opcode);
ExecuteInstructionAtomic(opcode);
return cycles; // EXPLICIT return
}
```
**2. Implicit Cycle Counting**
- Cycles accumulated implicitly through callbacks
- Hard to debug when cycles are wrong
- No way to verify cycle accuracy per instruction
**Our improvement:** Explicit cycle budget model in `Apu::RunCycles()`:
```cpp
while (cycles_ < target_apu_cycles) {
int spc_cycles = spc700_.Step(); // Explicit cycle count
for (int i = 0; i < spc_cycles; ++i) {
Cycle(); // Explicit cycle advancement
}
}
```
**3. No Fixed-Point Ratio**
- LakeSnes also uses floating-point (implicitly in SNES main loop)
- Subject to same precision drift issues
**Our improvement:** Integer numerator/denominator for perfect precision.
### What We're Adopting from LakeSnes
**Atomic instruction execution** - No `bstep` mechanism
**Simple addressing mode functions** - Return address, advance cycles via callbacks
**Cycle advancement per memory access** - Every read/write/idle advances cycles
### What We're Improving Over LakeSnes
**Explicit cycle counting** - `Step()` returns exact cycles consumed
**Cycle budget model** - Clear loop with explicit cycle advancement
**Fixed-point ratio** - Integer arithmetic for perfect precision
**Testability** - Easy to verify cycle counts per instruction
---
## Solution Design
### Phase 1: Atomic Instruction Execution
**Goal:** Eliminate `bstep` mechanism entirely.
**New Design:**
```cpp
// New function signature
int Spc700::Step() {
if (reset_wanted_) { /* handle reset */ return 8; }
if (stopped_) { /* handle stop */ return 2; }
// Fetch opcode
uint8_t opcode = ReadOpcode();
// Calculate EXACT cycle cost upfront
int cycles = CalculatePreciseCycles(opcode);
// Execute instruction COMPLETELY
ExecuteInstructionAtomic(opcode);
return cycles; // Return exact cycles consumed
}
```
**Benefits:**
- One call = one complete instruction
- Cycles calculated before execution
- No state leakage between calls
- Easier debugging
### Phase 2: Precise Cycle Calculation
**New function:**
```cpp
int Spc700::CalculatePreciseCycles(uint8_t opcode) {
int base_cycles = spc700_cycles[opcode];
// Account for addressing mode penalties
switch (opcode) {
case 0x10: case 0x30: /* ... branches ... */
// Branches: +2 cycles if taken (handled in execution)
break;
case 0x15: case 0x16: /* ... abs+X, abs+Y ... */
// Check if page boundary crossed (+1 cycle)
if (will_cross_page_boundary(opcode)) {
base_cycles += 1;
}
break;
// ... more addressing mode checks ...
}
return base_cycles;
}
```
### Phase 3: Refactor `Apu::RunCycles` to Cycle Budget Model
**New implementation:**
```cpp
void Apu::RunCycles(uint64_t master_cycles) {
// 1. Calculate target using FIXED-POINT ratio (Phase 4)
uint64_t master_delta = master_cycles - g_last_master_cycles;
g_last_master_cycles = master_cycles;
// 2. Fixed-point conversion (avoiding floating point)
uint64_t target_apu_cycles = cycles_ + (master_delta * kApuCyclesNumerator) / kApuCyclesDenominator;
// 3. Run until budget exhausted
while (cycles_ < target_apu_cycles) {
// 4. Execute ONE instruction atomically
int spc_cycles_consumed = spc700_.Step();
// 5. Advance DSP/timers for each cycle
for (int i = 0; i < spc_cycles_consumed; ++i) {
Cycle(); // Ticks DSP, timers, increments cycles_
}
}
}
```
### Phase 4: Fixed-Point Cycle Ratio
**Replace floating-point with integer ratio:**
```cpp
// Old (apu.cc:17)
static const double apuCyclesPerMaster = (32040 * 32) / (1364 * 262 * 60.0);
// New
static constexpr uint64_t kApuCyclesNumerator = 32040 * 32; // 1,025,280
static constexpr uint64_t kApuCyclesDenominator = 1364 * 262 * 60; // 21,437,280
```
**Conversion:**
```cpp
apu_cycles = (master_cycles * kApuCyclesNumerator) / kApuCyclesDenominator;
```
**Benefits:**
- Perfect precision (no floating-point drift)
- Integer arithmetic is faster
- Deterministic across platforms

# E2 - Development Guide
This guide summarizes the architecture and implementation standards used across the editor codebase.
## Editor Status (October 2025)
| Editor | State | Notes |
|-------------------|--------------|-------|
| Overworld | Stable | Full feature set; continue regression testing after palette fixes. |
| Message | Stable | Re-test rendering after recent palette work. |
| Emulator | Stable | UI and core subsystems aligned with production builds. |
| Palette | Stable | Serves as the source of truth for palette helpers. |
| Assembly | Stable | No outstanding refactors. |
| Dungeon | Experimental | Requires thorough manual coverage before release. |
| Graphics | Experimental | Large rendering changes in flight; validate texture pipeline. |
| Sprite | Experimental | UI patterns still migrating to the new card system. |
### Screen Editor Notes
- **Title screen**: Vanilla ROM tilemap parsing remains broken. Implement a DMA
parser and confirm the welcome screen renders before enabling painting.
- **Overworld map**: Mode 7 tiling, palette switching, and custom map import/export are in place. The next milestone is faster tile painting.
- **Dungeon map**: Rendering is wired up; tile painting and ROM write-back are still pending.
## 1. Core Architectural Patterns
These patterns, established during the Overworld Editor refactoring, should be applied to all new and existing editor components.
### Pattern 1: Modular Systems
**Principle**: Decompose large, monolithic editor classes into smaller, single-responsibility modules.
- **Rendering**: All drawing logic should be extracted into dedicated `*Renderer` classes (e.g., `OverworldEntityRenderer`). The main editor class should delegate drawing calls, not implement them.
- **UI Panels**: Complex UI panels should be managed by their own classes (e.g., `MapPropertiesSystem`), which then communicate with the parent editor via callbacks.
- **Interaction**: Canvas interaction logic (mouse handling, editing modes) should be separated from the main editor class to simplify state management.
**Benefit**: Smaller, focused modules are easier to test, debug, and maintain. The main editor class becomes a coordinator, which is a much cleaner architecture.
### Pattern 2: Callback-Based Communication
**Principle**: Use `std::function` callbacks for child-to-parent communication to avoid circular dependencies.
- **Implementation**: A parent editor provides its child components with callbacks (typically via a `SetCallbacks` method) during initialization. The child component invokes these callbacks to notify the parent of events or to request actions (like a refresh).
- **Example**: `MapPropertiesSystem` receives a `RefreshCallback` from `OverworldEditor`. When a property is changed in the UI, it calls the function, allowing the `OverworldEditor` to execute the refresh logic without the `MapPropertiesSystem` needing to know anything about the editor itself.
### Pattern 3: Centralized Progressive Loading via `gfx::Arena`
**Principle**: All expensive asset loading operations must be performed asynchronously to prevent UI freezes. The `gfx::Arena` singleton provides a centralized, priority-based system for this.
- **How it Works**:
1. **Queue**: Instead of loading a texture directly, queue it with the arena: `gfx::Arena::Get().QueueDeferredTexture(bitmap, priority);`
2. **Prioritize**: Assign a numerical priority. Lower numbers are higher priority. Use a high priority for assets the user is currently viewing and a low priority for assets that can be loaded in the background.
3. **Process**: In the main `Update()` loop of an editor, process a small batch of textures each frame: `auto batch = gfx::Arena::Get().GetNextDeferredTextureBatch(4, 2);` (e.g., 4 high-priority, 2 low-priority).
- **Benefit**: This provides a globally consistent, non-blocking loading mechanism that is available to all editors and ensures the UI remains responsive.
## 2. UI & Theming System
To ensure a consistent and polished look and feel, all new UI components must adhere to the established theme and helper function system.
### 2.1. The Theme System (`AgentUITheme`)
- **Principle**: **Never use hardcoded colors (`ImVec4`)**. All UI colors must be derived from the central theme.
- **Implementation**: The `AgentUITheme` system (`src/app/editor/agent/agent_ui_theme.h`) provides a struct of semantic color names (e.g., `panel_bg_color`, `status_success`, `provider_ollama`). These colors are automatically derived from the application's current `ThemeManager`.
- **Usage**: Fetch the theme at the beginning of a draw call and use the semantic colors:
```cpp
const auto& theme = AgentUI::GetTheme();
ImGui::PushStyleColor(ImGuiCol_ChildBg, theme.panel_bg_color);
```
### 2.2. Reusable UI Helper Functions
- **Principle**: Encapsulate common UI patterns into helper functions to reduce boilerplate and ensure consistency.
- **Available Helpers** (in `AgentUI` and `gui` namespaces):
- **Panels**: `AgentUI::PushPanelStyle()` / `PopPanelStyle()`
- **Headers**: `AgentUI::RenderSectionHeader(icon, label, color)`
- **Indicators**: `AgentUI::RenderStatusIndicator()` (status dot), `AgentUI::StatusBadge()` (colored text badge).
- **Buttons**: `AgentUI::StyledButton()`, `AgentUI::IconButton()`.
- **Layout**: `AgentUI::VerticalSpacing()`, `AgentUI::HorizontalSpacing()`.
- **Benefit**: Creates a consistent visual language and makes the UI code far more readable and maintainable.
### 2.3. Toolbar Implementation (`CompactToolbar`)
- **Stretching**: To prevent ImGui from stretching the last item in a toolbar, do not use `ImGui::BeginGroup()`. Instead, manage layout with `ImGui::SameLine()` and end the toolbar with `ImGui::NewLine()`.
- **Separators**: Use `ImGui::SeparatorEx(ImGuiSeparatorFlags_Vertical)` for vertical separators that do not affect item layout.
- **Property Inputs**: Use the `toolbar.AddProperty()` method for consistent spacing and sizing of input fields within the toolbar.
## 3. Key System Implementations & Gotchas
### 3.1. Graphics Refresh Logic
- **Immediate vs. Deferred**: When a visual property changes, the texture must be updated on the GPU immediately. Use `Renderer::Get().RenderBitmap()` for an immediate, blocking update. `UpdateBitmap()` is deferred and should not be used for changes the user expects to see instantly.
- **Call Order is Critical**: When a property affecting graphics is changed, the correct sequence of operations is crucial:
1. Update the property in the data model.
2. Call the relevant `Load*()` method (e.g., `map.LoadAreaGraphics()`) to load the new data from the ROM into memory.
3. Force a redraw/re-render of the bitmap.
### 3.2. Multi-Area Map Configuration
- **Use the Helper**: When changing a map's area size (e.g., from `Small` to `Large`), you **must** use the `zelda3::Overworld::ConfigureMultiAreaMap()` method. Do not set the `area_size` property directly.
- **Why**: This method correctly handles the complex logic of assigning parent IDs to all sibling maps and updating the necessary ROM data for persistence. Failure to use it will result in inconsistent state and refresh bugs.
### 3.3. Version-Specific Feature Gating
- **Principle**: The UI must adapt to the features supported by the loaded ROM. Do not show UI for features that are not available.
- **Implementation**: Check the ROM's `asm_version` byte before rendering a UI component. If the feature is not supported, display a helpful message (e.g., "This feature requires ZSCustomOverworld v3+") instead of the UI.
### 3.4. Entity Visibility for Visual Testing
- **Standard**: All overworld entity markers (entrances, exits, items, sprites) should be rendered with a high-contrast color and an alpha of `0.85f` to ensure they are clearly visible against any background.
- **Entrances**: Bright yellow-gold
- **Exits**: Cyan-white
- **Items**: Bright red
- **Sprites**: Bright magenta
## 4. Clang Tooling Configuration
The repository ships curated `.clangd` and `.clang-tidy` files that mirror our
Google-style C++23 guidelines while accommodating ROM hacking patterns.
- `.clangd` consumes `build/compile_commands.json`, enumerates `src/`, `incl/`,
`third_party/`, generated directories, and sets feature flags such as
`YAZE_WITH_GRPC`, `YAZE_WITH_JSON`, and `Z3ED_AI` so IntelliSense matches the
active preset.
- `.clang-tidy` enables the `clang-analyzer`, `performance`, `bugprone`,
`readability`, `modernize`, `google`, and `abseil` suites, but relaxes common
ROM hacking pain points (magic numbers, explicit integer sizing, C arrays,
carefully scoped narrowing conversions).
- The `gfx::SnesColor` utilities intentionally return ImVec4 values in 0‑255
space; rely on the helper converters instead of manual scaling to avoid
precision loss.
- Regenerate the compilation database whenever you reconfigure: `cmake --preset
mac-dbg` (or the platform equivalent) and ensure the file lives at
`build/compile_commands.json`.
- Spot-check tooling with `clang-tidy path/to/file.cc -p build --quiet` or a
batch run via presets before sending larger patches.
## 5. Debugging and Testing
### 5.1. Quick Debugging with Startup Flags
To accelerate your debugging workflow, use command-line flags to jump directly to specific editors and open relevant UI cards:
```bash
# Quick dungeon room testing
./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0"
# Compare multiple rooms
./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0,Room 1,Room 105"
# Full dungeon workspace
./yaze --rom_file=zelda3.sfc --editor=Dungeon \
--cards="Rooms List,Room Matrix,Object Editor,Palette Editor"
# Enable debug logging
./yaze --debug --log_file=debug.log --rom_file=zelda3.sfc --editor=Dungeon
```
**Available Editors**: Assembly, Dungeon, Graphics, Music, Overworld, Palette, Screen, Sprite, Message, Hex, Agent, Settings
**Dungeon Editor Cards**: Rooms List, Room Matrix, Entrances List, Room Graphics, Object Editor, Palette Editor, Room N (where N is room ID 0-319)
See [debugging-startup-flags.md](debugging-startup-flags.md) for complete documentation.
### 5.2. Testing Strategies
For a comprehensive overview of debugging tools and testing strategies, including how to use the logging framework, command-line test runners, and the GUI automation harness for AI agents, please refer to the [Debugging and Testing Guide](E5-debugging-guide.md).
## 5. Command-Line Flag Standardization
**Decision**: All binaries in the yaze project (`yaze`, `z3ed`, `yaze_test`, etc.) will standardize on the **Abseil Flags** library for command-line argument parsing.
### Rationale
- **Consistency**: Provides a single, consistent flag system and user experience across all tools.
- **Industry Standard**: Abseil is a battle-tested and well-documented library used extensively by Google.
- **Features**: It provides robust features out-of-the-box, including automatic `--help` generation, type safety, validation, and `--flagfile` support.
- **Reduced Maintenance**: Eliminates the need to maintain multiple custom flag parsers, reducing the project's technical debt.
- **Existing Dependency**: Abseil is already included as a dependency via gRPC, so this adds no new third-party code.
### Migration Plan
The project will migrate away from the legacy `yaze::util::Flag` system and manual parsing in phases. All new flags should be implemented using `ABSL_FLAG`.
- **Phase 1 (Complete)**: `z3ed` and `yaze_emu_test` already use Abseil flags.
- **Phase 2 (In Progress)**: The main `yaze` application will be migrated from the custom `util::Flag` system to Abseil flags.
- **Phase 3 (Future)**: The `yaze_test` runner's manual argument parsing will be replaced with Abseil flags.
- **Phase 4 (Cleanup)**: The legacy `util::flag` source files will be removed from the project.
Developers should refer to the Abseil Flags Guide for documentation on defining, declaring, and accessing flags.
---
When working with bitmaps and textures, understand that two memory locations must stay synchronized:
1. **`data_` vector**: C++ std::vector<uint8_t> holding pixel data
2. **`surface_->pixels`**: SDL surface's raw pixel buffer (used for texture creation)
**Critical Rules**:
- Use `set_data()` for bulk data replacement (syncs both vector and surface)
- Use `WriteToPixel()` for single-pixel modifications
- Never assign directly to `mutable_data()` for replacements (only updates vector, not surface)
- Always call `ProcessTextureQueue()` every frame to process pending texture operations
**Example**:
```cpp
// WRONG - only updates vector
bitmap.mutable_data() = new_data;
// CORRECT - updates both vector and SDL surface
bitmap.set_data(new_data);
```
### 3.6. Graphics Sheet Management
Graphics sheets (223 total) are managed centrally by `gfx::Arena`. When modifying a sheet:
1. Modify the sheet: `auto& sheet = Arena::Get().mutable_gfx_sheet(index);`
2. Notify Arena: `Arena::Get().NotifySheetModified(index);`
3. Changes automatically propagate to all editors
Default palettes are applied during ROM loading based on sheet index:
- Sheets 0-112: Dungeon main palettes
- Sheets 113-127: Sprite palettes
- Sheets 128-222: HUD/menu palettes
### Naming Conventions
- Load: Reading data from ROM into memory
- Render: Processing graphics data into bitmaps/textures (CPU pixel operations)
- Draw: Displaying textures/shapes on canvas via ImGui (GPU rendering)
- Update: UI state changes, property updates, input handling

# Dungeon Editor Guide
## Overview
The Yaze Dungeon Editor is a comprehensive tool for editing Zelda 3: A Link to the Past dungeon rooms, objects, sprites, items, entrances, doors, and chests. It provides an integrated editing experience with real-time rendering, coordinate system management, and advanced features for dungeon modification.
## Architecture
### Core Components
#### 1. DungeonEditorSystem

## Coordinate System
### Room Coordinates vs Canvas Coordinates
The dungeon editor uses a two-tier coordinate system:
1. **Room Coordinates**: 16x16 tile units (as used in the ROM)
2. **Canvas Coordinates**: Pixel coordinates for rendering
#### Conversion Functions
```cpp
// Convert room coordinates to canvas coordinates
std::pair<int, int> RoomToCanvasCoordinates(int room_x, int room_y) const {
return {room_x * 16, room_y * 16};
}
// Convert canvas coordinates to room coordinates
std::pair<int, int> CanvasToRoomCoordinates(int canvas_x, int canvas_y) const {
return {canvas_x / 16, canvas_y / 16};
}
// Check if coordinates are within canvas bounds
bool IsWithinCanvasBounds(int canvas_x, int canvas_y, int margin = 32) const;
```
### Coordinate System Features
- **Automatic Bounds Checking**: Objects outside visible canvas area are culled
- **Scrolling Support**: Canvas handles scrolling internally with proper coordinate transformation
- **Grid Alignment**: 16x16 pixel grid for precise object placement
- **Margin Support**: Configurable margins for partial object visibility
## Object Rendering System
### Object Types
The system supports three main object subtypes based on ROM structure:
1. **Subtype 1** (0x00-0xFF): Standard room objects (walls, floors, decorations)
2. **Subtype 2** (0x100-0x1FF): Interactive objects (doors, switches, chests)
3. **Subtype 3** (0x200+): Special objects (stairs, warps, bosses)
### Rendering Pipeline
1. **Object Loading**: Objects are loaded from ROM data using `LoadObjects()`
2. **Tile Parsing**: Object tiles are parsed using `ObjectParser`
3. **Graphics Caching**: Frequently used graphics are cached for performance
4. **Palette Application**: SNES palettes are applied to object graphics
5. **Canvas Rendering**: Objects are rendered to canvas with proper coordinate transformation
### Performance Optimizations
- **Graphics Cache**: Reduces redundant graphics sheet loading
- **Memory Pool**: Efficient memory allocation for rendering
- **Batch Rendering**: Multiple objects rendered in single pass
- **Bounds Culling**: Objects outside visible area are skipped
- **Cache Invalidation**: Smart cache management based on palette changes
## User Interface

- Big chest support
- Opened status tracking
7. **Properties Editor**
- Room metadata management
- Dungeon settings
- Music and ambient sound configuration
- Boss room and save room flags
### Object Preview System
- **Real-time Preview**: Objects are previewed in the canvas as they're selected
- **Centered Display**: Preview objects are centered in the canvas for optimal viewing
- **Palette Support**: Previews use current palette settings
- **Information Display**: Object properties are shown in preview window
## Integration with ZScream
The dungeon editor is designed to be compatible with ZScream C# patterns:
### Room Loading

## Usage Examples
### Basic Object Editing
```cpp
// Load a room
auto room_result = dungeon_editor_system_->GetRoom(0x0000);
// Add an object
auto status = object_editor_->InsertObject(5, 5, 0x10, 0x12, 0);
// Parameters: x, y, object_type, size, layer
// Render objects
auto result = object_renderer_->RenderObjects(objects, palette);
```
### Coordinate Conversion
```cpp
// Convert room coordinates to canvas coordinates
auto [canvas_x, canvas_y] = RoomToCanvasCoordinates(room_x, room_y);
// Check if coordinates are within bounds
if (IsWithinCanvasBounds(canvas_x, canvas_y)) {
// Render object at this position
}
```
### Object Preview
```cpp
// Create preview object
auto preview_object = zelda3::RoomObject(id, 8, 8, 0x12, 0);
preview_object.set_rom(rom_);
preview_object.EnsureTilesLoaded();
// Render preview
auto result = object_renderer_->RenderObject(preview_object, palette);
```
## Configuration Options

# API Reference
This document provides a reference for the yaze C and C++ APIs, intended for developers creating extensions or contributing to the core application.
## C API (`incl/yaze.h`)
The C API provides a stable, language-agnostic interface for interacting with yaze's core functionalities.
### Core Library Functions
```c
/**
* @brief Initializes the yaze library. Must be called before any other API function.
* @return YAZE_OK on success, or an error code on failure.
*/
yaze_status yaze_library_init(void);
/**
* @brief Shuts down the yaze library and releases all resources.
*/
void yaze_library_shutdown(void);
/**
* @brief Gets the current version of the yaze library as a string.
* @return A constant string representing the version (e.g., "0.3.2").
*/
const char* yaze_get_version_string(void);
```
### ROM Operations
```c
/**
* @brief Loads a Zelda 3 ROM from a file.
* @param filename The path to the ROM file.
* @return A pointer to a zelda3_rom object, or NULL on failure.
*/
zelda3_rom* yaze_load_rom(const char* filename);
/**
* @brief Unloads a ROM and frees associated memory.
* @param rom A pointer to the zelda3_rom object to unload.
*/
void yaze_unload_rom(zelda3_rom* rom);
/**
* @brief Saves a ROM to a file.
* @param rom A pointer to the ROM to save.
* @param filename The path to save the file to.
* @return YAZE_OK on success.
*/
yaze_status yaze_save_rom(zelda3_rom* rom, const char* filename);
```
## C++ API
The C++ API offers a more powerful, object-oriented interface. The primary entry point for many operations is the `yaze::core::AsarWrapper` class.
### AsarWrapper (`src/core/asar_wrapper.h`)
This class provides a complete, cross-platform interface for applying assembly patches, extracting symbols, and validating assembly code using the Asar library.
#### CLI Examples (`z3ed`)
While the `AsarWrapper` can be used programmatically, the `z3ed` CLI is the most common way to interact with it.
```bash
# Apply an assembly patch to a ROM file.
z3ed asar my_patch.asm --rom=zelda3.sfc
# For more complex operations, use the AI agent.
z3ed agent chat --rom zelda3.sfc
```
> **Prompt:** "Apply the patch `mosaic_change.asm` to my ROM."
#### C++ API Example
```cpp
#include "core/asar_wrapper.h"
#include <vector>
#include <string>
// Assume rom_data is a std::vector<uint8_t> holding the ROM content.
yaze::core::AsarWrapper wrapper;
wrapper.Initialize();
// Apply a patch to the ROM data in memory.
auto result = wrapper.ApplyPatch("patch.asm", rom_data);
if (result.ok() && result->success) {
// On success, print the symbols generated by the patch.
for (const auto& symbol : result->symbols) {
std::cout << symbol.name << " @ $" << std::hex << symbol.address << std::endl;
}
}
```
#### Class Definition
```cpp
namespace yaze::core {
class AsarWrapper {
public:
/** @brief Initializes the Asar library. */
absl::Status Initialize();
/** @brief Shuts down the Asar library. */
void Shutdown();
/**
* @brief Applies an assembly patch to ROM data.
* @param patch_path Path to the main .asm file.
* @param rom_data A vector of bytes representing the ROM data.
* @param include_paths Optional paths for Asar to search for included files.
* @return A StatusOr containing the patch result, including success status and symbols.
*/
absl::StatusOr<AsarPatchResult> ApplyPatch(
const std::string& patch_path,
std::vector<uint8_t>& rom_data,
const std::vector<std::string>& include_paths = {});
/**
* @brief Extracts symbols from an assembly file without patching.
* @param asm_path Path to the .asm file.
* @return A StatusOr containing a vector of extracted symbols.
*/
absl::StatusOr<std::vector<AsarSymbol>> ExtractSymbols(
const std::string& asm_path,
const std::vector<std::string>& include_paths = {});
/**
* @brief Validates the syntax of an assembly file.
* @param asm_path Path to the .asm file.
* @return An OK status if syntax is valid, or an error status if not.
*/
absl::Status ValidateAssembly(const std::string& asm_path);
};
} // namespace yaze::core
```
## Data Structures
### `snes_color`
Represents a 15-bit SNES color, composed of 5 bits for each red, green, and blue component.
```c
typedef struct snes_color {
uint16_t raw; //!< Raw 15-bit BGR color value (0bbbbbgggggrrrrr).
uint8_t red; //!< Red component (0-31).
uint8_t green; //!< Green component (0-31).
uint8_t blue; //!< Blue component (0-31).
} snes_color;
```
### `zelda3_message`
Represents an in-game text message.
```c
typedef struct zelda3_message {
uint16_t id; //!< The message ID (0-65535).
uint32_t rom_address; //!< The address of the message data in the ROM.
uint16_t length; //!< The length of the raw message data in bytes.
uint8_t* raw_data; //!< A pointer to the raw, compressed message data.
char* parsed_text; //!< The decoded, human-readable UTF-8 text.
bool is_compressed; //!< Flag indicating if the message data is compressed.
}
zelda3_message;
```
## Error Handling
The C API uses an enum `yaze_status` for error handling, while the C++ API uses `absl::Status` and `absl::StatusOr`.
### C API Error Pattern
```c
yaze_status status = yaze_library_init();
if (status != YAZE_OK) {
fprintf(stderr, "Failed to initialize YAZE: %s\n", yaze_status_to_string(status));
return 1;
}
// ... operations ...
yaze_library_shutdown();
```

# Dungeon Editor Design Plan
## Overview
This document provides a comprehensive guide for future developers working on the Zelda 3 Dungeon Editor system. The dungeon editor has been refactored into a modular, component-based architecture that separates concerns and improves maintainability.
## Architecture Overview
### Core Components
The dungeon editor system consists of several key components:
1. **DungeonEditor** - Main orchestrator class that manages the overall editor state
2. **DungeonRoomSelector** - Handles room and entrance selection UI
3. **DungeonCanvasViewer** - Manages the main canvas rendering and room display
4. **DungeonObjectSelector** - Provides object selection, editing panels, and tile graphics
5. **ObjectRenderer** - Core rendering engine for dungeon objects
6. **DungeonEditorSystem** - High-level system for managing dungeon editing operations
### File Structure
```
src/app/editor/dungeon/
├── dungeon_editor.h/cc # Main editor orchestrator
├── dungeon_room_selector.h/cc # Room/entrance selection component
├── dungeon_canvas_viewer.h/cc # Canvas rendering component
├── dungeon_object_selector.h/cc # Object editing component
└── dungeon_editor_system.h/cc # Core editing system
src/app/zelda3/dungeon/
├── object_renderer.h/cc # Object rendering engine
├── dungeon_object_editor.h/cc # Object editing logic
├── room.h/cc # Room data structures
├── room_object.h/cc # Object data structures
└── room_entrance.h/cc # Entrance data structures
```
## Component Responsibilities
### DungeonEditor (Main Orchestrator)
**Responsibilities:**
- Manages overall editor state and ROM data
- Coordinates between UI components
- Handles data initialization and propagation
- Implements the 3-column layout (Room Selector | Canvas | Object Selector)
**Key Methods:**
- `UpdateDungeonRoomView()` - Main UI update loop
- `Load()` - Initialize editor with ROM data
- `set_rom()` - Update ROM reference across components
### DungeonRoomSelector
**Responsibilities:**
- Room selection and navigation
- Entrance selection and editing
- Active room management
- Room list display with names
**Key Methods:**
- `Draw()` - Main rendering method
- `DrawRoomSelector()` - Room list and selection
- `DrawEntranceSelector()` - Entrance editing interface
- `set_rom()`, `set_rooms()`, `set_entrances()` - Data access methods
### DungeonCanvasViewer
**Responsibilities:**
- Main canvas rendering and display
- Room graphics loading and management
- Object rendering with proper coordinates
- Background layer management
- Coordinate conversion (room ↔ canvas)
**Key Methods:**
- `Draw(int room_id)` - Main canvas rendering
- `LoadAndRenderRoomGraphics()` - Graphics loading
- `RenderObjectInCanvas()` - Object rendering
- `RoomToCanvasCoordinates()` - Coordinate conversion
- `RenderRoomBackgroundLayers()` - Background rendering
### DungeonObjectSelector
**Responsibilities:**
- Object selection and preview
- Tile graphics display
- Compact editing panels for all editor modes
- Object renderer integration
**Key Methods:**
- `Draw()` - Main rendering with tabbed interface
- `DrawRoomGraphics()` - Tile graphics display
- `DrawIntegratedEditingPanels()` - Editing interface
- `DrawCompactObjectEditor()` - Object editing controls
- `DrawCompactSpriteEditor()` - Sprite editing controls
- Similar methods for Items, Entrances, Doors, Chests, Properties
## Data Flow
### Initialization Flow
1. **ROM Loading**: `DungeonEditor::Load()` is called with ROM data
2. **Component Setup**: ROM and data pointers are propagated to all components
3. **Graphics Initialization**: Room graphics are loaded and cached
4. **UI State Setup**: Active rooms, palettes, and editor modes are initialized
### Runtime Data Flow
1. **User Interaction**: User selects rooms, objects, or editing modes
2. **State Updates**: Components update their internal state
3. **Data Propagation**: Changes are communicated between components
4. **Rendering**: All components re-render with updated data
### Key Data Structures
```cpp
// Main editor state
std::array<zelda3::Room, 0x128> rooms_;
std::array<zelda3::RoomEntrance, 0x8C> entrances_;
ImVector<int> active_rooms_;
gfx::PaletteGroup current_palette_group_;
// Component instances
DungeonRoomSelector room_selector_;
DungeonCanvasViewer canvas_viewer_;
DungeonObjectSelector object_selector_;
```
## Integration Patterns
### Component Communication
Components communicate through:
1. **Direct method calls** - Parent calls child methods
2. **Data sharing** - Shared pointers to common data structures
3. **Event propagation** - State changes trigger updates
### ROM Data Management
```cpp
// ROM propagation pattern
void DungeonEditor::set_rom(Rom* rom) {
rom_ = rom;
room_selector_.set_rom(rom);
canvas_viewer_.SetRom(rom);
object_selector_.SetRom(rom);
}
```
### State Synchronization
Components maintain their own state but receive updates from the main editor:
- Room selection state is managed by `DungeonRoomSelector`
- Canvas rendering state is managed by `DungeonCanvasViewer`
- Object editing state is managed by `DungeonObjectSelector`
## UI Layout Architecture
### 3-Column Layout
The main editor uses a 3-column ImGui table layout:
```cpp
if (BeginTable("#DungeonEditTable", 3, kDungeonTableFlags, ImVec2(0, 0))) {
TableSetupColumn("Room/Entrance Selector", ImGuiTableColumnFlags_WidthFixed, 250);
TableSetupColumn("Canvas", ImGuiTableColumnFlags_WidthStretch);
TableSetupColumn("Object Selector/Editor", ImGuiTableColumnFlags_WidthFixed, 300);
// Column 1: Room Selector
TableNextColumn();
room_selector_.Draw();
// Column 2: Canvas
TableNextColumn();
canvas_viewer_.Draw(current_room);
// Column 3: Object Selector
TableNextColumn();
object_selector_.Draw();
}
```
### Component Internal Layout
Each component manages its own internal layout:
- **DungeonRoomSelector**: Tabbed interface (Rooms | Entrances)
- **DungeonCanvasViewer**: Canvas with controls and debug popup
- **DungeonObjectSelector**: Tabbed interface (Graphics | Editor)
## Coordinate System
### Room Coordinates vs Canvas Coordinates
- **Room Coordinates**: 16x16 tile units (0-15 for a standard room)
- **Canvas Coordinates**: Pixel coordinates for rendering
- **Conversion**: `RoomToCanvasCoordinates(x, y) = (x * 16, y * 16)`
### Bounds Checking
All rendering operations include bounds checking:
```cpp
bool IsWithinCanvasBounds(int canvas_x, int canvas_y, int margin = 32) const;
```
## Error Handling & Validation
### ROM Validation
All components validate ROM state before operations:
```cpp
if (!rom_ || !rom_->is_loaded()) {
ImGui::Text("ROM not loaded");
return;
}
```
### Bounds Validation
Graphics operations include bounds checking:
```cpp
if (room_id < 0 || room_id >= rooms_->size()) {
return; // Skip invalid operations
}
```
## Performance Considerations
### Caching Strategy
- **Object Render Cache**: Cached rendered bitmaps to avoid re-rendering
- **Graphics Cache**: Cached graphics sheets for frequently accessed data
- **Memory Pool**: Efficient memory allocation for temporary objects
### Rendering Optimization
- **Viewport Culling**: Objects outside visible area are not rendered
- **Lazy Loading**: Graphics are loaded only when needed
- **Selective Updates**: Only changed components re-render
## Testing Strategy
### Integration Tests
The system includes comprehensive integration tests:
- `dungeon_object_renderer_integration_test.cc` - Core rendering tests
- `dungeon_editor_system_integration_test.cc` - System integration tests
- `dungeon_object_renderer_mock_test.cc` - Mock ROM testing
### Test Categories
1. **Real ROM Tests**: Tests with actual Zelda 3 ROM data
2. **Mock ROM Tests**: Tests with simulated ROM data
3. **Performance Tests**: Rendering performance benchmarks
4. **Error Handling Tests**: Validation and error recovery
## Future Development Guidelines
### Adding New Features
1. **Identify Component**: Determine which component should handle the feature
2. **Extend Interface**: Add necessary methods to component header
3. **Implement Logic**: Add implementation in component source file
4. **Update Integration**: Modify main editor to use new functionality
5. **Add Tests**: Create tests for new functionality
### Component Extension Patterns
```cpp
// Adding new data access method
void Component::SetNewData(const NewDataType& data) {
new_data_ = data;
}
// Adding new rendering method
void Component::DrawNewFeature() {
// Implementation
}
// Adding to main Draw method
void Component::Draw() {
// Existing code
DrawNewFeature();
}
```
### Data Flow Extension
When adding new data types:
1. Add to main editor state
2. Create setter methods in relevant components
3. Update initialization in `Load()` method
4. Add to `set_rom()` propagation if ROM-dependent
### UI Layout Extension
For new UI elements:
1. Determine placement (new tab, new panel, etc.)
2. Follow existing ImGui patterns
3. Maintain consistent spacing and styling
4. Add to appropriate component's Draw method
## Common Pitfalls & Solutions
### Memory Management
- **Issue**: Dangling pointers to ROM data
- **Solution**: Always validate ROM state before use
### Coordinate System
- **Issue**: Objects rendering at wrong positions
- **Solution**: Use coordinate conversion helper methods
### State Synchronization
- **Issue**: Components showing stale data
- **Solution**: Ensure data propagation in setter methods
### Performance Issues
- **Issue**: Slow rendering with many objects
- **Solution**: Implement viewport culling and caching
## Debugging Tools
### Debug Popup
The canvas viewer includes a comprehensive debug popup with:
- Object statistics and metadata
- Cache information
- Performance metrics
- Object type breakdowns
### Logging
Key operations include logging for debugging:
```cpp
std::cout << "Loading room graphics for room " << room_id << std::endl;
```
## Build Integration
### CMake Configuration
New components are automatically included via:
```cmake
# In CMakeLists.txt
file(GLOB YAZE_SRC_FILES "src/app/editor/dungeon/*.cc")
```
### Dependencies
Key dependencies:
- ImGui for UI rendering
- gfx library for graphics operations
- zelda3 library for ROM data structures
- absl for status handling
## Conclusion
This modular architecture provides a solid foundation for future dungeon editor development. The separation of concerns makes the codebase maintainable, testable, and extensible. Future developers should follow the established patterns and extend components rather than modifying the main orchestrator class.
For questions or clarifications, refer to the existing integration tests and component implementations as examples of proper usage patterns.

# E5 - Debugging and Testing Guide
**Last Updated**: October 9, 2025
**Status**: Active
This document provides a comprehensive guide to debugging and testing the `yaze` application. It covers strategies for developers and provides the necessary information for AI agents to interact with, test, and validate the application.
---
## 1. Standardized Logging for Print Debugging
For all print-based debugging, `yaze` uses a structured logging system defined in `util/log.h`. This is the **only** approved method for logging; direct use of `printf` or `std::cout` should be avoided and replaced with the appropriate `LOG_*` macro.
### Log Levels and Usage
- `LOG_DEBUG(category, "message", ...)`: For verbose, development-only information.
- `LOG_INFO(category, "message", ...)`: For general, informational messages.
- `LOG_WARN(category, "message", ...)`: For potential issues that don't break functionality.
- `LOG_ERROR(category, "message", ...)`: For errors that cause a specific operation to fail.
### Log Categories
Categories allow you to filter logs to focus on a specific subsystem. Common categories include:
- `"Main"`
- `"TestManager"`
- `"EditorManager"`
- `"APU"`, `"CPU"`, `"SNES"` (for the emulator)
### Enabling and Configuring Logs via CLI
You can control logging behavior using command-line flags when launching `yaze` or `yaze_test`.
- **Enable Verbose Debug Logging**:
```bash
./build/bin/yaze --debug
```
- **Log to a File**:
```bash
./build/bin/yaze --log_file=yaze_debug.log
```
- **Filter by Category**:
```bash
# Only show logs from the APU and CPU emulator components
./build/bin/yaze_emu --emu_debug_apu=true --emu_debug_cpu=true
```
**Best Practice**: When debugging a specific component, add detailed `LOG_DEBUG` statements with a unique category. Then, run `yaze` with the appropriate flags to isolate the output.
---
## 2. Command-Line Workflows for Testing
The `yaze` ecosystem provides several executables and flags to streamline testing and debugging.
### Launching the GUI for Specific Tasks
- **Load a ROM on Startup**: To immediately test a specific ROM, use the `--rom_file` flag. This bypasses the welcome screen.
```bash
./build/bin/yaze --rom_file /path/to/your/zelda3.sfc
```
- **Enable the GUI Test Harness**: To allow the `z3ed` CLI to automate the GUI, you must start `yaze` with the gRPC server enabled.
```bash
./build/bin/yaze --rom_file zelda3.sfc --enable_test_harness
```
- **Open a Specific Editor and Cards**: To quickly test a specific editor and its components, use the `--editor` and `--cards` flags. This is especially useful for debugging complex UIs like the Dungeon Editor.
```bash
# Open the Dungeon Editor with the Room Matrix and two specific room cards
./build/bin/yaze --rom_file zelda3.sfc --editor=Dungeon --cards="Room Matrix,Room 0,Room 105"
# Available editors: Assembly, Dungeon, Graphics, Music, Overworld, Palette,
# Screen, Sprite, Message, Hex, Agent, Settings
# Dungeon editor cards: Rooms List, Room Matrix, Entrances List, Room Graphics,
# Object Editor, Palette Editor, Room N (where N is room ID)
```
**Quick Examples**:
```bash
# Fast dungeon room testing
./build/bin/yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0"
# Compare multiple rooms side-by-side
./build/bin/yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0,Room 1,Room 105"
# Full dungeon workspace with all tools
./build/bin/yaze --rom_file=zelda3.sfc --editor=Dungeon \
--cards="Rooms List,Room Matrix,Object Editor,Palette Editor"
# Jump straight to overworld editing
./build/bin/yaze --rom_file=zelda3.sfc --editor=Overworld
```
For a complete reference, see [docs/debugging-startup-flags.md](debugging-startup-flags.md).
### Running Automated C++ Tests
The `yaze_test` executable is used to run the project's suite of unit, integration, and E2E tests.
- **Run All Tests**:
```bash
./build_ai/bin/yaze_test
```
- **Run Specific Categories**:
```bash
# Run only fast, dependency-free unit tests
./build_ai/bin/yaze_test --unit
# Run tests that require a ROM file
./build_ai/bin/yaze_test --rom-dependent --rom-path /path/to/zelda3.sfc
```
- **Run GUI-based E2E Tests**:
```bash
# Run E2E tests and watch the GUI interactions
./build_ai/bin/yaze_test --e2e --show-gui
```
### Inspecting ROMs with `z3ed`
The `z3ed` CLI is a powerful tool for inspecting ROM data without launching the full GUI. This is ideal for quick checks and scripting.
- **Get ROM Information**:
```bash
z3ed rom info --rom zelda3.sfc
```
- **Inspect Dungeon Sprites**:
```bash
z3ed dungeon list-sprites --rom zelda3.sfc --dungeon 2
```
---
## 3. GUI Automation for AI Agents
The primary way for an AI agent to test its changes and interact with `yaze` is through the GUI automation framework. This system consists of the `yaze` gRPC server (Test Harness) and the `z3ed` CLI client.
### Architecture Overview
1. **`yaze` (Server)**: When launched with `--enable_test_harness`, it starts a gRPC server that exposes the UI for automation.
2. **`z3ed` (Client)**: The `z3ed agent test` commands connect to the gRPC server to send commands and receive information.
3. **AI Agent**: The agent generates `z3ed` commands to drive the UI and verify its actions.
### Step-by-Step Workflow for AI
#### Step 1: Launch `yaze` with the Test Harness
The AI must first ensure the `yaze` GUI is running and ready for automation.
```bash
./build/bin/yaze --rom_file zelda3.sfc --enable_test_harness --test_harness_port 50051
```
#### Step 2: Discover UI Elements
Before interacting with the UI, the agent needs to know the stable IDs of the widgets.
```bash
# Discover all widgets in the Dungeon editor window
z3ed agent test discover --window "Dungeon" --grpc localhost:50051
```
This will return a list of widget IDs (e.g., `Dungeon/Canvas/Map`) that can be used in scripts.
**Tip**: You can also launch `yaze` with the `--editor` flag to automatically open a specific editor:
```bash
./build/bin/yaze --rom_file zelda3.sfc --enable_test_harness --editor=Dungeon --cards="Room 0"
```
#### Step 3: Record or Write a Test Script
An agent can either generate a test script from scratch or use a pre-recorded one.
- **Recording a human interaction**:
```bash
z3ed agent test record --suite my_test.jsonl
```
- **A generated script might look like this**:
```json
// my_test.jsonl
{"action": "click", "target": "Dungeon/Toolbar/Open Room"}
{"action": "wait", "duration_ms": 500}
{"action": "type", "target": "Room Selector/Filter", "text": "Room 105"}
{"action": "click", "target": "Room Selector/List/Room 105"}
{"action": "assert_visible", "target": "Room Card 105"}
```
- **Or use startup flags to prepare the environment**:
```bash
# Start yaze with the room already open
./build/bin/yaze --rom_file zelda3.sfc --enable_test_harness \
--editor=Dungeon --cards="Room 105"
# Then your test script just needs to validate the state
{"action": "assert_visible", "target": "Room Card 105"}
{"action": "assert_visible", "target": "Dungeon/Canvas"}
```
#### Step 4: Replay the Test and Verify
The agent executes the script to perform the actions and validate the outcome.
```bash
z3ed agent test replay my_test.jsonl --watch
```
The `--watch` flag streams results back to the CLI in real-time. The agent can parse this output to confirm its actions were successful.
---
## 4. Advanced Debugging Tools
For more complex issues, especially within the emulator, `yaze` provides several advanced debugging windows. These are covered in detail in the [Emulator Development Guide](E4-Emulator-Development-Guide.md).
- **Disassembly Viewer**: A live, interactive view of the 65816 and SPC700 CPU execution.
- **Breakpoint Manager**: Set breakpoints on code execution, memory reads, or memory writes.
- **Memory Viewer**: Inspect WRAM, SRAM, VRAM, and ROM.
- **APU Inspector**: A dedicated debugger for the audio subsystem.
- **Event Viewer**: A timeline of all hardware events (NMI, IRQ, DMA).
These tools are accessible from the **Debug** menu in the main application.

# Dungeon Object System
## Overview
The Dungeon Object System provides a comprehensive framework for editing and managing dungeon rooms, objects, and layouts in The Legend of Zelda: A Link to the Past. This system combines real-time visual editing with precise data manipulation to create a powerful dungeon creation and modification toolkit.
## Architecture
### Core Components
The dungeon system is built around several key components that work together to provide a seamless editing experience:
#### 1. DungeonEditor (`src/app/editor/dungeon/dungeon_editor.h`)
The main interface that orchestrates all dungeon editing functionality. It provides:
- **Windowed Canvas System**: Fixed-size canvas that prevents UI layout disruption
- **Tabbed Room Interface**: Multiple rooms can be open simultaneously for easy comparison and editing
- **Integrated Object Placement**: Direct object placement from selector to canvas
- **Real-time Preview**: Live object preview follows mouse cursor during placement
#### 2. DungeonObjectSelector (`src/app/editor/dungeon/dungeon_object_selector.h`)
Combines object browsing and editing in a unified interface:
- **Object Browser**: Visual grid of all available objects with real-time previews
- **Object Editor**: Integrated editing panels for sprites, items, entrances, doors, and chests
- **Callback System**: Notifies main editor when objects are selected for placement
#### 3. DungeonCanvasViewer (`src/app/editor/dungeon/dungeon_canvas_viewer.h`)
Specialized canvas for rendering dungeon rooms:
- **Background Layer Rendering**: Proper BG1/BG2 layer composition
- **Object Rendering**: Cached object rendering with palette support
- **Coordinate System**: Seamless translation between room and canvas coordinates
#### 4. Room Management System (`src/app/zelda3/dungeon/room.h`)
Core data structures for room representation:
- **Room Objects**: Tile-based objects (walls, floors, decorations)
- **Room Layout**: Structural elements and collision data
- **Sprites**: Enemy and NPC placement
- **Entrances/Exits**: Room connections and transitions
## Object Types and Hierarchies
### Room Objects
Room objects are the fundamental building blocks of dungeon rooms. They follow a hierarchical structure:
#### Type 1 Objects (0x00-0xFF)
Basic structural elements:
- **0x10-0x1F**: Wall objects (various types and orientations)
- **0x20-0x2F**: Floor tiles (stone, wood, carpet, etc.)
- **0x30-0x3F**: Decorative elements (torches, statues, pillars)
- **0x40-0x4F**: Interactive elements (switches, blocks)
#### Type 2 Objects (0x100-0x1FF)
Complex multi-tile objects:
- **0x100-0x10F**: Large wall sections
- **0x110-0x11F**: Complex floor patterns
- **0x120-0x12F**: Multi-tile decorations
#### Type 3 Objects (0x200+)
Special dungeon-specific objects:
- **0x200-0x20F**: Boss room elements
- **0x210-0x21F**: Puzzle-specific objects
- **0xF9-0xFA**: Chests (small and large)
### Object Properties
Each object has several key properties:
```cpp
class RoomObject {
int id_; // Object type identifier
int x_, y_; // Position in room (16x16 tile units)
int size_; // Size modifier (affects rendering)
LayerType layer_; // Rendering layer (0=BG, 1=MID, 2=FG)
// ... additional properties
};
```
## How Object Placement Works
### Selection Process
1. **Object Browser**: User selects an object from the visual grid
2. **Preview Generation**: Object is rendered with current room palette
3. **Callback Trigger**: Selection notifies main editor via callback
4. **Preview Update**: Main editor receives object and enables placement mode
### Placement Process
1. **Mouse Tracking**: Preview object follows mouse cursor on canvas
2. **Coordinate Translation**: Mouse position converted to room coordinates
3. **Visual Feedback**: Semi-transparent preview shows placement position
4. **Click Placement**: Left-click places object at current position
5. **Room Update**: Object added to room data and cache cleared for redraw
### Code Flow
```cpp
// Object selection in DungeonObjectSelector
if (ImGui::Selectable("", is_selected)) {
preview_object_ = selected_object;
object_loaded_ = true;
// Notify main editor
if (object_selected_callback_) {
object_selected_callback_(preview_object_);
}
}
// Object placement in DungeonEditor
void PlaceObjectAtPosition(int room_x, int room_y) {
auto new_object = preview_object_;
new_object.x_ = room_x;
new_object.y_ = room_y;
new_object.set_rom(rom_);
new_object.EnsureTilesLoaded();
room.AddTileObject(new_object);
object_render_cache_.clear(); // Force redraw
}
```
## Rendering Pipeline
### Object Rendering
The system uses a sophisticated rendering pipeline:
1. **Tile Loading**: Object tiles loaded from ROM based on object ID
2. **Palette Application**: Room-specific palette applied to object
3. **Bitmap Generation**: Object rendered to bitmap with proper composition
4. **Caching**: Rendered objects cached for performance
5. **Canvas Drawing**: Bitmap drawn to canvas at correct position
### Performance Optimizations
- **Render Caching**: Objects cached based on ID, position, size, and palette hash
- **Bounds Checking**: Only objects within canvas bounds are rendered
- **Lazy Loading**: Graphics and objects loaded on-demand
- **Palette Hashing**: Efficient cache invalidation when palettes change
## User Interface Components
### Three-Column Layout
The dungeon editor uses a carefully designed three-column layout:
#### Column 1: Room Control Panel (280px fixed)
- **Room Selector**: Browse and select rooms
- **Debug Controls**: Room properties in table format
- **Object Statistics**: Live object counts and cache status
#### Column 2: Windowed Canvas (800px fixed)
- **Tabbed Interface**: Multiple rooms open simultaneously
- **Fixed Dimensions**: Prevents UI layout disruption
- **Real-time Preview**: Object placement preview follows cursor
- **Layer Visualization**: Proper background/foreground rendering
#### Column 3: Object Selector/Editor (stretch)
- **Object Browser Tab**: Visual grid of available objects
- **Object Editor Tab**: Integrated editing for sprites, items, etc.
- **Placement Tools**: Object property editing and placement controls
### Debug and Control Features
#### Room Properties Table
Real-time editing of room attributes:
```
Property | Value
------------|--------
Room ID | 0x001 (1)
Layout | [Hex Input]
Blockset | [Hex Input]
Spriteset | [Hex Input]
Palette | [Hex Input]
Floor 1 | [Hex Input]
Floor 2 | [Hex Input]
Message ID | [Hex Input]
```
#### Object Statistics
Live feedback on room contents:
- Total objects count
- Layout objects count
- Sprites count
- Chests count
- Cache status and controls
## Integration with ROM Data
### Data Sources
The system integrates with multiple ROM data sources:
#### Room Headers (`0x1F8000`)
- Room layout index
- Blockset and spriteset references
- Palette assignments
- Floor type definitions
#### Object Data
- Object definitions and tile mappings
- Size and layer information
- Interaction properties
#### Graphics Data
- Tile graphics (4bpp SNES format)
- Palette data (15-color palettes)
- Blockset compositions
### Assembly Integration
The system references the US disassembly (`assets/asm/usdasm/`) for:
- Room data structure validation
- Object type definitions
- Memory layout verification
- Data pointer validation
## Comparison with ZScream
### Architectural Differences
YAZE's approach differs from ZScream in several key ways:
#### Component-Based Architecture
- **YAZE**: Modular components with clear separation of concerns
- **ZScream**: More monolithic approach with integrated functionality
#### Real-time Rendering
- **YAZE**: Live object preview with mouse tracking
- **ZScream**: Static preview with separate placement step
#### UI Organization
- **YAZE**: Fixed-width columns prevent layout disruption
- **ZScream**: Resizable panels that can affect overall layout
#### Caching Strategy
- **YAZE**: Sophisticated object render caching with hash-based invalidation
- **ZScream**: Simpler caching approach
### Shared Concepts
Both systems share fundamental concepts:
- Object-based room construction
- Layer-based rendering

# Emulator Core Improvements Roadmap
**Last Updated:** October 10, 2025
**Status:** Active Planning
## Overview
This document outlines improvements, refactors, and optimizations for the yaze emulator core. These changes aim to enhance accuracy, performance, and code maintainability.
Items are presented in order of descending priority, from critical accuracy fixes to quality-of-life improvements.
---
## Critical Priority: APU Timing Fix
### Problem Statement
The emulator's Audio Processing Unit (APU) currently fails to load and play music. Analysis shows that the SPC700 processor gets "stuck" during the initial handshake sequence with the main CPU. This handshake is responsible for uploading the sound driver from ROM to APU RAM. The failure of this timing-sensitive process prevents the sound driver from running.
### Root Cause: CPU-APU Handshake Timing
The process of starting the APU and loading a sound bank requires tightly synchronized communication between the main CPU (65816) and the APU's CPU (SPC700).
#### The Handshake Protocol
1. **APU Ready**: SPC700 boots, initializes, signals ready by writing `$AA` to port `$F4` and `$BB` to port `$F5`
2. **CPU Waits**: Main CPU waits in tight loop, reading combined 16-bit value from I/O ports until it sees `$BBAA`
3. **CPU Initiates**: CPU writes command code `$CC` to APU's input port
4. **APU Acknowledges**: SPC700 sees `$CC` and prepares to receive data block
5. **Synchronized Byte Transfer**: CPU and APU enter lock-step loop to transfer sound driver byte-by-byte:
* CPU sends data
* CPU waits for APU to read data and echo back confirmation
* Only upon receiving confirmation does CPU send next byte
#### Point of Failure
The "stuck" behavior occurs because one side fails to meet the other's expectation. Due to timing desynchronization:
* The SPC700 is waiting for a byte that the CPU has not yet sent (or sent too early), OR
* The CPU is waiting for an acknowledgment that the SPC700 has already sent (or has not yet sent)
The result is an infinite loop on the SPC700, detected by the watchdog timer in `Apu::RunCycles`.
### Technical Analysis
The handshake's reliance on precise timing exposes inaccuracies in the current SPC700 emulation model.
#### Issue 1: Incomplete Opcode Timing
The emulator uses a static lookup table (`spc700_cycles.h`) for instruction cycle counts. This provides a *base* value but fails to account for:
* **Addressing Modes**: Different addressing modes have different cycle costs
* **Page Boundaries**: Memory accesses crossing 256-byte page boundaries take an extra cycle
* **Branching**: Conditional branches take different cycle counts depending on whether branch is taken
While some of this is handled (e.g., `DoBranch`), it is not applied universally, leading to small, cumulative errors.
#### Issue 2: Fragile Multi-Step Execution Model
The `step`/`bstep` mechanism in `Spc700::RunOpcode` is a significant source of fragility. It attempts to model complex instructions by spreading execution across multiple calls. This means the full cycle cost of an instruction is not consumed atomically. An off-by-one error in any step corrupts the timing of the entire APU.
#### Issue 3: Floating-Point Precision
The use of `double` for the `apuCyclesPerMaster` ratio can introduce minute floating-point precision errors. Over thousands of cycles required for the handshake, these small errors accumulate and contribute to timing drift between CPU and APU.
### Proposed Solution: Cycle-Accurate Refactoring
#### Step 1: Implement Cycle-Accurate Instruction Execution
The `Spc700::RunOpcode` function must be refactored to calculate and consume the *exact* cycle count for each instruction *before* execution.
* **Calculate Exact Cost**: Before running an opcode, determine its precise cycle cost by analyzing opcode, addressing mode, and potential page-boundary penalties
* **Atomic Execution**: Remove the `bstep` mechanism. An instruction, no matter how complex, should be fully executed within a single call to a new `Spc700::Step()` function
#### Step 2: Centralize the APU Execution Loop
The main `Apu::RunCycles` loop should be the sole driver of APU time.
* **Cycle Budget**: At the start of a frame, calculate the total "budget" of APU cycles needed
* **Cycle-by-Cycle Stepping**: Loop, calling `Spc700::Step()` and `Dsp::Cycle()`, decrementing cycle budget until exhausted
**Example of the new loop in `Apu::RunCycles`:**
```cpp
void Apu::RunCycles(uint64_t master_cycles) {
// 1. Calculate cycle budget for this frame
const uint64_t target_apu_cycles = ...;
// 2. Run the APU until the budget is met
while (cycles_ < target_apu_cycles) {
// 3. Execute one SPC700 cycle/instruction and get its true cost
int spc_cycles_consumed = spc700_.Step();
// 4. Advance DSP and Timers for each cycle consumed
for (int i = 0; i < spc_cycles_consumed; ++i) {
Cycle(); // This ticks the DSP and timers
}
}
}
```
#### Step 3: Use Integer-Based Cycle Ratios
To eliminate floating-point errors, convert the `apuCyclesPerMaster` ratio to a fixed-point integer ratio. This provides perfect, drift-free conversion between main CPU and APU cycles over long periods.
---
## High Priority: Core Architecture & Timing Model
### CPU Cycle Counting
* **Issue:** The main CPU loop in `Snes::RunCycle()` advances the master cycle counter by a fixed amount (`+= 2`). Real 65816 instructions have variable cycle counts. The current workaround of scattering `callbacks_.idle()` calls is error-prone and difficult to maintain.
* **Recommendation:** Refactor `Cpu::ExecuteInstruction` to calculate and return the *precise* cycle cost of each instruction, including penalties for addressing modes and memory access speeds. The main `Snes` loop should then consume this exact value, centralizing timing logic and dramatically improving accuracy.
### Main Synchronization Loop
* **Issue:** The main loop in `Snes::RunFrame()` is state-driven based on the `in_vblank_` flag. This can be fragile and makes it difficult to reason about component state at any given cycle.
* **Recommendation:** Transition to a unified main loop driven by a single master cycle counter. In this model, each component (CPU, PPU, APU, DMA) is "ticked" forward based on the master clock. This is a more robust and modular architecture that simplifies component synchronization.
---
## Medium Priority: PPU Performance
### Rendering Approach Optimization
* **Issue:** The PPU currently uses a "pixel-based" renderer (`Ppu::RunLine` calls `HandlePixel` for every pixel). This is highly accurate but can be slow due to high function call overhead and poor cache locality.
* **Optimization:** Refactor the PPU to use a **scanline-based renderer**. Instead of processing one pixel at a time, process all active layers for an entire horizontal scanline, compose them into a temporary buffer, and then write the completed scanline to the framebuffer. This is a major architectural change but is a standard and highly effective optimization technique in SNES emulation.
**Benefits:**
- Reduced function call overhead
- Better cache locality
- Easier to vectorize/SIMD
- Standard approach in accurate SNES emulators
---
## Low Priority: Code Quality & Refinements
### APU Code Modernization
* **Issue:** The code in `dsp.cc` and `spc700.cc`, inherited from other projects, is written in a very C-like style, using raw pointers, `memset`, and numerous "magic numbers."
* **Refactor:** Gradually refactor this code to use modern C++ idioms:
- Replace raw arrays with `std::array`
- Use constructors with member initializers instead of `memset`
- Define `constexpr` variables or `enum class` types for hardware registers and flags
- Improve type safety, readability, and long-term maintainability
### Audio Subsystem & Buffering
* **Issue:** The current implementation in `Emulator::Run` queues audio samples directly to the SDL audio device. If the emulator lags for even a few frames, the audio buffer can underrun, causing audible pops and stutters.
* **Improvement:** Implement a **lock-free ring buffer (or circular buffer)** to act as an intermediary. The emulator thread would continuously write generated samples into this buffer, while the audio device (in its own thread) would continuously read from it. This decouples the emulation speed from the audio hardware, smoothing out performance fluctuations and preventing stutter.
### Debugger & Tooling Optimizations
#### DisassemblyViewer Data Structure
* **Issue:** `DisassemblyViewer` uses a `std::map` to store instruction traces. For a tool that handles frequent insertions and lookups, this can be suboptimal.
* **Optimization:** Replace `std::map` with `std::unordered_map` for faster average-case performance.
#### BreakpointManager Lookups
* **Issue:** The `ShouldBreakOn...` functions perform a linear scan over a `std::vector` of all breakpoints. This is O(n) and could become a minor bottleneck if a very large number of breakpoints are set.
* **Optimization:** For execution breakpoints, use a `std::unordered_set<uint32_t>` for O(1) average lookup time. This would make breakpoint checking near-instantaneous, regardless of how many are active.
---
## Completed Improvements
### Audio System Fixes (v0.4.0)
#### Problem Statement
The SNES emulator experienced audio glitchiness and skips, particularly during the ALTTP title screen, with audible pops, crackling, and sample skipping during music playback.
#### Root Causes Fixed
1. **Aggressive Sample Dropping**: Audio buffering logic was dropping up to 50% of generated samples, creating discontinuities
2. **Incorrect Resampling**: Duplicate calculations in linear interpolation wasted CPU cycles
3. **Missing Frame Synchronization**: DSP's `NewFrame()` method was never called, causing timing drift
4. **Missing Hermite Interpolation**: Only Linear/Cosine/Cubic were available (Hermite is the industry standard)
#### Solutions Implemented
1. **Never Drop Samples**: Always queue all generated samples unless buffer critically full (>4 frames)
2. **Fixed Resampling Code**: Removed duplicate calculations and added bounds checking
3. **Frame Boundary Synchronization**: Added `dsp.NewFrame()` call before sample generation
4. **Hermite Interpolation**: New interpolation type matching bsnes/Snes9x standard
**Interpolation options** (`src/app/emu/audio/dsp.cc`):
| Interpolation | Notes |
|--------------|-------|
| Linear | Fastest; retains legacy behaviour. |
| Hermite | New default; balances quality and speed. |
| Cosine | Smoother than linear with moderate cost. |
| Cubic | Highest quality, heavier CPU cost. |
**Result**: Manual testing on the ALTTP title screen, overworld theme, dungeon ambience, and menu sounds no longer exhibits audible pops or skips. Continue to monitor regression tests after the APU timing refactor lands.
---
## Implementation Priority
1. **Critical (v0.4.0):** APU timing fix - Required for music playback
2. **High (v0.5.0):** CPU cycle counting accuracy - Required for game compatibility
3. **High (v0.5.0):** Main synchronization loop refactor - Foundation for accuracy
4. **Medium (v0.6.0):** PPU scanline renderer - Performance optimization
5. **Low (ongoing):** Code quality improvements - Technical debt reduction

```bash
./yaze --rom_file=/path/to/zelda3.sfc
```
### `--debug`
Enable debug logging with verbose output.
```bash
./yaze --debug --log_file=yaze_debug.log
```
### `--editor`
Open a specific editor on startup. This saves time by skipping manual navigation through the UI.

./yaze --rom_file=zelda3.sfc --editor=Dungeon
```
### `--cards`
Open specific cards/panels within an editor. Most useful with the Dungeon editor.
**Dungeon Editor Cards:**
- `Rooms List` - Shows the list of all dungeon rooms
- `Room Matrix` - Shows the dungeon room layout matrix
- `Entrances List` - Shows dungeon entrance configurations
- `Room Graphics` - Shows room graphics settings
- `Object Editor` - Shows the object placement editor
- `Palette Editor` - Shows the palette editor
- `Room N` - Opens a specific room by ID (e.g., `Room 0`, `Room 105`)
**Example:**
```bash
./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Rooms List,Room 0"
```
## Common Debugging Scenarios
### 1. Quick Dungeon Room Testing
Open a specific dungeon room for testing:
```bash
./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0,Room Graphics"
```
### 2. Multiple Room Comparison
Compare multiple rooms side-by-side:
```bash
./yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0,Room 1,Room 105"
```
### 3. Full Dungeon Editor Workspace
Open all dungeon editor tools:
```bash
./yaze --rom_file=zelda3.sfc --editor=Dungeon \
--cards="Rooms List,Room Matrix,Room Graphics,Object Editor,Palette Editor"
```
### 4. Debug Mode with Logging
Enable full debug output while working:
```bash
./yaze --rom_file=zelda3.sfc --debug --log_file=debug.log \
--editor=Dungeon --cards="Room 0"
```
### 5. Quick Overworld Editing
Jump straight to overworld editing:
```bash
./yaze --rom_file=zelda3.sfc --editor=Overworld
```
## gRPC Test Harness (Developer Feature)
If compiled with `YAZE_WITH_GRPC=ON`, you can enable automated GUI testing:
```bash
./yaze --enable_test_harness --test_harness_port=50051
```
This allows remote control via gRPC for automated testing and AI agent interaction.
## Combining Flags
All flags can be combined for powerful debugging setups:
```bash
# Full debugging setup for room 105
./yaze \
--rom_file=/path/to/zelda3.sfc \
--debug \
--log_file=room_105_debug.log \
--editor=Dungeon \
--cards="Room 105,Room Graphics,Palette Editor,Object Editor"
```
## Notes
- Card names are case-sensitive and must match exactly
- Use quotes around comma-separated card lists
- Invalid editor or card names will be logged as warnings but won't crash the application
- The `--cards` flag is currently only implemented for the Dungeon editor
- Room IDs range from 0-319 in the vanilla game
## Troubleshooting
**Editor doesn't open:**
- Check spelling (case-sensitive)
- Verify ROM loaded successfully
- Check log output with `--debug`
**Cards don't appear:**
- Ensure editor is set (e.g., `--editor=Dungeon`)
- Check card name spelling
- Some cards require a loaded ROM
**Want to add more card support?**
See `EditorManager::OpenEditorAndCardsFromFlags()` in `src/app/editor/editor_manager.cc`

## Real-World Example: Debugging ALTTP Input Issues
### Problem Statement
ALTTP's name entry screen doesn't respond to A button presses. Other screens work fine. This suggests an edge-triggered input detection issue specific to the name entry menu.
### AI Agent Debugging Session
**Step 1: Set up observation points**
```bash
# AI Agent: "Let's monitor where ALTTP reads joypad data"
# Set breakpoint at NMI_ReadJoypads routine
z3ed emulator set-breakpoint --address 0x0083D7 --type execute \
--description "NMI_ReadJoypads entry"
# Set breakpoint at name entry input check
z3ed emulator set-breakpoint --address 0x00CDB2A --type execute \
--description "Name entry input handler"
```
**Step 2: Monitor joypad WRAM variables**
```bash
# AI Agent: "I'll watch the joypad state variables during input"
# Watch $F4 (newly pressed buttons - high byte)
z3ed emulator read-memory --address 0x7E00F4 --length 1
# Watch $F6 (newly pressed buttons - low byte, includes A button)
z3ed emulator read-memory --address 0x7E00F6 --length 1
# Watch $4218/$4219 (hardware auto-joypad registers)
z3ed emulator read-memory --address 0x4218 --length 2
```
**Step 3: Single-step through NMI routine**
```bash
# AI Agent: "Let's trace the NMI execution when A is pressed"
# Pause emulator
z3ed emulator pause
# Step through NMI_ReadJoypads
for i in {1..20}; do
z3ed emulator step
z3ed emulator get-registers | jq '.PC'
z3ed emulator read-memory --address 0x7E00F6 --length 1
done
```
**Step 4: Compare auto-joypad vs manual reads**
```bash
# AI Agent: "The hardware specs say $4218 is populated by auto-joypad read"
# AI Agent: "Let's check if auto-joypad is enabled"
# Read $4200 (NMITIMEN - auto-joypad enable bit 0)
z3ed emulator read-memory --address 0x4200 --length 1
# If auto-joypad is enabled, check timing
# Set breakpoint when $4218 is populated
z3ed emulator set-breakpoint --address 0x004218 --type write \
--description "Auto-joypad data written"
```
**Step 5: Identify root cause**
```bash
# AI Agent discovers:
# 1. current_state_ = 0x0100 (A button at bit 8) ✓
# 2. port_auto_read[0] = 0x0080 (bit 7) ✗ BUG!
# 3. The bit-reversal loop shifts A from bit 8→bit 7
# 4. Game reads $4218 expecting A at bit 7 (per hardware spec)
# 5. But our mapping puts A at bit 8, which becomes bit 7 after reversal!
# Solution: Check button bit positions in current_state_
z3ed emulator read-memory --address <input1.current_state_> --length 2
```
### Findings
The AI agent can systematically:
1. Set breakpoints at critical routines
2. Monitor WRAM variables frame-by-frame
3. Step through assembly code execution
4. Compare hardware register values
5. Identify timing discrepancies
6. Root-cause bit mapping bugs
## Advanced Use Cases
### Watchpoints for Input Debugging
```bash
# Watch when $F4/$F6 are written (edge-detection happens here)
z3ed emulator add-watchpoint --address 0x7E00F4 --length 4 \
--track-writes --break-on-access \
--description "Joypad edge-detection WRAM"
# Get access history
z3ed emulator get-watchpoint-history --id 1 --max-entries 100
```
### Symbol-Based Debugging (with Oracle of Secrets disassembly)
```bash
# Load symbols from disassembly
z3ed emulator load-symbols --file assets/asm/alttp/bank_00.sym --format asar
# Set breakpoint by symbol name
z3ed emulator set-breakpoint --symbol "NMI_ReadJoypads"
# Resolve symbol at runtime
z3ed emulator get-symbol-at --address 0x0083D7
# Output: "NMI_ReadJoypads"
```
### Automated Test Scripts
The AI can generate debugging scripts:
```bash
#!/bin/bash
# debug_name_entry_input.sh
# Generated by AI agent to systematically test input flow
echo "=== ALTTP Name Entry Input Debug Script ==="
# 1. Start emulator and navigate to name entry screen
z3ed emulator run --rom zelda3.sfc
z3ed emulator press-buttons --buttons START # Get to file select
sleep 1
z3ed emulator press-buttons --buttons A # Select new game
sleep 2 # Wait for name entry screen
# 2. Set up monitoring
z3ed emulator set-breakpoint --address 0x0083D7 --description "NMI read"
z3ed emulator set-breakpoint --address 0x00CDB2A --description "Name entry input"
# 3. Test A button press with monitoring
echo "Pressing A button..."
z3ed emulator press-buttons --buttons A
# 4. Check state immediately after
z3ed emulator read-memory --address 0x7E00F4 --length 4 --format json > joypad_state.json
z3ed emulator read-memory --address 0x4218 --length 2 >> joypad_state.json
z3ed emulator get-registers >> joypad_state.json
# 5. Analyze results
echo "Results saved to joypad_state.json"
cat joypad_state.json | jq '.'
```
## Benefits for AI-Driven Debugging
### Before (Manual Print Debugging)
1. Add `LOG_DEBUG()` statements manually
2. Rebuild C++ code (slow)
3. Run emulator and capture logs
4. Parse terminal output
5. Iterate with more logging
6. **Requires C++ knowledge and build tools**
### After (AI Agent with gRPC Service)
1. AI asks: "Why doesn't A button work in name entry?"
2. AI uses tools to inspect memory and set breakpoints
3. AI steps through execution and reads state
4. AI identifies discrepancy (bit 7 vs bit 8)
5. AI suggests fix or generates test case
6. **No rebuild needed, works from CLI or chat**
## Integration with Agent Chat Widget
The same gRPC service is accessible from the Agent Chat widget inside YAZE:
```
User: "Debug why A button doesn't work in name entry screen"
AI: I'll set up monitoring for the joypad input flow.
[Calling: emulator-set-breakpoint address=0x0083D7]
✓ Breakpoint 1 set at NMI_ReadJoypads
[Calling: emulator-read-memory address=0x7E00F4 length=4]
✓ Read joypad WRAM: F4=00 F5=00 F6=00 F7=00
Now press the A button...
[Calling: emulator-read-memory address=0x4218 length=2]
✓ Auto-joypad registers: $4218=00 $4219=00
I see the issue! The auto-joypad registers are reading zero even though
current_state_ has the A button set. Let me check the HandleInput()
function...
[Calling: emulator-get-registers]
✓ PC=$00:83D7 (inside NMI_ReadJoypads)
The game is reading $4218 at PC=$83D7, but port_auto_read[0] is empty.
This suggests HandleInput() isn't being called before the NMI routine,
or the auto-joypad data is being cleared prematurely.
```

## Practical Debugging Workflow
### Scenario: Input Button Not Registering
**Problem**: A button works on title screen but not on name entry screen.
**AI Agent Approach**:
1. **Hypothesis Formation**
```
AI: The A button works elsewhere, so the input backend is functional.
The name entry screen likely uses edge-triggered input detection.
Let's verify where the game reads input state.
```
2. **Set Observation Points**
```bash
z3ed emulator set-breakpoint --address 0x0083D7 --description "NMI start"
z3ed emulator set-breakpoint --address 0x00CDB2A --description "Name entry input check"
```
3. **Monitor Key Variables**
```bash
# Check if auto-joypad is enabled
z3ed emulator read-memory --address 0x4200 --length 1
# Output: 0x81 (NMI=1, AutoJoy=1) ✓
# Check current controller state
z3ed emulator read-memory --address <input1.current_state_> --length 2
# Output: 0x0100 (A button active) ✓
# Check auto-joypad registers
z3ed emulator read-memory --address 0x4218 --length 2
# Output: 0x0000 (EMPTY!) ✗
```
4. **Step Through Critical Code**
```bash
# Run until breakpoint
z3ed emulator run --until-break
# Hit: Breakpoint 1 at 0x0083D7 (NMI_ReadJoypads)
# Step through the LDA $4218 instruction
z3ed emulator step
z3ed emulator get-registers
# PC=0x83DA, A=0x00 (loaded zero from $4218!)
```
5. **Root Cause Analysis**
```
AI: The game's NMI routine reads $4218 and gets zero, even though
current_state_=0x0100. This means HandleInput() either:
a) Isn't being called before NMI
b) Is clearing port_auto_read[] multiple times
c) Has a bit mapping bug
Let's check HandleInput() call frequency...
```
6. **Verification**
```bash
# Set watchpoint on port_auto_read[] writes
z3ed emulator add-watchpoint --address <port_auto_read_> --length 8 \
--track-writes --description "Auto-joypad buffer writes"
# Get history to see how many times it's written per frame
z3ed emulator get-watchpoint-history --id 1 --max-entries 100
# AI discovers: HandleInput() is called 10+ times per frame!
# Each call clears port_auto_read[], so by the time NMI reads it, it's empty.
```
### Solution Discovery
The AI can propose fixes:
```
AI: The root cause is that HandleInput() clears port_auto_read[] at the start,
and it's being called multiple times per frame. By the time the NMI reads
$4218/$4219, the data has been cleared by a subsequent HandleInput() call.
Solution: HandleInput() should only be called ONCE per VBlank, not continuously.
Would you like me to:
a) Generate a patch for snes.cc to fix the timing
b) Create a test case to verify the fix
c) Add a watchpoint to monitor when port_auto_read[] is written
```
## Comparison: Print Debugging vs AI-Driven Debugging
| Aspect | Print Debugging | AI Agent Debugging |
|--------|----------------|-------------------|
| **Time to first hypothesis** | Hours (requires code reading) | Minutes (AI analyzes structure) |
| **Iteration speed** | Slow (edit→rebuild→run) | Fast (set breakpoint→read state) |
| **Code knowledge required** | High (C++ emulator internals) | Low (AI translates to tool calls) |
| **Reproducibility** | Poor (manual steps) | Excellent (scripted tool sequence) |
| **Collaboration** | Hard (share logs) | Easy (share tool call JSON) |
| **Learning curve** | Steep (emulator architecture) | Gentle (natural language questions) |
## Performance Impact
### Memory Overhead
- **BreakpointManager**: ~50 bytes per breakpoint
- **DisassemblyViewer**: ~100 bytes per recorded instruction (sparse map)
- **gRPC Service**: ~1KB base overhead
- **Total**: Negligible (<1MB for typical debugging session)
### CPU Overhead
- Breakpoint checking: ~1 cycle per execute breakpoint per instruction
- Memory watchpoints: ~2-5 cycles per memory access (when integrated)
- Disassembly recording: ~10 cycles per instruction (when enabled)
- **Impact**: <1% on 60 FPS target
### Network Latency
- gRPC call latency: 1-5ms (local)
- Step + GetState round-trip: ~10ms
- Acceptable for interactive debugging (not real-time gameplay)
## Future Enhancements
### Phase 2 (Next 2-4 weeks)
1. **WatchpointManager Integration**
- Add `watchpoint_manager_` to `Emulator` class
- Implement memory access hooks in `Snes::Read/Write`
- Complete watchpoint gRPC methods
- Add CLI command handlers
2. **Symbol Management**
- Load .sym files from Asar/WLA-DX
- Resolve symbols to addresses
- Reverse lookup (address → symbol name)
- Integration with Oracle of Secrets disassembly
3. **Execution Trace**
- Ring buffer for last N instructions
- Export to JSON/CSV
- Hotpath analysis
- Call stack reconstruction
4. **Step Over/Step Out**
- Track JSR/JSL calls
- Automatically run until RTS/RTL
- Nested call depth tracking
### Phase 3 (1-2 months)
1. **Time-Travel Debugging**
- Record full execution state
- Replay from savepoints
- Reverse execution
2. **Performance Profiling**
- Instruction-level profiling
- Memory access heatmaps
- Function call graphs
3. **AI Test Generation**
- Auto-generate test cases from debugging sessions
- Regression test suites
- Automated bisection for bug finding
## AI Agent System Prompt Extension
Add this to the AI's system prompt for emulator debugging:
```
You have access to a comprehensive SNES emulator debugging service via gRPC.
When investigating emulation bugs or game behavior:
1. Set breakpoints at key routines (NMI, input handlers, game logic)
2. Monitor critical WRAM variables ($F4/$F6 for input, $0010 for game mode)
3. Read hardware registers ($4xxx) to check peripheral state
4. Step through assembly execution to trace data flow
5. Use watchpoints to find where variables are modified
6. Compare expected vs actual values at each step
For input issues specifically:
- Check $4200 bit 0 (auto-joypad enable)
- Monitor $4218/$4219 (auto-joypad data registers)
- Watch $F4/$F6 (WRAM joypad state populated by NMI)
- Verify current_state_ → port_auto_read[] → $4218 data flow
Always prefer using debugging tools over print statements. Generate scripts
for reproducible debugging sessions.

# F2: Dungeon Editor v2 - Complete Guide
**Last Updated**: October 10, 2025
**Related**: [E2-development-guide.md](E2-development-guide.md), [E5-debugging-guide.md](E5-debugging-guide.md)
---
## Overview
The Dungeon Editor uses a modern card-based architecture (DungeonEditorV2) with self-contained room rendering. This guide covers the architecture, recent refactoring work, and next development steps.
### Key Features
- **Visual room editing** with 512x512 canvas per room
- **Object position visualization** - Colored outlines by layer (Red/Green/Blue)
- **Per-room settings** - Independent BG1/BG2 visibility and layer types
- **Flexible docking** - EditorCard system for custom workspace layouts
- **Self-contained rooms** - Each room owns its bitmaps and palettes
- **Overworld integration** - Double-click entrances to open dungeon rooms
---
### Architecture Improvements
1. **Room Buffers Decoupled** - No dependency on Arena graphics sheets
2. **ObjectRenderer Removed** - Standardized on ObjectDrawer (~1000 lines deleted)
3. **LoadGraphicsSheetsIntoArena Removed** - Using per-room graphics (~66 lines)
4. **Old Tab System Removed** - EditorCard is the standard
5. **Texture Atlas Infrastructure** - Future-proof stub created
6. **Test Suite Cleaned** - Deleted 1270 lines of redundant tests
### UI Improvements
- Room ID in card title: `[003] Room Name`
- Properties reorganized into clean 4-column table
- Compact layer controls (1 row instead of 3)
- Room graphics canvas height fixed (1025px → 257px)
- Object count in status bar
---
## Architecture
### Component Overview
```
DungeonEditorV2 (UI Layer)
├─ Card-based UI system
├─ Room window management
├─ Component coordination
└─ Lazy loading
DungeonEditorSystem (Backend Layer)
├─ Sprite/Item/Entrance/Door/Chest management
├─ Undo/Redo functionality
├─ Room properties management
└─ Dungeon-wide operations
Room (Data Layer)
├─ Self-contained buffers (bg1_buffer_, bg2_buffer_)
├─ Object storage (tile_objects_)
├─ Graphics loading
└─ Rendering pipeline
```
### Room Rendering Pipeline
TODO: Update this to latest code.
```
1. LoadRoomGraphics(blockset)
└─> Reads blocks[] from ROM
└─> Loads blockset data → current_gfx16_
2. LoadObjects()
└─> Parses object data from ROM
└─> Creates tile_objects_[]
└─> SETS floor1_graphics_, floor2_graphics_ ← CRITICAL!
3. RenderRoomGraphics() [SELF-CONTAINED]
├─> DrawFloor(floor1_graphics_, floor2_graphics_)
├─> DrawBackground(current_gfx16_)
├─> SetPalette(full_90_color_dungeon_palette)
├─> RenderObjectsToBackground()
│ └─> ObjectDrawer::DrawObjectList()
└─> QueueTextureCommand(UPDATE/CREATE)
4. DrawRoomBackgroundLayers(room_id)
└─> ProcessTextureQueue() → GPU textures
└─> canvas_.DrawBitmap(bg1, bg2)
5. DrawObjectPositionOutlines(room)
└─> Colored rectangles by layer
└─> Object ID labels
```
### Room Structure (Bottom to Top)
Understanding ALTTP dungeon composition is critical:
```
Room Composition:
├─ Room Layout (BASE LAYER - immovable)
│ ├─ Walls (structural boundaries, 7 configurations of squares in 2x2 grid)
│ ├─ Floors (walkable areas, repeated tile pattern set to BG1/BG2)
├─ Layer 0 Objects (floor decorations, some walls)
├─ Layer 1 Objects (chests, decorations)
└─ Layer 2 Objects (stairs, transitions)
Doors: Positioned at room edges to connect rooms
```
**Key Insight**: Layouts are immovable base structure. Objects are placed ON TOP and can be moved/edited. This allows for large rooms, 4-quadrant rooms, tall/wide rooms, etc.
---
## Next Development Steps
### High Priority (Must Do)
#### 1. Door Rendering at Room Edges
**What**: Render doors with proper patterns at room connections
**Pattern Reference**: ZScream's door drawing patterns
**Implementation**:
```cpp
void DungeonCanvasViewer::DrawDoors(const zelda3::Room& room) {
// Doors stored in room data
// Position at room edges (North/South/East/West)
// Use current_gfx16_ graphics data
// TODO: Get door data from room.GetDoors() or similar
// TODO: Use ObjectDrawer patterns for door graphics
// TODO: Draw at interpolation points between rooms
}
```
---
#### 2. Object Name Labels from String Array
**File**: `dungeon_canvas_viewer.cc:416` (DrawObjectPositionOutlines)
**What**: Show real object names instead of just IDs
**Implementation**:
```cpp
// Instead of:
std::string label = absl::StrFormat("0x%02X", obj.id_);
// Use:
std::string object_name = GetObjectName(obj.id_);
std::string label = absl::StrFormat("%s\n0x%02X", object_name.c_str(), obj.id_);
// Helper function:
std::string GetObjectName(int16_t object_id) {
// TODO: Reference ZScream's object name arrays
// TODO: Map object ID → name string
// Example: 0x10 → "Wall (North)"
return "Object";
}
```
---
#### 4. Fix Plus Button to Select Any Room
**File**: `dungeon_editor_v2.cc:228` (DrawToolset)
**Current Issue**: Opens Room 0x00 (Ganon) always
**Fix**:
```cpp
if (toolbar.AddAction(ICON_MD_ADD, "Open Room")) {
// Show room selector dialog instead of opening room 0
show_room_selector_ = true;
// Or: show room picker popup
ImGui::OpenPopup("SelectRoomToOpen");
}
// Add popup:
if (ImGui::BeginPopup("SelectRoomToOpen")) {
static int selected_room = 0;
ImGui::InputInt("Room ID", &selected_room);
if (ImGui::Button("Open")) {
OnRoomSelected(selected_room);
ImGui::CloseCurrentPopup();
}
ImGui::EndPopup();
}
```
---
### Medium Priority (Should Do)
#### 6. Fix InputHexByte +/- Button Events
**File**: `src/app/gui/input.cc` (likely)
**Issue**: Buttons don't respond to clicks
**Investigation Needed**:
- Check if button click events are being captured
- Verify event logic matches working examples
- Keep existing event style if it works elsewhere
### Lower Priority (Nice to Have)
#### 9. Move Backend Logic to DungeonEditorSystem
**What**: Separate UI (V2) from data operations (System)
**Migration**:
- Sprite management → DungeonEditorSystem
- Item management → DungeonEditorSystem
- Entrance/Door/Chest → DungeonEditorSystem
- Undo/Redo → DungeonEditorSystem
**Result**: DungeonEditorV2 becomes pure UI coordinator
---
## Quick Start
### Build & Run
```bash
cd /Users/scawful/Code/yaze
cmake --preset mac-ai -B build_ai
cmake --build build_ai --target yaze -j12

# Open specific room
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0x00"
```
---
## Testing & Verification
### Debug Commands
```bash
# Verify floor values load correctly
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon 2>&1 | grep "floor1="
# Expected: floor1=4, floor2=8 (NOT 0!)
# Check object rendering
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon 2>&1 | grep "Drawing.*objects"

# Tile16 Editor Palette System
**Status: Work in Progress** - Documentation for the ongoing Tile16 Editor palette system redesign, implementation, and refactoring improvements.
## Executive Summary
The tile16 editor palette system is undergoing a complete redesign to resolve critical crashes and ensure proper color alignment between the tile16 editor and overworld display. Significant progress has been made addressing fundamental architectural issues with palette mapping, implementing crash fixes, and creating an improved three-column layout. However, palette handling for the tile8 source canvas and palette button functionality remain works in progress.
## Problem Analysis
### Critical Issues Identified
1. **SIGBUS Crash in SnesColor::rgb()**
- **Root Cause**: `SetPaletteWithTransparent()` method used incorrect `index * 7` calculation
- **Impact**: Crashes when selecting palette buttons 4-7 due to out-of-bounds memory access
- **Location**: `bitmap.cc:371` - `start_index = index * 7`
2. **Fundamental Architecture Misunderstanding**
- **Root Cause**: Attempting to use `SetPaletteWithTransparent()` instead of `SetPalette()`
- **Impact**: Broke the 256-color palette system that the overworld relies on
- **Reality**: Overworld system uses complete 256-color palettes with `SetPalette()`
3. **Color Mapping Misunderstanding**
- **Root Cause**: Confusion about how color mapping works in the graphics system
- **Impact**: Incorrect palette handling in tile16 editor
- **Reality**: Pixel data already contains correct color indices for the 256-color palette
## Solution Architecture
### Core Design Principles
1. **Use Same Palette System as Overworld**: Use `SetPalette()` with complete 256-color palette
2. **Direct Color Mapping**: The pixel data in graphics already contains correct color indices that map to the 256-color palette
3. **Proper Bounds Checking**: Prevent out-of-bounds memory access in palette operations
4. **Consistent Architecture**: Match overworld editor's palette handling exactly
### 256-Color Overworld Palette Structure
Based on analysis of `SetColorsPalette()` in `overworld_map.cc`:
```
Row 0-1: HUD palette (32 colors) - Slots 0-31
Row 2-6: MAIN palette (35 colors) - Slots 32-87 (rows 2-6, cols 1-7)
Row 7: ANIMATED palette (7 colors) - Slots 112-118 (row 7, cols 1-7)
Row 8: Sprite AUX1 + AUX3 (14 colors) - Slots 128-141
Row 9-12: Global sprites (60 colors) - Slots 144-203
Row 13: Sprite palette 1 (7 colors) - Slots 208-214
Row 14: Sprite palette 2 (7 colors) - Slots 224-230
Row 15: Armor palettes (15 colors) - Slots 240-254
Right side (cols 9-15):
Row 2-4: AUX1 palette (21 colors) - Slots 136-151
Row 5-7: AUX2 palette (21 colors) - Slots 152-167
```
### Sheet-to-Palette Mapping
```
Sheet 0,3,4: → AUX1 region (slots 136-151)
Sheet 5,6: → AUX2 region (slots 152-167)
Sheet 1,2: → MAIN region (slots 32-87)
Sheet 7: → ANIMATED region (slots 112-118)
```
### Palette Button Mapping
| Button | Sheet 0,3,4 (AUX1) | Sheet 1,2 (MAIN) | Sheet 5,6 (AUX2) | Sheet 7 (ANIMATED) |
|--------|---------------------|-------------------|-------------------|---------------------|
| 0 | 136 | 32 | 152 | 112 |
| 1 | 138 | 39 | 154 | 113 |
| 2 | 140 | 46 | 156 | 114 |
| 3 | 142 | 53 | 158 | 115 |
| 4 | 144 | 60 | 160 | 116 |
| 5 | 146 | 67 | 162 | 117 |
| 6 | 148 | 74 | 164 | 118 |
| 7 | 150 | 81 | 166 | 119 |
## Implementation Details
### 1. Fixed SetPaletteWithTransparent Method
**File**: `src/app/gfx/bitmap.cc`
**Before**:
```cpp
auto start_index = index * 7; // WRONG: Creates invalid indices for buttons 4-7
```
**After**:
```cpp
// Extract 8-color sub-palette starting at the specified index
// Always start with transparent color (index 0)
colors.push_back(ImVec4(0, 0, 0, 0));
// Extract up to 7 colors from the palette starting at index
for (size_t i = 0; i < 7 && (index + i) < palette.size(); ++i) {
auto &pal_color = palette[index + i];
colors.push_back(pal_color.rgb());
}
```
### 2. Corrected Tile16 Editor Palette System
**File**: `src/app/editor/overworld/tile16_editor.cc`
**Before**:
```cpp
// WRONG: Trying to extract 8-color sub-palettes
current_gfx_individual_[i].SetPaletteWithTransparent(display_palette, base_palette_slot, 8);
```
**After**:
```cpp
// CORRECT: Use complete 256-color palette (same as overworld system)
// The pixel data already contains correct color indices for the 256-color palette
current_gfx_individual_[i].SetPalette(display_palette);
```
### 3. Palette Coordination Flow
```
Overworld System:
ProcessGraphicsBuffer() → adds 0x88 offset to sheets 0,3,4,5
BuildTiles16Gfx() → combines with palette info
current_gfx_bmp_ → contains properly offset pixel data
Tile16 Editor:
Initialize() → receives current_gfx_bmp_ with correct data
LoadTile8() → extracts tiles with existing pixel values
SetPalette() → applies complete 256-color palette
Display → correct colors shown automatically
```
## UI/UX Refactoring
### New Three-Column Layout
The tile16 editor layout was completely restructured into a unified 3-column table for better space utilization:
**Column 1: Tile16 Blockset** (35% width)
- Complete 512-tile blockset display
- Integrated zoom slider (0.5x - 4.0x)
- Zoom in/out buttons for quick adjustments
- Click to select tiles for editing
- Full vertical scrolling support
**Column 2: Tile8 Source Tileset** (35% width)
- All 8x8 source tiles
- Palette group selector (OW Main, OW Aux, etc.)
- Integrated zoom slider (1.0x - 8.0x)
- Click to select tiles for painting
- Full vertical scrolling support
**Column 3: Editor & Controls** (30% width)
- Tile16 editor canvas with dynamic zoom (2.0x - 8.0x)
- Canvas size adjusts automatically with zoom level
- All controls in compact vertical layout:
- Tile8 preview and ID
- Flip controls (X, Y, Priority)
- Palette selector (8 buttons)
- Action buttons (Clear, Copy, Paste)
- Save/Discard changes
- Undo button
- Advanced controls (collapsible)
- Debug information (collapsible)
**Benefits**:
- Better space utilization - all three main components visible simultaneously
- Improved workflow - blockset, source tiles, and editor all in one view
- Resizable columns allow users to adjust layout to preference
### Canvas Context Menu Fixes
**Problem**: The "Advanced Canvas Properties" and "Scaling Controls" popup dialogs were not appearing when selected from the context menu.
**Solution**:
- Changed popup windows from modal popups to regular windows
- Added boolean flags `show_advanced_properties_` and `show_scaling_controls_` to track window state
- Windows now appear as floating windows instead of modal dialogs
- Added public accessor methods:
- `OpenAdvancedProperties()`
- `OpenScalingControls()`
- `CloseAdvancedProperties()`
- `CloseScalingControls()`
**Files Modified**:
- `src/app/gui/canvas.cc` - Updated popup implementation
- `src/app/gui/canvas.h` - Added boolean flags and accessor methods
### Dynamic Zoom Controls
Each canvas now has independent zoom control with real-time feedback:
**Tile16 Blockset Zoom**:
- Range: 0.5x to 4.0x
- Slider control with +/- buttons
- Properly scales mouse coordinate calculations
**Tile8 Source Zoom**:
- Range: 1.0x to 8.0x
- Essential for viewing small pixel details
- Correctly accounts for zoom in tile selection
**Tile16 Editor Zoom**:
- Range: 2.0x to 8.0x
- Canvas size dynamically adjusts with zoom
- Grid scales proportionally
- Mouse coordinates properly transformed
**Implementation Details**:
```cpp
// Mouse coordinate calculations account for dynamic zoom
int tile_x = static_cast<int>(mouse_pos.x / (8 * tile8_zoom));
// Grid drawing scaled with zoom
tile16_edit_canvas_.DrawGrid(8.0F * tile16_zoom / 4.0F);
// Canvas display size calculated dynamically
float canvas_display_size = 16 * tile16_zoom + 4;
```
## Testing Protocol
### Crash Prevention Testing
1. **Load ROM** and open tile16 editor
2. **Test all palette buttons 0-7** - should not crash
3. **Verify color display** - should match overworld appearance
4. **Test different graphics sheets** - should use appropriate palette regions
### Color Alignment Testing
1. **Select tile16 in overworld** - note colors displayed
2. **Open tile16 editor** - load same tile
3. **Test palette buttons 0-7** - colors should match overworld
4. **Verify sheet-specific behavior** - different sheets should show different colors
### UI/UX Testing
1. **Canvas Popups**: Right-click on each canvas → verify "Advanced Properties" and "Scaling Controls" open correctly
2. **Zoom Controls**: Test each zoom slider and button for all three canvases
3. **Tile Selection**: Verify clicking works at various zoom levels for blockset, tile8 source, and tile16 editor
4. **Layout Responsiveness**: Resize window and columns to verify proper behavior
5. **Workflow**: Test complete tile editing workflow from selection to save
## Error Handling
### Bounds Checking
- **Palette Index Validation**: Ensure palette indices don't exceed palette size
- **Sheet Index Validation**: Ensure sheet indices are within valid range (0-7)
- **Surface Validation**: Ensure SDL surface exists before palette operations
### Fallback Mechanisms
- **Default Palette**: Use MAIN region if sheet detection fails
- **Safe Indices**: Clamp palette indices to valid ranges
- **Error Logging**: Comprehensive logging for debugging
## Debug Information Display
The debug panel (collapsible by default) shows:
1. **Current State**: Tile16 ID, Tile8 ID, selected palette button
2. **Mapping Info**: Sheet index, actual palette slot
3. **Reference Table**: Complete button-to-slot mapping for all sheets
4. **Color Preview**: Visual display of actual colors being used
## Known Issues and Ongoing Work
### Completed Items
- **No Crashes**: Fixed SIGBUS errors - palette buttons 0-7 work without crashing
- **Three-Column Layout**: Unified layout with blockset, tile8 source, and editor
- **Dynamic Zoom Controls**: Independent zoom for all three canvases
- **Canvas Popup Fixes**: Advanced properties and scaling controls now working
- **Stable Memory**: No memory leaks or corruption
- **Code Architecture**: Proper bounds checking and error handling
### Active Issues Warning:
**1. Tile8 Source Canvas Palette Issues**
- **Problem**: The tile8 source canvas (displaying current area graphics) does not show correct colors
- **Impact**: Source tiles appear with incorrect palette, making it difficult to preview how tiles will look
- **Root Cause**: Area graphics not receiving proper palette application
- **Status**: Under investigation - may be related to graphics buffer processing
**2. Palette Button Functionality**
- **Problem**: Palette buttons (0-7) do not properly update the displayed colors
- **Impact**: Cannot switch between different palette groups as intended
- **Expected Behavior**: Clicking palette buttons should change the active palette for tile8 graphics
- **Actual Behavior**: Button clicks do not trigger palette updates correctly
- **Status**: Needs implementation of proper palette switching logic
**3. Color Alignment Between Canvases**
- **Problem**: Colors in tile8 source canvas don't match tile16 editor canvas
- **Impact**: Inconsistent visual feedback during tile editing
- **Related To**: Issues #1 and #2 above
- **Status**: Blocked by palette button functionality
### Current Status Summary
| Component | Status | Notes |
|-----------|--------|-------|
| Crash Prevention | Complete | No SIGBUS errors |
| Three-Column Layout | Complete | Fully functional |
| Zoom Controls | Complete | All canvases working |
| Tile16 Editor Palette | Complete | Shows correct colors |
| Tile8 Source Palette | Warning: In Progress | Incorrect colors displayed |
| Palette Button Updates | Warning: In Progress | Not updating palettes |
| Sheet-Aware Logic | Warning: Partial | Foundation in place, needs fixes |
| Overall Color System | Warning: In Progress | Ongoing development |
### Future Enhancements
1. **Zoom Presets**: Add preset buttons (1x, 2x, 4x) for quick zoom levels
2. **Zoom Sync**: Option to sync zoom levels across related canvases
3. **Canvas Layout Persistence**: Save user's preferred column widths and zoom levels
4. **Keyboard Shortcuts**: Add +/- keys for zoom control
5. **Mouse Wheel Zoom**: Ctrl+Wheel to zoom canvases
6. **Performance Optimization**: Cache palette calculations for frequently used combinations
7. **Extended Debug Tools**: Add pixel-level color comparison tools
8. **Palette Preview**: Real-time preview of palette changes before applying
9. **Batch Operations**: Apply palette changes to multiple tiles simultaneously
## Maintenance Notes
1. **Palette Structure Changes**: Update `GetActualPaletteSlot()` if overworld palette structure changes
2. **Sheet Detection**: Verify `GetSheetIndexForTile8()` logic if graphics organization changes
3. **ProcessGraphicsBuffer**: Monitor for changes in pixel data offset logic
4. **Static Zoom Variables**: User preferences preserved across sessions
---
## Next Steps
### Immediate Priorities
1. **Fix Tile8 Source Canvas Palette Application**
- Investigate graphics buffer processing for area graphics
- Ensure consistent palette application across all graphics sources
- Test with different area graphics combinations
2. **Implement Palette Button Update Logic**
- Add proper event handling for palette button clicks
- Trigger palette refresh for tile8 source canvas
- Update visual feedback to show active palette
3. **Verify Color Consistency**
- Ensure tile8 source colors match tile16 editor
- Test sheet-specific palette regions
- Validate color mapping for all graphics sheets
### Investigation Areas

### Mode 7 Tileset Conversion
Mode 7 graphics live at PC `0x0C4000` as 0x4000 bytes of tiled 8×8 pixel data.
Yaze mirrors ZScream’s tiled-to-linear conversion so SDL can consume it:
```cpp
std::array<uint8_t, 0x4000> mode7_raw = rom_->ReadRange(kMode7Tiles, 0x4000);
int pos = 0;
for (int sy = 0; sy < 16 * 1024; sy += 1024) {
for (int sx = 0; sx < 16 * 8; sx += 8) {
for (int y = 0; y < 8 * 128; y += 128) {
for (int x = 0; x < 8; ++x) {
tileset_[x + sx + y + sy] = mode7_raw[pos++];
}
}
}
}
```
The result is a contiguous 128×128 tileset used by both Light and Dark world
maps.
### Interleaved Tilemap Layout
The 64×64 tilemap (4 096 bytes) is interleaved across four 0x400-byte banks
plus a Dark World override. Copying logic mirrors the original IDK/Zarby docs:
```cpp
auto load_quadrant = [&](uint8_t* dest, const uint8_t* left,
const uint8_t* right) {
for (int count = 0, col = 0; count < 0x800; ++count, ++col) {
*dest++ = (col < 32 ? left : right)[count & 0x3FF];
if (col == 63) col = -1; // wrap every 64 tiles
}
};
load_quadrant(lw_map_, p1, p2); // top half
load_quadrant(lw_map_ + 0x800, p3, p4); // bottom half
```
The Dark World map reuses Light World data except for the final quadrant stored
at `+0x1000`.
### Palette Addresses
- Light World palette: `0x055B27` (128 colors)
- Dark World palette: `0x055C27` (128 colors)
- Conversion uses the shared helper discussed in [G3-palete-system-overview.md](G3-palete-system-overview.md).
### Custom Map Import/Export
The editor ships binary import/export to accelerate iteration:
```cpp
absl::Status OverworldMap::LoadCustomMap(std::string_view path);
absl::Status OverworldMap::SaveCustomMap(std::string_view path, bool dark_world);
```
- Load expects a raw 4 096-byte tilemap; it replaces the active Light/Dark world
buffer and triggers a redraw.
- Save writes either the Light World tilemap or the Dark World override,
allowing collaboration with external tooling.
### Current Status
✅ **ZSCustomOverworld v2/v3 Support**: Fully implemented and tested
✅ **Vanilla ROM Support**: Complete compatibility maintained
✅ **Overlay System**: Both vanilla and custom overlays supported
✅ **Map Properties System**: Integrated with UI components

## Multimodal Vision Workflow
### Step 1: Capture Canvas Screenshot
```bash
# From CLI
z3ed agent vision --capture-canvas "Overworld Canvas" \
--prompt "Analyze this overworld map" \
--rom zelda3.sfc
# From agent workflow
z3ed agent run --prompt "Analyze map 0 and suggest improvements" \
--rom zelda3.sfc --sandbox
```
### Step 2: AI Analyzes Screenshot
Gemini Vision API receives:
- Screenshot of canvas (PNG/JPEG)
- User prompt
- Context (map index, visible region)
AI returns:
```json
{
"analysis": {
"observations": [
"Grass tiles dominate the visible area",
"Tree tiles are sparse and unnatural",
"Water tiles at (15,15) have incorrect palette colors",
"Path from (5,5) to (25,5) is broken"
],
"composition_score": 6.5,
"issues": [
{
"type": "sparse_trees",
"severity": "medium",
"location": {"x": 10, "y": 10},
"suggestion": "Add more tree tiles for forest theme"
}
]
}
}
```
### Step 3: Generate Edit Plan
AI creates actionable plan:
```json
{
"plan": [
{
"tool": "overworld-set-tiles-batch",
"parameters": {
"map": 0,
"tiles": [
{"x": 10, "y": 10, "tile_id": 66},
{"x": 11, "y": 10, "tile_id": 66},
{"x": 12, "y": 10, "tile_id": 66}
]
},
"reason": "Create denser forest area"
}
]
}
```
### Step 4: Execute Plan (Sandbox)
```bash
# z3ed executes plan in sandbox
z3ed agent run --plan plan.json --rom zelda3.sfc --sandbox
```
### Step 5: Human Review
```bash
# View proposed changes
z3ed agent diff --proposal-id abc123
# Accept or reject
z3ed agent accept --proposal-id abc123
# or
z3ed agent reject --proposal-id abc123
```
---
## Example Workflows

---
## Best Practices for AI Agents
### 1. Always Analyze Before Editing
```bash
# GOOD: Check current state first
z3ed agent run --prompt "Analyze map 0 then suggest improvements" --rom zelda3.sfc --sandbox
# BAD: Blindly paint without context
z3ed agent run --prompt "Paint trees everywhere" --rom zelda3.sfc --sandbox
```
### 2. Use Batch Operations
```bash
# GOOD: Single batch operation
overworld-set-tiles-batch (50 tiles)
# BAD: 50 individual operations
overworld-set-tile (×50)
```
### 3. Provide Clear Reasoning
```json
{
"tool": "overworld-set-tile",
"parameters": {"x": 10, "y": 10, "tile_id": 66},
"reason": "Creating forest theme - tree tile at center"
}
```
### 4. Respect Tile Boundaries
Large maps (0x00-0x09, 0x80-0x89) are 512×512 pixels = 32×32 tiles.
Don't paint beyond `(31, 31)` for these maps.
### 5. Check Visibility
```json
{
"step": 1,
"tool": "overworld-get-visible-region",
"reason": "Ensure tiles are visible before analysis"
}
```
### 6. Create Reversible Edits
Always generate proposals that can be rejected:
```bash
z3ed agent run --prompt "..." --rom zelda3.sfc --sandbox # Creates proposal
z3ed agent reject --proposal-id abc123 # Can undo
```
---
## Error Handling
### "Tile ID out of range"
- **Cause**: Invalid tile ID (>4095 for Tile16)
- **Fix**: Validate tile IDs before `set-tile`
### "Coordinates out of bounds"
- **Cause**: Painting beyond map boundaries
- **Fix**: Check map dimensions (typically 32×32 tiles)
### "Proposal rejected"
- **Cause**: Human reviewer rejected changes
- **Fix**: Analyze feedback, adjust plan, try again
### "ROM file locked"
- **Cause**: ROM file open in another process
- **Fix**: Close other instances of YAZE
---
## Testing AI-Generated Edits
### Manual Testing
```bash
# Generate proposal
z3ed agent run --prompt "..." --rom zelda3.sfc --sandbox
# Review in YAZE GUI
yaze zelda3.sfc
# Open Debug → Agent Chat → Proposals
# Review proposal, accept/reject
```
### Automated Testing
```bash
# GUI automation test
z3ed agent test replay overworld_ai_edit.jsonl --rom zelda3.sfc --grpc localhost:50051
# Validate tile placement
z3ed agent test assert --tile-at 10,10 --expected-tile 66 --rom zelda3.sfc
```
---
## Advanced Techniques
### Technique 1: Pattern Recognition
Use multimodal vision to detect patterns:
```bash
z3ed agent vision --capture-canvas "Overworld Canvas" \
--prompt "Identify repeated tile patterns in this map" \
--rom zelda3.sfc
```
AI detects:
- Forest clusters
- Water bodies
- Paths and roads
- Building layouts
### Technique 2: Style Transfer
```bash
z3ed agent run --prompt "Make this map look like Kakariko Village from the dark world" \
--rom zelda3.sfc --sandbox
```
AI:
1. Analyzes Kakariko Village (map 0x18)
2. Extracts tile palette and patterns
3. Applies similar patterns to target map
### Technique 3: Procedural Generation
```bash
z3ed agent run --prompt "Generate a random forest area at 10,10 with natural-looking tree placement" \
--rom zelda3.sfc --sandbox
```
AI uses procedural algorithms:
- Perlin noise for natural randomness
- Clustering for realistic tree placement
- Edge smoothing for organic boundaries
---
## Integration with GUI Automation
### Record Human Edits
```bash
# Record editing session
z3ed agent test record --suite overworld_forest.jsonl --rom zelda3.sfc
```
### Replay for AI Training
```bash
# Replay recorded session
z3ed agent test replay overworld_forest.jsonl --rom zelda3.sfc
# AI learns from human edits
z3ed agent learn --from-recording overworld_forest.jsonl
```
### Validate AI Edits
```bash
# AI generates edits
z3ed agent run --prompt "..." --rom zelda3.sfc --sandbox
# GUI automation validates
z3ed agent test verify --proposal-id abc123 --suite validation_tests.jsonl
```
---
## Collaboration Features
### Network Collaboration
```bash
# Connect to yaze-server
z3ed net connect ws://localhost:8765
# Join session
z3ed net join ABC123 --username "ai-agent"
# AI agent edits, humans review in real-time
z3ed agent run --prompt "..." --rom zelda3.sfc --sandbox
# Proposal synced to all participants
```
### Proposal Voting
```bash
# Submit proposal to session
z3ed proposal submit --proposal-id abc123 --session ABC123
# Wait for votes
z3ed proposal wait --proposal-id abc123
# Check result
z3ed proposal status --proposal-id abc123
# Output: approved (3/3 votes)
```
---
## Troubleshooting
### Agent Not Responding
```bash
# Check AI provider
z3ed agent ping
# Test simple query
z3ed agent simple-chat "Hello" --rom zelda3.sfc
```
### Tools Not Available
```bash
# Verify z3ed build
z3ed agent describe --resource overworld
# Should show:
# - overworld-get-tile
# - overworld-set-tile
# - overworld-analyze-region
```
### gRPC Connection Failed
```bash
# Check YAZE is running with gRPC
z3ed agent test ping --grpc localhost:50051
# Start YAZE with gRPC enabled
yaze --enable-grpc zelda3.sfc
```

# Canvas System Overview
## Canvas Architecture
- **Canvas States**: track `canvas`, `content`, and `draw` rectangles independently; expose size/scale through `CanvasState` inspection panel
- **Layer Stack**: background ➝ bitmaps ➝ entity overlays ➝ selection/tooltip layers
- **Interaction Modes**: Tile Paint, Tile Select, Rectangle Select, Entity Manipulation, Palette Editing, Diagnostics
- **Context Menu**: persistent menu with material icon sections (Mode, View, Info, Bitmap, Palette, BPP, Performance, Layout, Custom)
## Core API Patterns
- Modern usage: `Begin/End` (auto grid/overlay, persistent context menu)
- Legacy helpers still available (`DrawBackground`, `DrawGrid`, `DrawSelectRect`, etc.)
- Unified state snapshot: `CanvasState` exposes geometry, zoom, scroll
- Interaction handler manages mode-specific tools (tile brush, select rect, entity gizmo)
## Context Menu Sections
- **Mode Selector**: switch modes with icons (Brush, Select, Rect, Bitmap, Palette, BPP, Perf)
- **View & Grid**: reset/zoom, toggle grid/labels, advanced/scaling dialogs
- **Canvas Info**: real-time canvas/content size, scale, scroll, mouse position
- **Bitmap/Palette/BPP**: format conversion, palette analysis, BPP workflows with persistent modals
- **Performance**: profiler metrics, dashboard, usage report
- **Layout**: draggable toggle, auto resize, grid step
- **Custom Actions**: consumer-provided menu items
## Interaction Modes & Capabilities
- **Tile Painting**: tile16 painter, brush size, finish stroke callbacks
- Operations: finish_paint, reset_view, zoom, grid, scaling
- **Tile Selection**: multi-select rectangle, copy/paste selection
- Operations: select_all, clear_selection, reset_view, zoom, grid, scaling
- **Rectangle Selection**: drag-select area, clear selection
- Operations: clear_selection, reset_view, zoom, grid, scaling
- **Bitmap Editing**: format conversion, bitmap manipulation
- Operations: bitmap_convert, palette_edit, bpp_analysis, reset_view, zoom, grid, scaling
- **Palette Editing**: inline palette editor, ROM palette picker, color analysis
- Operations: palette_edit, palette_analysis, reset_palette, reset_view, zoom, grid, scaling
- **BPP Conversion**: format analysis, conversion workflows
- Operations: bpp_analysis, bpp_conversion, bitmap_convert, reset_view, zoom, grid, scaling
- **Performance Mode**: diagnostics, texture queue, performance overlays
- Operations: performance, usage_report, copy_metrics, reset_view, zoom, grid, scaling
## Debug & Diagnostics
- Persistent modals (`View→Advanced`, `View→Scaling`, `Palette`, `BPP`) stay open until closed
- Texture inspector shows current bitmap, VRAM sheet, palette group, usage stats
- State overlay: canvas size, content size, global scale, scroll, highlight entity
- Performance HUD: operation counts, timing graphs, usage recommendations
## Automation API
- CanvasAutomationAPI: tile operations (`SetTileAt`, `SelectRect`), view control (`ScrollToTile`, `SetZoom`), entity manipulation hooks
- Exposed through CLI (`z3ed`) and gRPC service, matching UI modes
## Integration Steps for Editors
1. Construct `Canvas`, set renderer (optional) and ID
2. Call `InitializePaletteEditor` and `SetUsageMode`
3. Configure available modes: `SetAvailableModes({kTilePainting, kTileSelecting})`
4. Register mode callbacks (tile paint finish, selection clear, etc.)
5. During frame: `canvas.Begin(size)` → draw bitmaps/entities → `canvas.End()`
6. Provide custom menu items via `AddMenuItem`/`AddMenuItem(item, usage)`
7. Use `GetConfig()`/`GetSelection()` for state; respond to context menu commands via callback lambda in `Render`
## Migration Checklist
- Replace direct `DrawContextMenu` logic with new render callback signature
- Move palette/BPP helpers into `canvas/` module; update includes
- Ensure persistent modals wired (advanced/scaling/palette/bpp/perf)
- Update usage tracker integrations to record mode switches
- Validate overworld/tile16/dungeon editors in tile paint, select, entity modes
## Testing Notes
- Manual regression: overworld paint/select, tile16 painter, dungeon entity drag
- Verify context menu persists and modals remain until closed
- Ensure palette/BPP modals populate with correct bitmap/palette data
- Automation: run CanvasAutomation API tests/end-to-end scripts for overworld edits

# SDL2 to SDL3 Migration and Rendering Abstraction Plan
## 1. Introduction
This document outlines a strategic plan to refactor the rendering architecture of the `yaze` application. The primary goals are:
1. **Decouple the application from the SDL2 rendering API.**
2. **Create a clear and straightforward path for migrating to SDL3.**
3. **Enable support for multiple rendering backends** (e.g., OpenGL, Metal, DirectX) to improve cross-platform performance and leverage modern graphics APIs.
## 2. Current State Analysis
The current architecture exhibits tight coupling with the SDL2 rendering API.
- **Direct Dependency:** Components like `gfx::Bitmap`, `gfx::Arena`, and `gfx::AtlasRenderer` directly accept or call functions using an `SDL_Renderer*`.
- **Singleton Pattern:** The `core::Renderer` singleton in `src/app/core/window.h` provides global access to the `SDL_Renderer`, making it difficult to manage, replace, or mock.
- **Dual Rendering Pipelines:** The main application (`yaze.cc`, `app_delegate.mm`) and the standalone emulator (`app/emu/emu.cc`) both perform their own separate, direct SDL initialization and rendering loops. This code duplication makes maintenance and migration efforts more complex.
This tight coupling makes it brittle, difficult to maintain, and nearly impossible to adapt to newer rendering APIs like SDL3 or other backends without a major, project-wide rewrite.
## 3. Proposed Architecture: The `Renderer` Abstraction
The core of this plan is to introduce a `Renderer` interface (an abstract base class) that defines a set of rendering primitives. The application will be refactored to program against this interface, not a concrete SDL2 implementation.
### 3.1. The `IRenderer` Interface
A new interface, `IRenderer`, will be created. It will define the contract for all rendering operations.
**File:** `src/app/gfx/irenderer.h`
```cpp
#pragma once
#include <SDL.h> // For SDL_Rect, SDL_Color, etc.
#include <memory>
#include <vector>
#include "app/gfx/bitmap.h"
namespace yaze {
namespace gfx {
// Forward declarations
class Bitmap;
// A handle to a texture, abstracting away the underlying implementation
using TextureHandle = void*;
class IRenderer {
public:
virtual ~IRenderer() = default;
// --- Initialization and Lifecycle ---
virtual bool Initialize(SDL_Window* window) = 0;
virtual void Shutdown() = 0;
// --- Texture Management ---
virtual TextureHandle CreateTexture(int width, int height) = 0;
virtual void UpdateTexture(TextureHandle texture, const Bitmap& bitmap) = 0;
virtual void DestroyTexture(TextureHandle texture) = 0;
// --- Rendering Primitives ---
virtual void Clear() = 0;
virtual void Present() = 0;
virtual void RenderCopy(TextureHandle texture, const SDL_Rect* srcrect, const SDL_Rect* dstrect) = 0;
virtual void SetRenderTarget(TextureHandle texture) = 0;
virtual void SetDrawColor(SDL_Color color) = 0;
// --- Backend-specific Access ---
// Provides an escape hatch for libraries like ImGui that need the concrete renderer.
virtual void* GetBackendRenderer() = 0;
};
} // namespace gfx
} // namespace yaze
```
### 3.2. The `SDL2Renderer` Implementation
A concrete class, `SDL2Renderer`, will be the first implementation of the `IRenderer` interface. It will encapsulate all the existing SDL2-specific rendering logic.
**File:** `src/app/gfx/sdl2_renderer.h` & `src/app/gfx/sdl2_renderer.cc`
```cpp
// sdl2_renderer.h
#include "app/gfx/irenderer.h"
#include "util/sdl_deleter.h"
namespace yaze {
namespace gfx {
class SDL2Renderer : public IRenderer {
public:
SDL2Renderer();
~SDL2Renderer() override;
bool Initialize(SDL_Window* window) override;
void Shutdown() override;
TextureHandle CreateTexture(int width, int height) override;
void UpdateTexture(TextureHandle texture, const Bitmap& bitmap) override;
void DestroyTexture(TextureHandle texture) override;
void Clear() override;
void Present() override;
void RenderCopy(TextureHandle texture, const SDL_Rect* srcrect, const SDL_Rect* dstrect) override;
void SetRenderTarget(TextureHandle texture) override;
void SetDrawColor(SDL_Color color) override;
void* GetBackendRenderer() override { return renderer_.get(); }
private:
std::unique_ptr<SDL_Renderer, util::SDL_Deleter> renderer_;
};
} // namespace gfx
} // namespace yaze
```
## 4. Migration Plan
The migration will be executed in phases to ensure stability and minimize disruption.
### Phase 1: Implement the Abstraction Layer
1. **Create `IRenderer` and `SDL2Renderer`:** Implement the interface and concrete class as defined above.
2. **Refactor `core::Renderer` Singleton:** The existing `core::Renderer` singleton will be deprecated and removed. A new central mechanism (e.g., a service locator or passing the `IRenderer` instance) will provide access to the active renderer.
3. **Update Application Entry Points:**
* In `app/core/controller.cc` (for the main editor) and `app/emu/emu.cc` (for the emulator), instantiate `SDL2Renderer` during initialization. The `Controller` will own the `unique_ptr<IRenderer>`.
* This immediately unifies the rendering pipeline initialization for both application modes.
4. **Refactor `gfx` Library:**
* **`gfx::Bitmap`:** Modify `CreateTexture` and `UpdateTexture` to accept an `IRenderer*` instead of an `SDL_Renderer*`. The `SDL_Texture*` will be replaced with the abstract `TextureHandle`.
* **`gfx::Arena`:** The `AllocateTexture` method will now call `renderer->CreateTexture()`. The internal pools will store `TextureHandle`s.
* **`gfx::AtlasRenderer`:** The `Initialize` method will take an `IRenderer*`. All calls to `SDL_RenderCopy`, `SDL_SetRenderTarget`, etc., will be replaced with calls to the corresponding methods on the `IRenderer` interface.
5. **Update ImGui Integration:**
* The ImGui backend requires the concrete `SDL_Renderer*`. The `GetBackendRenderer()` method on the interface provides a type-erased `void*` for this purpose.
* The ImGui initialization code will be modified as follows:
```cpp
// Before
ImGui_ImplSDLRenderer2_Init(sdl_renderer_ptr);
// After
auto backend_renderer = renderer->GetBackendRenderer();
ImGui_ImplSDLRenderer2_Init(static_cast<SDL_Renderer*>(backend_renderer));
```
### Phase 2: Migrate to SDL3
With the abstraction layer in place, migrating to SDL3 becomes significantly simpler.
1. **Create `SDL3Renderer`:** A new class, `SDL3Renderer`, will be created that implements the `IRenderer` interface using SDL3's rendering functions.
* This class will handle the differences in the SDL3 API (e.g., `SDL_CreateRendererWithProperties`, float-based rendering functions, etc.) internally.
* The `TextureHandle` will now correspond to an `SDL_Texture*` from SDL3.
2. **Update Build System:** The CMake files will be updated to link against SDL3 instead of SDL2.
3. **Switch Implementation:** The application entry points (`controller.cc`, `emu.cc`) will be changed to instantiate `SDL3Renderer` instead of `SDL2Renderer`.
The rest of the application, which only knows about the `IRenderer` interface, will require **no changes**.
### Phase 3: Support for Multiple Rendering Backends
The `IRenderer` interface makes adding new backends a modular task.
1. **Implement New Backends:** Create new classes like `OpenGLRenderer`, `MetalRenderer`, or `VulkanRenderer`. Each will implement the `IRenderer` interface using the corresponding graphics API.
2. **Backend Selection:** Implement a factory function or a strategy in the main controller to select and create the desired renderer at startup, based on platform, user configuration, or command-line flags.
3. **ImGui Backend Alignment:** When a specific backend is chosen for `yaze`, the corresponding ImGui backend implementation must also be used (e.g., `ImGui_ImplOpenGL3_Init`, `ImGui_ImplMetal_Init`). The `GetBackendRenderer()` method will provide the necessary context (e.g., `ID3D11Device*`, `MTLDevice*`) for each implementation.
## 5. Conclusion
This plan transforms the rendering system from a tightly coupled, monolithic design into a flexible, modular, and future-proof architecture.
**Benefits:**
- **Maintainability:** Rendering logic is centralized and isolated, making it easier to debug and maintain.
- **Extensibility:** Adding support for new rendering APIs (like SDL3, Vulkan, Metal) becomes a matter of implementing a new interface, not refactoring the entire application.
- **Testability:** The rendering interface can be mocked, allowing for unit testing of graphics components without a live rendering context.
- **Future-Proofing:** The application is no longer tied to a specific version of SDL, ensuring a smooth transition to future graphics technologies.

# SNES Palette System Overview
## Understanding SNES Color and Palette Organization
### Core Concepts
#### 1. SNES Color Format (15-bit BGR555)
- **Storage**: 2 bytes per color (16 bits total, 15 bits used)
- **Format**: `0BBB BBGG GGGR RRRR`
- Bits 0-4: Red (5 bits, 0-31)
- Bits 5-9: Green (5 bits, 0-31)
- Bits 10-14: Blue (5 bits, 0-31)
- Bit 15: Unused (always 0)
- **Range**: Each channel has 32 levels (0-31)
- **Total Colors**: 32,768 possible colors (2^15)
#### 2. Palette Groups in Zelda 3
Zelda 3 organizes palettes into logical groups for different game areas and entities:
```cpp
struct PaletteGroupMap {
PaletteGroup overworld_main; // Main overworld graphics (35 colors each)
PaletteGroup overworld_aux; // Auxiliary overworld (21 colors each)
PaletteGroup overworld_animated; // Animated colors (7 colors each)
PaletteGroup hud; // HUD graphics (32 colors each)
PaletteGroup global_sprites; // Sprite palettes (60 colors each)
PaletteGroup armors; // Armor colors (15 colors each)
PaletteGroup swords; // Sword colors (3 colors each)
PaletteGroup shields; // Shield colors (4 colors each)
PaletteGroup sprites_aux1; // Auxiliary sprite palette 1 (7 colors each)
PaletteGroup sprites_aux2; // Auxiliary sprite palette 2 (7 colors each)
PaletteGroup sprites_aux3; // Auxiliary sprite palette 3 (7 colors each)
PaletteGroup dungeon_main; // Dungeon palettes (90 colors each)
PaletteGroup grass; // Grass colors (special handling)
PaletteGroup object_3d; // 3D object palettes (8 colors each)
PaletteGroup overworld_mini_map; // Mini-map palettes (128 colors each)
};
```
#### 3. Color Representations in Code
- **SNES 15-bit (`uint16_t`)**: On-disk format `0bbbbbgggggrrrrr`; store raw ROM
words or write back with `ConvertRgbToSnes`.
- **`gfx::snes_color` struct**: Expands each channel to 0-255 for arithmetic
without floating point; use in converters and palette math.
- **`gfx::SnesColor` class**: High-level wrapper retaining the original SNES
value, a `snes_color`, and an ImVec4. Its `rgb()` accessor purposely returns
0-255 components—run the helper converters (e.g., `ConvertSnesColorToImVec4`)
before handing colors to ImGui widgets that expect 0.0-1.0 floats.
### Dungeon Palette System
#### Structure
- **20 dungeon palettes** in the `dungeon_main` group
- **90 colors per palette** (full SNES palette for BG layers)
- **ROM Location**: `kDungeonMainPalettes` (check `snes_palette.cc` for exact address)
#### Usage
```cpp
// Loading a dungeon palette
auto& dungeon_pal_group = rom->palette_group().dungeon_main;
int num_palettes = dungeon_pal_group.size(); // Should be 20
int palette_id = room.palette; // Room's palette ID (0-19)
// IMPORTANT: Use operator[] not palette() method!
auto palette = dungeon_pal_group[palette_id]; // Returns reference
// NOT: auto palette = dungeon_pal_group.palette(palette_id); // Returns copy!
```
#### Color Distribution (90 colors)
The 90 colors are typically distributed as:
- **BG1 Palette** (Background Layer 1): First 8-16 subpalettes
- **BG2 Palette** (Background Layer 2): Next 8-16 subpalettes
- **Sprite Palettes**: Remaining colors (handled separately)
Each "subpalette" is 16 colors (one SNES palette unit).
### Overworld Palette System
#### Structure
- **Main Overworld**: 35 colors per palette
- **Auxiliary**: 21 colors per palette
- **Animated**: 7 colors per palette (for water, lava effects)
#### 3BPP Graphics and Left/Right Palettes
Overworld graphics use 3BPP (3 bits per pixel) format:
- **8 colors per tile** (2^3 = 8)
- **Left Side**: Uses palette 0-7
- **Right Side**: Uses palette 8-15
When decompressing 3BPP graphics:
```cpp
// Palette assignment for 3BPP overworld tiles
if (tile_position < half_screen_width) {
// Left side of screen
tile_palette_offset = 0; // Use colors 0-7
} else {
// Right side of screen
tile_palette_offset = 8; // Use colors 8-15
}
```
### Common Issues and Solutions
#### Issue 1: Empty Palette
**Symptom**: "Palette size: 0 colors"
**Cause**: Using `palette()` method instead of `operator[]`
**Solution**:
```cpp
// WRONG:
auto palette = group.palette(id); // Returns copy, may be empty
// CORRECT:
auto palette = group[id]; // Returns reference
```
#### Issue 2: Bitmap Corruption
**Symptom**: Graphics render only in top portion of image
**Cause**: Wrong depth parameter in `CreateAndRenderBitmap`
**Solution**:
```cpp
// WRONG:
CreateAndRenderBitmap(0x200, 0x200, 0x200, data, bitmap, palette);
// depth ^^^^ should be 8!
// CORRECT:
CreateAndRenderBitmap(0x200, 0x200, 8, data, bitmap, palette);
// width, height, depth=8 bits
```
### Transparency and Conversion Best Practices
- Preserve ROM palette words exactly as read; hardware enforces transparency on
index 0 so we no longer call `set_transparent(true)` while loading.
- Apply transparency only at render time via `SetPaletteWithTransparent()` for
3BPP sub-palettes or `SetPalette()` for full 256-color assets.
- `SnesColor::rgb()` yields components in 0-255 space; convert to ImGui’s
expected 0.0-1.0 floats with the helper functions instead of manual divides.
- Use the provided conversion helpers (`ConvertSnesToRgb`, `ImVec4ToSnesColor`,
`SnesTo8bppColor`) to prevent rounding mistakes and alpha bugs.
```cpp
ImVec4 rgb_255 = snes_color.rgb();
ImVec4 display = ConvertSnesColorToImVec4(snes_color);
ImGui::ColorButton("color", display);
```
#### Issue 3: ROM Not Loaded in Preview
**Symptom**: "ROM not loaded" error in emulator preview
**Cause**: Initializing before ROM is set
**Solution**:
```cpp
// Initialize emulator preview AFTER ROM is loaded and set
void Load() {
// ... load ROM data ...
// ... set up other components ...
// NOW initialize emulator preview with loaded ROM
object_emulator_preview_.Initialize(rom_);
}
```
### Palette Editor Integration
#### Key Functions for UI
```cpp
// Reading a color from ROM
absl::StatusOr<uint16_t> ReadColorFromRom(uint32_t address, const uint8_t* rom);
// Converting SNES color to RGB
SnesColor color(snes_value); // snes_value is uint16_t
uint8_t r = color.red(); // 0-255 (converted from 0-31)
uint8_t g = color.green(); // 0-255
uint8_t b = color.blue(); // 0-255
// Writing color back to ROM
uint16_t snes_value = color.snes(); // Get 15-bit BGR555 value
rom->WriteByte(address, snes_value & 0xFF); // Low byte
rom->WriteByte(address + 1, (snes_value >> 8) & 0xFF); // High byte
```
#### Palette Widget Requirements
1. **Display**: Show colors in organized grids (16 colors per row for SNES standard)
2. **Selection**: Allow clicking to select a color
3. **Editing**: Provide RGB sliders (0-255) or color picker
4. **Conversion**: Auto-convert RGB (0-255) ↔ SNES (0-31) values
5. **Preview**: Show before/after comparison
6. **Save**: Write modified palette back to ROM
#### Palette UI Helpers
- `InlinePaletteSelector` renders a lightweight selection strip (no editing)
ideal for 8- or 16-color sub-palettes.
- `InlinePaletteEditor` supplies the full editing experience with ImGui color
pickers, context menus, and optional live preview toggles.
- `PopupPaletteEditor` fits in context menus or modals; it caps at 64 colors to
keep popups manageable.
- Legacy helpers such as `DisplayPalette()` remain for backward compatibility
but inherit the 32-color limit—prefer the new helpers for new UI.
-### Metadata-Driven Palette Application
`gfx::BitmapMetadata` tracks the source BPP, palette format, type string, and
expected color count. Set it immediately after creating a bitmap so later code
can make the right choice automatically:
```cpp
bitmap.metadata() = BitmapMetadata{/*source_bpp=*/3,
/*palette_format=*/1, // 0=full, 1=sub-palette
/*source_type=*/"graphics_sheet",
/*palette_colors=*/8};
bitmap.ApplyPaletteByMetadata(palette);
```
- `palette_format == 0` routes to `SetPalette()` and preserves every color
(Mode 7, HUD assets, etc.).
- `palette_format == 1` routes to `SetPaletteWithTransparent()` and injects the
transparent color 0 for 3BPP workflows.
- Validation hooks help catch mismatched palette sizes before they hit SDL.
### Graphics Manager Integration
#### Sheet Palette Assignment
```cpp
// Assigning palette to graphics sheet
if (sheet_id > 115) {
// Sprite sheets use sprite palette
graphics_sheet.SetPaletteWithTransparent(
rom.palette_group().global_sprites[0], 0);
} else {
// Dungeon sheets use dungeon palette
graphics_sheet.SetPaletteWithTransparent(
rom.palette_group().dungeon_main[0], 0);
}
```
### Texture Synchronization and Regression Notes
- Call `bitmap.UpdateSurfacePixels()` after mutating `bitmap.mutable_data()` to
copy rendered bytes into the SDL surface before queuing texture creation or
updates.
- `Bitmap::ApplyStoredPalette()` now rebuilds an `SDL_Color` array sized to the
actual palette instead of forcing 256 entries—this fixes regressions where
8- or 16-color palettes were padded with opaque black.
- When updating SDL palette data yourself, mirror that pattern:
```cpp
std::vector<SDL_Color> colors(palette.size());
for (size_t i = 0; i < palette.size(); ++i) {
const auto& c = palette[i];
const ImVec4 rgb = c.rgb(); // 0-255 components
colors[i] = SDL_Color{static_cast<Uint8>(rgb.x),
static_cast<Uint8>(rgb.y),
static_cast<Uint8>(rgb.z),
c.is_transparent() ? 0 : 255};
}
SDL_SetPaletteColors(surface->format->palette, colors.data(), 0,
static_cast<int>(colors.size()));
```
### Best Practices
1. **Always use `operator[]` for palette access** - returns reference, not copy
2. **Validate palette IDs** before accessing:
```cpp
if (palette_id >= 0 && palette_id < group.size()) {
auto palette = group[palette_id];
}
```
3. **Use correct depth parameter** when creating bitmaps (usually 8 for indexed color)
4. **Initialize ROM-dependent components** only after ROM is fully loaded
5. **Cache palettes** when repeatedly accessing the same palette
6. **Update textures** after changing palettes (textures don't auto-update)
### User Workflow Tips
- Choose the widget that matches the task: selectors for choosing colors,
editors for full control, popups for contextual tweaks.
- The live preview toggle trades responsiveness for performance; disable it
while batch-editing large (64+ color) palettes.
- Right-click any swatch in the editor to copy the color as SNES hex, RGB
tuples, or HTML hex—useful when coordinating with external art tools.
- Remember hardware rules: palette index 0 is always transparent and will not
display even if the stored value is non-zero.
- Keep ROM backups when performing large palette sweeps; palette groups are
shared across screens so a change can have multiple downstream effects.
### ROM Addresses (for reference)
```cpp
// From snes_palette.cc
constexpr uint32_t kOverworldPaletteMain = 0xDE6C8;
constexpr uint32_t kOverworldPaletteAux = 0xDE86C;
constexpr uint32_t kOverworldPaletteAnimated = 0xDE604;
constexpr uint32_t kHudPalettes = 0xDD218;
constexpr uint32_t kGlobalSpritesLW = 0xDD308;
constexpr uint32_t kArmorPalettes = 0xDD630;
constexpr uint32_t kSwordPalettes = 0xDD630;
constexpr uint32_t kShieldPalettes = 0xDD648;
constexpr uint32_t kSpritesPalettesAux1 = 0xDD39E;
constexpr uint32_t kSpritesPalettesAux2 = 0xDD446;
constexpr uint32_t kSpritesPalettesAux3 = 0xDD4E0;
constexpr uint32_t kDungeonMainPalettes = 0xDD734;
constexpr uint32_t kHardcodedGrassLW = 0x5FEA9;
constexpr uint32_t kTriforcePalette = 0xF4CD0;
constexpr uint32_t kOverworldMiniMapPalettes = 0x55B27;
```
## Graphics Sheet Palette Application
### Default Palette Assignment
Graphics sheets receive default palettes during ROM loading based on their index:
```cpp
// In LoadAllGraphicsData() - rom.cc
if (i < 113) {
// Sheets 0-112: Overworld/Dungeon graphics
graphics_sheets[i].SetPalette(rom.palette_group().dungeon_main[0]);
} else if (i < 128) {
// Sheets 113-127: Sprite graphics
graphics_sheets[i].SetPalette(rom.palette_group().sprites_aux1[0]);
} else {
// Sheets 128-222: Auxiliary/HUD graphics
graphics_sheets[i].SetPalette(rom.palette_group().hud.palette(0));
}
```
This ensures graphics are visible immediately after loading rather than appearing white.
### Palette Update Workflow
When changing a palette in any editor:
1. Apply the palette: `bitmap.SetPalette(new_palette)`
2. Notify Arena: `gfx::Arena::Get().NotifySheetModified(sheet_index)`
3. Changes propagate to all editors automatically
### Common Pitfalls
**Wrong Palette Access**:
```cpp
// WRONG - Returns copy, may be empty
auto palette = group.palette(id);
// CORRECT - Returns reference
auto palette = group[id];
```
**Missing Surface Update**:
```cpp
// WRONG - Only updates vector, not SDL surface
bitmap.mutable_data() = new_data;
// CORRECT - Updates both vector and surface
bitmap.set_data(new_data);
```

# Canvas Coordinate Synchronization and Scroll Fix
**Date**: October 10, 2025
**Issues**:
1. Overworld map highlighting regression after canvas refactoring
2. Overworld canvas scrolling unexpectedly when selecting tiles
3. Vanilla Dark/Special World large map outlines not displaying
**Status**: Fixed
## Problem Summary
After the canvas refactoring (commits f538775954, 60ddf76331), two critical bugs appeared:
1. **Map highlighting broken**: The overworld editor stopped properly highlighting the current map when hovering. The map highlighting only worked during active tile painting, not during normal mouse hover.
2. **Wrong canvas scrolling**: When right-clicking to select tiles (especially on Dark World), the overworld canvas would scroll unexpectedly instead of the tile16 blockset selector.
## Root Cause
The regression had **FIVE** issues:
### Issue 1: Wrong Coordinate System (Line 1041)
**File**: `src/app/editor/overworld/overworld_editor.cc:1041`
**Before (BROKEN)**:
```cpp
const auto mouse_position = ImGui::GetIO().MousePos; // ❌ Screen coordinates!
const auto canvas_zero_point = ow_map_canvas_.zero_point();
int map_x = (mouse_position.x - canvas_zero_point.x) / kOverworldMapSize;
```
**After (FIXED)**:
```cpp
const auto mouse_position = ow_map_canvas_.hover_mouse_pos(); // World coordinates!
int map_x = mouse_position.x / kOverworldMapSize;
```
**Why This Was Wrong**:
- `ImGui::GetIO().MousePos` returns **screen space** coordinates (absolute position on screen)
- The canvas may be scrolled, scaled, or positioned anywhere on screen
- Screen coordinates don't account for canvas scrolling/offset
- `hover_mouse_pos()` returns **canvas/world space** coordinates (relative to canvas content)
### Issue 2: Hover Position Not Updated (Line 416)
**File**: `src/app/gui/canvas.cc:416`
**Before (BROKEN)**:
```cpp
void Canvas::DrawBackground(ImVec2 canvas_size) {
// ... setup code ...
ImGui::InvisibleButton(canvas_id_.c_str(), scaled_size, kMouseFlags);
// ❌ mouse_pos_in_canvas_ only updated in DrawTilePainter() during painting!
if (config_.is_draggable && IsItemHovered()) {
// ... pan handling ...
}
}
```
`mouse_pos_in_canvas_` was only updated inside painting methods:
- `DrawTilePainter()` at line 741
- `DrawSolidTilePainter()` at line 860
- `DrawTileSelector()` at line 929
**After (FIXED)**:
```cpp
void Canvas::DrawBackground(ImVec2 canvas_size) {
// ... setup code ...
ImGui::InvisibleButton(canvas_id_.c_str(), scaled_size, kMouseFlags);
// CRITICAL FIX: Always update hover position when hovering
if (IsItemHovered()) {
const ImGuiIO& io = GetIO();
const ImVec2 origin(canvas_p0_.x + scrolling_.x, canvas_p0_.y + scrolling_.y);
const ImVec2 mouse_pos(io.MousePos.x - origin.x, io.MousePos.y - origin.y);
mouse_pos_in_canvas_ = mouse_pos; // Updated every frame during hover
}
if (config_.is_draggable && IsItemHovered()) {
// ... pan handling ...
}
}
```
## Technical Details
### Coordinate Spaces
yaze has three coordinate spaces:
1. **Screen Space**: Absolute pixel coordinates on the monitor
- `ImGui::GetIO().MousePos` returns this
- Never use this for canvas operations!
2. **Canvas/World Space**: Coordinates relative to canvas content
- Accounts for canvas scrolling and offset
- `Canvas::hover_mouse_pos()` returns this
- Use this for map calculations, entity positioning, etc.
3. **Tile/Grid Space**: Coordinates in tile units (not pixels)
- `Canvas::CanvasToTile()` converts from canvas to grid space
- Used by automation API
### Usage Patterns
**For Hover/Highlighting** (CheckForCurrentMap):
```cpp
auto hover_pos = canvas.hover_mouse_pos(); // Updates continuously
int map_x = hover_pos.x / kOverworldMapSize;
```
**For Active Painting** (DrawOverworldEdits):
```cpp
auto paint_pos = canvas.drawn_tile_position(); // Updates only during drag
int map_x = paint_pos.x / kOverworldMapSize;
```
## Testing
### Visual Testing
**Map Highlighting Test**:
1. Open overworld editor
2. Hover mouse over different maps (without clicking)
3. Verify current map highlights correctly
4. Test with different scale levels (0.25x - 4.0x)
5. Test with scrolled canvas
**Scroll Regression Test**:
1. Open overworld editor
2. Switch to Dark World (or any world)
3. Right-click on overworld canvas to select a tile
4. **Expected**: Tile16 blockset selector scrolls to show the selected tile
5. **Expected**: Overworld canvas does NOT scroll
6. ❌ **Before fix**: Overworld canvas would scroll unexpectedly
### Unit Tests
Created `test/unit/gui/canvas_coordinate_sync_test.cc` with regression tests:
- `HoverMousePos_IndependentFromDrawnPos`: Verifies hover vs paint separation
- `CoordinateSpace_WorldNotScreen`: Ensures world coordinates used
- `MapCalculation_SmallMaps`: Tests 512x512 map boundaries
- `MapCalculation_LargeMaps`: Tests 1024x1024 v3 ASM maps
- `OverworldMapHighlight_UsesHoverNotDrawn`: Critical regression test
- `OverworldMapIndex_From8x8Grid`: Tests all three worlds (Light/Dark/Special)
Run tests:
```bash
./build/bin/yaze_test --unit
```
## Impact Analysis
### Files Changed
1. `src/app/editor/overworld/overworld_editor.cc` (line 1041-1049)
- Changed from screen coordinates to canvas hover coordinates
- Removed incorrect `canvas_zero_point` subtraction
2. `src/app/gui/canvas.cc` (line 414-421)
- Added continuous hover position tracking in `DrawBackground()`
- Now updates `mouse_pos_in_canvas_` every frame when hovering
3. `src/app/editor/overworld/overworld_editor.cc` (line 2344-2360)
- Removed fallback scroll code that scrolled the wrong canvas
- Now only uses `blockset_selector_->ScrollToTile()` which targets the correct canvas
4. `src/app/editor/overworld/overworld_editor.cc` (line 1403-1408)
- Changed from `ImGui::IsItemHovered()` (checks last drawn item)
- To `ow_map_canvas_.IsMouseHovering()` (checks canvas hover state directly)
5. `src/app/editor/overworld/overworld_editor.cc` (line 1133-1151)
- Added world offset subtraction for vanilla large map parent coordinates
- Now properly accounts for Dark World (0x40-0x7F) and Special World (0x80-0x9F)
### Affected Functionality
- **Fixed**: Overworld map highlighting during hover (all worlds, all ROM types)
- **Fixed**: Vanilla Dark World large map highlighting (was drawing off-screen)
- **Fixed**: Vanilla Special World large map highlighting (was drawing off-screen)
- **Fixed**: Overworld canvas no longer scrolls when selecting tiles
- **Fixed**: Tile16 selector properly scrolls to show selected tile (via blockset_selector_)
- **Fixed**: Entity renderer using `hover_mouse_pos()` (already worked correctly)
- **Preserved**: Tile painting using `drawn_tile_position()` (unchanged)
- **Preserved**: Multi-area map support (512x512, 1024x1024)
- **Preserved**: All three worlds (Light 0x00-0x3F, Dark 0x40-0x7F, Special 0x80+)
- **Preserved**: ZSCustomOverworld v3 large maps (already worked correctly)
### Related Code That Works Correctly
These files already use the correct pattern:
- `src/app/editor/overworld/overworld_entity_renderer.cc:68-69` - Uses `hover_mouse_pos()` for entity placement
- `src/app/editor/overworld/overworld_editor.cc:664` - Uses `drawn_tile_position()` for painting
## Multi-Area Map Support
The fix properly handles all area sizes:
### Standard Maps (512x512)
```cpp
int map_x = hover_pos.x / 512; // 0-7 range
int map_y = hover_pos.y / 512; // 0-7 range
int map_index = map_x + map_y * 8; // 0-63 (8x8 grid)
```
### ZSCustomOverworld v3 Large Maps (1024x1024)
```cpp
int map_x = hover_pos.x / 1024; // Large map X
int map_y = hover_pos.y / 1024; // Large map Y
// Parent map calculation handled in lines 1073-1190
```
The existing multi-area logic (lines 1068-1190) remains unchanged and works correctly with the fix.
## Issue 3: Wrong Canvas Being Scrolled (Line 2344-2366)
**File**: `src/app/editor/overworld/overworld_editor.cc:2344`
**Problem**: When selecting tiles with right-click on the overworld canvas, `ScrollBlocksetCanvasToCurrentTile()` was calling `ImGui::SetScrollX/Y()` which scrolls **the current ImGui window**, not a specific canvas.
**Call Stack**:
```
DrawOverworldCanvas() // Overworld canvas is current window
└─ CheckForOverworldEdits() (line 1401)
└─ CheckForSelectRectangle() (line 793)
└─ ScrollBlocksetCanvasToCurrentTile() (line 916)
└─ ImGui::SetScrollX/Y() (lines 2364-2365) // ❌ Scrolls CURRENT window!
```
**Before (BROKEN)**:
```cpp
void OverworldEditor::ScrollBlocksetCanvasToCurrentTile() {
if (blockset_selector_) {
blockset_selector_->ScrollToTile(current_tile16_);
return;
}
// Fallback: maintain legacy behavior when the selector is unavailable.
constexpr int kTilesPerRow = 8;
constexpr int kTileDisplaySize = 32;
int tile_col = current_tile16_ % kTilesPerRow;
int tile_row = current_tile16_ / kTilesPerRow;
float tile_x = static_cast<float>(tile_col * kTileDisplaySize);
float tile_y = static_cast<float>(tile_row * kTileDisplaySize);
const ImVec2 window_size = ImGui::GetWindowSize();
float scroll_x = tile_x - (window_size.x / 2.0F) + (kTileDisplaySize / 2.0F);
float scroll_y = tile_y - (window_size.y / 2.0F) + (kTileDisplaySize / 2.0F);
// ❌ BUG: This scrolls whatever ImGui window is currently active!
// When called from overworld canvas, it scrolls the overworld instead of tile16 selector!
ImGui::SetScrollX(std::max(0.0f, scroll_x));
ImGui::SetScrollY(std::max(0.0f, scroll_y));
}
```
**After (FIXED)**:
```cpp
void OverworldEditor::ScrollBlocksetCanvasToCurrentTile() {
if (blockset_selector_) {
blockset_selector_->ScrollToTile(current_tile16_); // Correct: Targets specific canvas
return;
}
// CRITICAL FIX: Do NOT use fallback scrolling from overworld canvas context!
// The fallback code uses ImGui::SetScrollX/Y which scrolls the CURRENT window,
// and when called from CheckForSelectRectangle() during overworld canvas rendering,
// it incorrectly scrolls the overworld canvas instead of the tile16 selector.
//
// The blockset_selector_ should always be available in modern code paths.
// If it's not available, we skip scrolling rather than scroll the wrong window.
}
```
**Why This Fixes It**:
- The modern `blockset_selector_->ScrollToTile()` targets the specific tile16 selector canvas
- The fallback `ImGui::SetScrollX/Y()` has no context - it just scrolls the active window
- By removing the fallback, we prevent scrolling the wrong canvas
- If `blockset_selector_` is null (shouldn't happen in modern builds), we safely do nothing instead of breaking user interaction
## Issue 4: Wrong Hover Check (Line 1403)
**File**: `src/app/editor/overworld/overworld_editor.cc:1403`
**Problem**: The code was using `ImGui::IsItemHovered()` to check if the mouse was over the canvas, but this checks the **last drawn ImGui item**, which could be entities, overlays, or anything drawn after the canvas's InvisibleButton. This meant hover detection was completely broken.
**Call Stack**:
```
DrawOverworldCanvas()
└─ DrawBackground() at line 1350 // Creates InvisibleButton (item A)
└─ DrawExits/Entrances/Items/Sprites() // Draws entities (items B, C, D...)
└─ DrawOverlayPreviewOnMap() // Draws overlay (item E)
└─ IsItemHovered() at line 1403 // ❌ Checks item E, not item A!
```
**Before (BROKEN)**:
```cpp
if (current_mode == EditingMode::DRAW_TILE) {
CheckForOverworldEdits();
}
if (IsItemHovered()) // ❌ Checks LAST item (overlay/entity), not canvas!
status_ = CheckForCurrentMap();
```
**After (FIXED)**:
```cpp
if (current_mode == EditingMode::DRAW_TILE) {
CheckForOverworldEdits();
}
// CRITICAL FIX: Use canvas hover state, not ImGui::IsItemHovered()
// IsItemHovered() checks the LAST drawn item, which could be entities/overlay,
// not the canvas InvisibleButton. ow_map_canvas_.IsMouseHovering() correctly
// tracks whether mouse is over the canvas area.
if (ow_map_canvas_.IsMouseHovering()) // Checks canvas hover state directly
status_ = CheckForCurrentMap();
```
**Why This Fixes It**:
- `IsItemHovered()` is context-sensitive - it checks whatever the last `ImGui::*()` call was
- After drawing entities and overlays, the "last item" is NOT the canvas
- `Canvas::IsMouseHovering()` tracks the hover state from the InvisibleButton in `DrawBackground()`
- This state is set correctly when the InvisibleButton is hovered (line 416 in canvas.cc)
## Issue 5: Vanilla Large Map World Offset (Line 1132-1136)
**File**: `src/app/editor/overworld/overworld_editor.cc:1132-1136`
**Problem**: For vanilla ROMs, the large map highlighting logic wasn't accounting for world offsets when calculating parent map coordinates. Dark World maps (0x40-0x7F) and Special World maps (0x80-0x9F) use map IDs with offsets, but the display grid coordinates are 0-7.
**Before (BROKEN)**:
```cpp
if (overworld_.overworld_map(current_map_)->is_large_map() ||
overworld_.overworld_map(current_map_)->large_index() != 0) {
const int highlight_parent =
overworld_.overworld_map(current_highlighted_map)->parent();
const int parent_map_x = highlight_parent % 8; // ❌ Wrong for Dark/Special!
const int parent_map_y = highlight_parent / 8;
ow_map_canvas_.DrawOutline(parent_map_x * kOverworldMapSize,
parent_map_y * kOverworldMapSize,
large_map_size, large_map_size);
}
```
**Example Bug**:
- Dark World map 0x42 (parent) → `0x42 % 8 = 2`, `0x42 / 8 = 8`
- This draws the outline at grid position (2, 8) which is **off the screen**!
- Correct position should be (2, 0) in the Dark World display grid
**After (FIXED)**:
```cpp
if (overworld_.overworld_map(current_map_)->is_large_map() ||
overworld_.overworld_map(current_map_)->large_index() != 0) {
const int highlight_parent =
overworld_.overworld_map(current_highlighted_map)->parent();
// CRITICAL FIX: Account for world offset when calculating parent coordinates
int parent_map_x;
int parent_map_y;
if (current_world_ == 0) {
// Light World (0x00-0x3F)
parent_map_x = highlight_parent % 8;
parent_map_y = highlight_parent / 8;
} else if (current_world_ == 1) {
// Dark World (0x40-0x7F) - subtract 0x40 to get display coordinates
parent_map_x = (highlight_parent - 0x40) % 8;
parent_map_y = (highlight_parent - 0x40) / 8;
} else {
// Special World (0x80-0x9F) - subtract 0x80 to get display coordinates
parent_map_x = (highlight_parent - 0x80) % 8;
parent_map_y = (highlight_parent - 0x80) / 8;
}
ow_map_canvas_.DrawOutline(parent_map_x * kOverworldMapSize,
parent_map_y * kOverworldMapSize,
large_map_size, large_map_size);
}
```
**Why This Fixes It**:
- Map IDs are **absolute**: Light World 0x00-0x3F, Dark World 0x40-0x7F, Special 0x80-0x9F
- Display coordinates are **relative**: Each world displays in an 8x8 grid (0-7, 0-7)
- Without subtracting the world offset, coordinates overflow the display grid
- This matches the same logic used for v3 large maps (lines 1084-1096) and small maps (lines 1141-1172)

### Emulator: Critical Performance Fixes
**Console Logging Performance Killer Fixed:**
- **Issue**: Console logging code was executing on EVERY instruction even when disabled, causing severe performance degradation (< 1 FPS)
- **Impact**: ~1,791,000 console writes per second with mutex locks and buffer flushes
- **Fix**: Removed 73 lines of console output from CPU instruction execution hot path
- **Result**: Emulator now runs at full 60 FPS
**Instruction Logging Default Changed:**
- **Changed**: `kLogInstructions` flag default from `true` to `false`
- **Reason**: Even without console spam, logging every instruction to DisassemblyViewer caused significant slowdown
- **Impact**: No logging overhead unless explicitly enabled by user
**Instruction Log Unbounded Growth Fixed:**
- **Issue**: Legacy `instruction_log_` vector growing to 60+ million entries after 10 minutes, consuming 6GB+ RAM
- **Fix**: Added automatic trimming to 10,000 most recent instructions
- **Result**: Memory usage stays bounded at ~50MB
**Audio Buffer Allocation Bug Fixed:**
- **Issue**: Audio buffer allocated as single `int16_t` instead of array, causing immediate buffer overflow
- **Fix**: Properly allocate as array using `new int16_t[size]` with custom deleter
- **Result**: Audio system can now queue samples without corruption
### Emulator: UI Organization & Input System
**New UI Architecture:**
- **Created `src/app/emu/ui/` directory** for separation of concerns
- **EmulatorUI Layer**: Separated all ImGui rendering code from emulator logic
- **Input Abstraction**: `IInputBackend` interface with SDL2 implementation for future SDL3 migration
- **InputHandler**: Continuous polling system using `SDL_GetKeyboardState()` instead of event-based ImGui keys
**Keyboard Input Fixed:**
- **Issue**: Event-based `ImGui::IsKeyPressed()` only fires once per press, doesn't work for held buttons
- **Fix**: New `InputHandler` uses continuous SDL keyboard state polling every frame
- **Result**: Proper game controls with held button detection
**DisassemblyViewer Enhancement:**
- **Sparse Address Map**: Mesen-style storage of unique addresses only, not every execution
- **Execution Counter**: Increments on re-execution for hotspot analysis
- **Performance**: Tracks millions of instructions with ~5MB RAM vs 6GB+ with old system
- **Always Active**: No need for toggle flag, efficiently active by default
**Feature Flags Cleanup:**
- Removed deprecated `kLogInstructions` flag entirely
- DisassemblyViewer now always active with zero performance cost
### Debugger: Breakpoint & Watchpoint Systems
**BreakpointManager:**
- **CRUD Operations**: Add/Remove/Enable/Disable breakpoints with unique IDs
- **Breakpoint Types**: Execute, Read, Write, Access, and Conditional breakpoints
- **Dual CPU Support**: Separate tracking for 65816 CPU and SPC700
- **Hit Counting**: Tracks how many times each breakpoint is triggered
- **CPU Integration**: Connected to CPU execution via callback system
**WatchpointManager:**
- **Memory Access Tracking**: Monitor reads/writes to memory ranges
- **Range-Based**: Watch single addresses or memory regions ($7E0000-$7E00FF)
- **Access History**: Deque-based storage of last 1000 memory accesses
- **Break-on-Access**: Optional execution pause when watchpoint triggered
- **Export**: CSV export of access history for analysis
**CPU Debugger UI Enhancements:**
- **Integrated Controls**: Play/Pause/Step/Reset buttons directly in debugger window
- **Breakpoint UI**: Address input (hex), add/remove buttons, enable/disable checkboxes, hit count display
- **Live Disassembly**: DisassemblyViewer showing real-time execution
- **Register Display**: Real-time CPU state (A, X, Y, D, SP, PC, PB, DB, flags)
### Build System Simplifications
**Eliminated Conditional Compilation:**
- **Before**: Optional flags for JSON (`YAZE_WITH_JSON`), gRPC (`YAZE_WITH_GRPC`), AI (`Z3ED_AI`)
- **After**: All features always enabled, no configuration required
- **Benefits**: Simpler development, easier onboarding, fewer ifdef-related bugs, consistent builds across all platforms
- **Build Command**: Just `cmake -B build && cmake --build build` - no flags needed!
**DisassemblyViewer Performance Limits:**
- Max 10,000 instructions stored (prevents memory bloat)
- Auto-trim to 8,000 when limit reached (keeps hottest code paths)
- Toggle recording on/off for performance testing
- Clear button to free memory
### Build System: Windows Platform Improvements
**gRPC v1.67.1 Upgrade:**
- **Issue**: v1.62.0 had template instantiation errors on MSVC
- **Fix**: Upgraded to v1.67.1 with MSVC template fixes and better C++17/20 compatibility
- **Result**: Builds successfully on Visual Studio 2022
**MSVC-Specific Compiler Flags:**
- `/bigobj` - Allow large object files (gRPC generates many)
- `/permissive-` - Standards conformance mode
- `/wd4267 /wd4244` - Suppress harmless conversion warnings
- `/constexpr:depth2048` - Handle deep template instantiations
**Cross-Platform Validation:**

- No platform-specific code in audio backend or input abstraction
- Ready for SDL3 migration with minimal changes
### GUI & UX Modernization
- **Theme System**: Implemented comprehensive theme system (`AgentUITheme`) centralizing all UI colors
- **UI Helper Library**: Created 30+ reusable UI helper functions reducing boilerplate code by over 50%
- **Visual Polish**: Enhanced UI panels with theme-aware colors, status badges, connection indicators
### Overworld Editor Refactoring
- **Modular Architecture**: Refactored 3,400-line `OverworldEditor` into smaller focused modules
- **Progressive Loading**: Implemented priority-based progressive loading in `gfx::Arena` to prevent UI freezes
- **Critical Graphics Fixes**: Resolved bugs with graphics refresh, multi-quadrant map updates, and feature visibility
- **Multi-Area Map Configuration**: Robust `ConfigureMultiAreaMap()` handling all area sizes
### Build System & Stability
- **Build Fixes**: Resolved 7 critical build errors including linker issues and filesystem crashes
- **C API Separation**: Decoupled C API library from main application for improved modularity
### Future Optimizations (Planned)
**Graphics System:**
- Lazy loading of graphics sheets (load on-demand rather than all at once)
- Heap-based allocation for large data structures instead of stack
- Streaming/chunked loading for large ROM assets
- Consider if all 223 sheets need to be in memory simultaneously
**Build System:**
- Further reduce CI build times
- Enhanced dependency caching strategies
- Improved vcpkg integration reliability
### Technical Notes
**Breaking Changes:**
- None - this is a patch release focused on stability and fixes
**Deprecations:**
- None
**Migration Guide:**
- No migration required - this release is fully backward compatible with 0.3.1

status = stub.GetDebugStatus(Empty())
# Check for crashes or freezes
if status.fps < 30:
print(f"ANOMALY: Low FPS detected ({status.fps:.2f})")
save_crash_dump(status)
# Check for memory corruption
health = stub.ReadMemory(MemoryRequest(
address=0x7EF36D, size=1
))
if health.data[0] > 0xA8: # Max health
print(f"BUG: Health overflow! Value: {health.data[0]:02X}")
stub.Pause(Empty())
break
```

# A Link to the Past ROM Reference
## Graphics System
### Graphics Sheets
The ROM contains 223 graphics sheets, each 128x32 pixels (16 tiles × 4 tiles, 8×8 tile size):
**Sheet Categories**:
- Sheets 0-112: Overworld/Dungeon graphics (compressed 3BPP)
- Sheets 113-114: Uncompressed 2BPP graphics
- Sheets 115-126: Uncompressed 3BPP graphics
- Sheets 127-217: Additional dungeon/sprite graphics
- Sheets 218-222: Menu/HUD graphics (2BPP)
**Graphics Format**:
- 3BPP (3 bits per pixel): 8 colors per tile, commonly used for backgrounds
- 2BPP (2 bits per pixel): 4 colors per tile, used for fonts and simple graphics
### Palette System
#### Color Format
SNES uses 15-bit BGR555 color format:
- 2 bytes per color
- Format: `0BBB BBGG GGGR RRRR`
- Each channel: 0-31 (5 bits)
- Total possible colors: 32,768
**Conversion Formulas:**
```cpp
// From BGR555 to RGB888 (0-255 range)
uint8_t red = (snes_color & 0x1F) * 8;
uint8_t green = ((snes_color >> 5) & 0x1F) * 8;
uint8_t blue = ((snes_color >> 10) & 0x1F) * 8;
// From RGB888 to BGR555
uint16_t snes_color = ((r / 8) & 0x1F) |
(((g / 8) & 0x1F) << 5) |
(((b / 8) & 0x1F) << 10);
```
#### 16-Color Row Structure
The SNES organizes palettes in **rows of 16 colors**:
- Each row starts with a **transparent color** at indices 0, 16, 32, 48, 64, etc.
- Palettes must respect these boundaries for proper display
- Multiple sub-palettes can share a row if they're 8 colors or less
#### Palette Groups
**Dungeon Palettes** (0xDD734):
- 20 palettes × 90 colors each
- Structure: 5 full rows (0-79) + 10 colors (80-89)
- Transparent at: indices 0, 16, 32, 48, 64
- Distributed as: BG1 colors, BG2 colors, sprite colors
- Applied per-room via palette ID
**Overworld Palettes**:
- Main: 35 colors per palette (0xDE6C8)
- Structure: 2 full rows (0-15, 16-31) + 3 colors (32-34)
- Transparent at: 0, 16
- Auxiliary: 21 colors per palette (0xDE86C)
- Structure: 1 full row (0-15) + 5 colors (16-20)
- Transparent at: 0
- Animated: 7 colors per palette (0xDE604)
- Overlay palette (no transparent)
**Sprite Palettes**:
- Global sprites: 2 palettes of 60 colors each
- Light World: 0xDD218
- Dark World: 0xDD290
- Structure: 4 rows per set (0-15, 16-31, 32-47, 48-59)
- Transparent at: 0, 16, 32, 48
- Auxiliary 1: 12 palettes × 7 colors (0xDD39E)
- Auxiliary 2: 11 palettes × 7 colors (0xDD446)
- Auxiliary 3: 24 palettes × 7 colors (0xDD4E0)
- Note: Aux palettes store 7 colors; transparent added at runtime
**Other Palettes**:
- HUD: 2 palettes × 32 colors (0xDD218)
- Structure: 2 full rows (0-15, 16-31)
- Transparent at: 0, 16
- Armors: 5 palettes × 15 colors (0xDD630)
- 15 colors + transparent at runtime = full 16-color row
- Swords: 4 palettes × 3 colors (overlay, no transparent)
- Shields: 3 palettes × 4 colors (overlay, no transparent)
- Grass: 3 individual hardcoded colors (LW, DW, Special)
- 3D Objects: 2 palettes × 8 colors (Triforce, Crystal)
- Overworld Mini Map: 2 palettes × 128 colors
- Structure: 8 full rows (0-127)
- Transparent at: 0, 16, 32, 48, 64, 80, 96, 112
#### Palette Application to Graphics
**8-Color Sub-Palettes:**
- Index 0: Transparent (not rendered)
- Indices 1-7: Visible colors
- Each tile/sprite references a specific 8-color sub-palette
**Graphics Format:**
- 2BPP: 4 colors per tile (uses indices 0-3)
- 3BPP: 8 colors per tile (uses indices 0-7)
- 4BPP: 16 colors per tile (uses indices 0-15)
**Rendering Process:**
1. Load compressed graphics sheet from ROM
2. Decompress and convert to indexed pixels (values 0-7 for 3BPP)
3. Select appropriate palette group for room/area
4. Map pixel indices to actual colors from palette
5. Upload to GPU texture
## Dungeon System
### Room Data Structure
**Room Objects** (3 bytes each):
```
Byte 1: YYYXXXXX
YYY = Y coordinate (0-31)
XXXXX = X coordinate (0-31) + layer flag (bit 5)
Byte 2: SSSSSSSS
Size byte (interpretation varies by object type)
Byte 3: IIIIIIII
Object ID or ID component (0-255)
```
**Object Patterns**:
- 0x34: 1x1 solid block
- 0x00-0x08: Rightward 2x2 expansion
- 0x60-0x68: Downward 2x2 expansion
- 0x09-0x14: Diagonal acute (/)
- 0x15-0x20: Diagonal grave (\)
- 0x33, 0x70-0x71: 4x4 blocks
### Tile16 Format
Each Tile16 is composed of four 8x8 tiles:
```
[Top-Left] [Top-Right]
[Bot-Left] [Bot-Right]
```
Stored as 8 bytes (2 bytes per 8x8 tile):
```cpp
// 16-bit tile info: vhopppcccccccccc
// v = vertical flip
// h = horizontal flip
// o = priority
// ppp = palette index (0-7)
// cccccccccc = tile ID (0-1023)
```
### Blocksets
Each dungeon room uses a blockset defining which graphics sheets are loaded:
- 16 sheets per blockset
- First 8: Background graphics
- Last 8: Sprite graphics
**Blockset Pointer**: 0x0FFC40
## Message System

## Documentation Standards
### Naming Convention
- **A-series**: Getting Started & Testing
- **B-series**: Build, Platform & Git Workflow
- **C-series**: CLI Tools (`z3ed`)
- **E-series**: Development, API & Emulator
- **F-series**: Feature-Specific Technical Docs
- **G-series**: Graphics & GUI Systems
- **H-series**: Project Info (Changelog, etc.)
- **I-series**: Roadmap & Vision
- **R-series**: ROM Technical Reference
### File Naming
- Use descriptive, kebab-case names
- Prefix with series letter and number (e.g., `E4-emulator-development-guide.md`)
- Keep filenames concise but clear
### Organization Tips
For Doxygen integration, this index can be enhanced with:
- `@mainpage` directive to make this the main documentation page
- `@defgroup` to create logical groupings across files
- `@tableofcontents` for automatic TOC generation
- See individual files for `@page` and `@section` usage
### Doxygen Integration Tips
- Add a short `@mainpage` block to `docs/index.md` so generated HTML mirrors the
manual structure.
- Define high-level groups with `@defgroup` (`getting_started`, `building`,
`graphics_gui`, etc.) and attach individual docs using `@page ... @ingroup`.
- Use `@subpage`, `@section`, and `@subsection` when a document benefits from
nested navigation.
- Configure `Doxyfile` with `USE_MDFILE_AS_MAINPAGE = docs/index.md`,
`FILE_PATTERNS = *.md *.h *.cc`, and `EXTENSION_MAPPING = md=C++` to combine
Markdown and source comments.
- Keep Markdown reader-friendly—wrap Doxygen directives in comment fences (`/**`
… `*/`) so they are ignored by GitHub while remaining visible to the
generator.

# vcpkg Integration for Windows Builds
> **Note**: This document provides detailed vcpkg information. For the most up-to-date build instructions, see [Build Instructions](02-build-instructions.md).
This document describes how to use vcpkg for Windows builds in Visual Studio with YAZE.
## Overview
vcpkg is Microsoft's C++ package manager that simplifies dependency management for Windows builds. YAZE now includes full vcpkg integration with manifest mode support for automatic dependency resolution.
## Features
- **Manifest Mode**: Dependencies are automatically managed via `vcpkg.json`
- **Visual Studio Integration**: Seamless integration with Visual Studio 2022
- **Generated Project Files**: Visual Studio project files with proper vcpkg integration
- **CMake Presets**: Pre-configured build presets for Windows
- **Automatic Setup**: Setup scripts for easy vcpkg installation
## Quick Start
### 1. Setup vcpkg
Run the automated setup script:
```powershell
# PowerShell (recommended)
.\scripts\setup-windows-dev.ps1
```
This will:
- Set up vcpkg
- Install dependencies (zlib, libpng, SDL2)
- Generate Visual Studio project files with proper vcpkg integration
### 2. Build with Visual Studio
```powershell
# Generate project files (if not already done)
python scripts/generate-vs-projects.py
# Open YAZE.sln in Visual Studio 2022
# Select configuration and platform, then build
```
### 3. Alternative: Build with CMake
Use the Windows presets in CMakePresets.json:
```cmd
# Debug build
cmake --preset windows-debug
cmake --build build --preset windows-debug
# Release build
cmake --preset windows-release
cmake --build build --preset windows-release
```
## Configuration Details
### vcpkg.json Manifest
The `vcpkg.json` file defines all dependencies:
```json
{
"name": "yaze",
"version": "0.3.1",
"description": "Yet Another Zelda3 Editor",
"dependencies": [
{
"name": "zlib",
"platform": "!uwp"
},
{
"name": "libpng",
"platform": "!uwp"
},
{
"name": "sdl2",
"platform": "!uwp",
"features": ["vulkan"]
}
],
"builtin-baseline": "2024.12.12"
}
```
### CMake Configuration
vcpkg integration is handled in several files:
- **CMakeLists.txt**: Automatic toolchain detection
- **cmake/vcpkg.cmake**: vcpkg-specific settings
- **CMakePresets.json**: Windows build presets
### Build Presets
Available Windows presets:
- `windows-debug`: Debug build with vcpkg
- `windows-release`: Release build with vcpkg
## Dependencies
vcpkg automatically installs these dependencies:
- **zlib**: Compression library
- **libpng**: PNG image support
- **sdl2**: Graphics and input handling (with Vulkan support)
**Note**: Abseil and gtest are now built from source via CMake rather than through vcpkg to avoid compatibility issues.
## Environment Variables
Set `VCPKG_ROOT` to point to your vcpkg installation:
```cmd
set VCPKG_ROOT=C:\path\to\vcpkg
```
## Troubleshooting
### Common Issues
1. **vcpkg not found**: Ensure `VCPKG_ROOT` is set or vcpkg is in the project directory
2. **Dependencies not installing**: Check internet connection and vcpkg bootstrap
3. **Visual Studio integration**: Run `vcpkg integrate install` from vcpkg directory
### Manual Setup
If automated setup fails:
```cmd
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg.exe integrate install
```
## Benefits
- **Consistent Dependencies**: Same versions across development environments
- **Easy Updates**: Update dependencies via vcpkg.json
- **CI/CD Friendly**: Reproducible builds
- **Visual Studio Integration**: Native IntelliSense support
- **No Manual Downloads**: Automatic dependency resolution
## Advanced Usage
### Custom Triplets
Override the default x64-windows triplet:
```cmd
cmake --preset windows-debug -DVCPKG_TARGET_TRIPLET=x86-windows
```
### Static Linking
For static builds, modify `cmake/vcpkg.cmake`:
```cmake
set(VCPKG_LIBRARY_LINKAGE static)
set(VCPKG_CRT_LINKAGE static)
```

# Installing vcpkg Triplets for Windows
This guide explains how to install the `x64-windows` triplet that's required for building YAZE on Windows.
## What is a vcpkg Triplet?
A triplet defines the target platform, architecture, and linking configuration for vcpkg packages. The `x64-windows` triplet is the most common one for 64-bit Windows development.
## Method 1: Install via Package (Recommended)
The easiest way to ensure the triplet is available is to install any package with that triplet:
```cmd
# Navigate to your vcpkg directory
cd C:\path\to\your\vcpkg
# Install a package with the x64-windows triplet
vcpkg install sdl2:x64-windows
```
This will automatically create the triplet configuration if it doesn't exist.
## Method 2: Create Triplet File Manually
If you need to create the triplet configuration manually:
1. **Navigate to vcpkg triplets directory:**
```cmd
cd C:\path\to\your\vcpkg\triplets
```
2. **Create or verify `x64-windows.cmake` exists:**
```cmd
dir x64-windows.cmake
```
3. **If it doesn't exist, create it with this content:**
```cmake
set(VCPKG_TARGET_ARCHITECTURE x64)
set(VCPKG_CRT_LINKAGE dynamic)
set(VCPKG_LIBRARY_LINKAGE dynamic)
set(VCPKG_CMAKE_SYSTEM_NAME Windows)
```
## Method 3: Check Available Triplets
To see what triplets are currently available on your system:
```cmd
vcpkg help triplet
```
Or list all available triplet files:
```cmd
vcpkg help triplet | findstr "Available"
```
## Method 4: Install YAZE Dependencies
Since YAZE uses several vcpkg packages, installing them will ensure the triplet is properly set up:
```cmd
# From the YAZE project root
vcpkg install --triplet x64-windows sdl2 zlib libpng abseil
```
## Common Issues and Solutions
### Issue: "Invalid triplet"
**Solution:** Make sure vcpkg is properly installed and in your PATH:
```cmd
vcpkg version
```
### Issue: "Triplet not found"
**Solution:** Install a package with that triplet first:
```cmd
vcpkg install zlib:x64-windows
```
### Issue: "Permission denied"
**Solution:** Run Command Prompt as Administrator, or install vcpkg in a user-writable location.
## Alternative Triplets
If `x64-windows` doesn't work, you can try these alternatives:
- `x64-windows-static` - Static linking
- `x86-windows` - 32-bit Windows
- `x64-windows-static-md` - Static runtime, dynamic CRT
## Verification
To verify the triplet is working:
```cmd
vcpkg list --triplet x64-windows
```
This should show installed packages for that triplet.
## For YAZE Build
Once the triplet is installed, you can build YAZE using CMake presets:
```cmd
cmake --preset=windows-release
cmake --build build --config Release
```
Or with the Visual Studio solution:
```cmd
# Open yaze.sln in Visual Studio
# Build normally (F5 or Ctrl+Shift+B)
```

cmake --build . --config Debug --target yaze
# For Release Build
cmake --build . --config Release --target yaze
# For Testing (Optional)
cmake --build . --config Debug --target yaze_test
```
## Common Issues and Solutions
### Issue 1: zlib Import Errors
**Problem:** `fatal error C1083: Cannot open include file: 'zlib.h'`
**Solution:**
1. Ensure vcpkg is properly integrated with Visual Studio
2. Verify the vcpkg toolchain file is set:
```cmd
cmake .. -DCMAKE_TOOLCHAIN_FILE=%VCPKG_ROOT%/scripts/buildsystems/vcpkg.cmake
```
3. Check that zlib is installed:
```cmd
vcpkg list zlib
```
### Issue 2: Executable Runs Tests Instead of Main App
**Problem:** Running `yaze.exe` starts the test framework instead of the application
**Solution:** This has been fixed in the latest version. The issue was caused by linking `gtest_main` to the main executable. The fix removes `gtest_main` from the main application while keeping `gtest` for testing capabilities.
### Issue 3: SDL2 Configuration Issues
**Problem:** SDL2 not found or linking errors
**Solution:**
1. Install SDL2 with vcpkg:
```cmd
vcpkg install sdl2[vulkan]:x64-windows
```
2. Ensure the project uses the vcpkg toolchain file
### Issue 4: Build Errors with Abseil
**Problem:** Missing Abseil symbols or linking issues
**Solution:**
1. Install Abseil via vcpkg:
```cmd
vcpkg install abseil:x64-windows
```
2. The project is configured to use Abseil 20240116.2 (see vcpkg.json overrides)
## Visual Studio Configuration
### CMake Settings
Create or modify `.vscode/settings.json` or use Visual Studio's CMake settings:
```json
{
"cmake.configureArgs": [
"-DCMAKE_TOOLCHAIN_FILE=${env:VCPKG_ROOT}/scripts/buildsystems/vcpkg.cmake",

# Windows Development Guide for YAZE
This guide will help you set up a Windows development environment for YAZE and build the project successfully.
## Prerequisites
### Required Software
1. **Visual Studio 2022** (Community, Professional, or Enterprise)
- Download from: https://visualstudio.microsoft.com/downloads/
- Required workloads:
- Desktop development with C++
- Game development with C++ (optional, for additional tools)
2. **Git for Windows**
- Download from: https://git-scm.com/download/win
- Use default installation options
3. **Python 3.8 or later**
- Download from: https://www.python.org/downloads/
- Make sure to check "Add Python to PATH" during installation
### Optional Software
- **PowerShell 7** (recommended for better script support)
- **Windows Terminal** (for better terminal experience)
## Quick Setup
### Automated Setup
The easiest way to get started is to use our automated setup script:
```powershell
# Run from the YAZE project root directory
.\scripts\setup-windows-dev.ps1
```
This script will:
- Check for required software (Visual Studio 2022, Git, Python)
- Set up vcpkg and install dependencies (zlib, libpng, SDL2)
- Generate Visual Studio project files with proper vcpkg integration
- Perform a test build to verify everything works
### Manual Setup
If you prefer to set up manually or the automated script fails:
#### 1. Clone the Repository
```bash
git clone https://github.com/your-username/yaze.git
cd yaze
```
#### 2. Set up vcpkg
```bash
# Clone vcpkg
git clone https://github.com/Microsoft/vcpkg.git vcpkg
# Bootstrap vcpkg
cd vcpkg
.\bootstrap-vcpkg.bat
cd ..
# Install dependencies
.\vcpkg\vcpkg.exe install --triplet x64-windows
```
#### 3. Generate Visual Studio Project Files
The generation script creates project files with proper vcpkg integration:
```bash
python scripts/generate-vs-projects.py
```
This creates:
- `YAZE.sln` - Visual Studio solution file
- `YAZE.vcxproj` - Visual Studio project file with vcpkg integration
- Proper vcpkg triplet settings for all platforms (x86, x64, ARM64)
#### 4. Build the Project
```bash
# Using PowerShell script (recommended)
.\scripts\build-windows.ps1 -Configuration Release -Platform x64
# Or using batch script
.\scripts\build-windows.bat Release x64
# Or using Visual Studio
# Open YAZE.sln in Visual Studio 2022 and build
```
## Building the Project
### Using Visual Studio
1. Open `YAZE.sln` in Visual Studio 2022
2. Select your desired configuration:
- **Debug**: For development and debugging
- **Release**: For optimized builds
- **RelWithDebInfo**: Release with debug information
- **MinSizeRel**: Minimal size release
3. Select your platform:
- **x64**: 64-bit (recommended)
- **x86**: 32-bit
- **ARM64**: ARM64 (if supported)
4. Build the solution (Ctrl+Shift+B)
### Using Command Line
#### PowerShell Script (Recommended)
```powershell
# Build Release x64 (default)
.\scripts\build-windows.ps1
# Build Debug x64
.\scripts\build-windows.ps1 -Configuration Debug -Platform x64
# Build Release x86
.\scripts\build-windows.ps1 -Configuration Release -Platform x86
# Clean build
.\scripts\build-windows.ps1 -Clean
# Verbose output
.\scripts\build-windows.ps1 -Verbose
```
#### Batch Script
```batch
REM Build Release x64 (default)
.\scripts\build-windows.bat
REM Build Debug x64
.\scripts\build-windows.bat Debug x64
REM Build Release x86
.\scripts\build-windows.bat Release x86
```
#### Direct MSBuild
```bash
# Build Release x64
msbuild YAZE.sln /p:Configuration=Release /p:Platform=x64 /p:VcpkgEnabled=true /p:VcpkgManifestInstall=true /m
# Build Debug x64
msbuild YAZE.sln /p:Configuration=Debug /p:Platform=x64 /p:VcpkgEnabled=true /p:VcpkgManifestInstall=true /m
```
## Project Structure
```
yaze/
├── YAZE.sln # Visual Studio solution file (generated)
├── YAZE.vcxproj # Visual Studio project file (generated)
├── vcpkg.json # vcpkg dependencies
├── scripts/ # Build and setup scripts

```
**Note**: The Visual Studio project files (`YAZE.sln`, `YAZE.vcxproj`) are generated automatically and should not be edited manually. If you need to modify project settings, update the generation script instead.
## Troubleshooting
### Common Issues
#### 1. MSBuild Not Found
**Error**: `'msbuild' is not recognized as an internal or external command`
**Solution**:
- Install Visual Studio 2022 with C++ workload
- Or add MSBuild to your PATH:
```bash
# Add to PATH (adjust path as needed)
C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin
```
#### 2. vcpkg Integration Issues
**Error**: `vcpkg.json not found` or dependency resolution fails
**Solution**:
- Ensure vcpkg is properly set up:
```bash
.\scripts\setup-windows-dev.ps1
```
- Or manually set up vcpkg as described in the manual setup section
#### 3. ZLIB or Other Dependencies Not Found
**Error**: `Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)`
**Solution**:
- This usually means vcpkg integration isn't working properly
- Regenerate project files with proper vcpkg integration:
```bash
python scripts/generate-vs-projects.py
```
- Ensure vcpkg is installed and dependencies are available:
```bash
.\vcpkg\vcpkg.exe install --triplet x64-windows
```
#### 4. Python Script Execution Policy
**Error**: `execution of scripts is disabled on this system`
**Solution**:
```powershell
# Run as Administrator
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```
#### 5. Missing Dependencies
**Error**: Linker errors about missing libraries
**Solution**:
- Ensure all dependencies are installed via vcpkg:
```bash
.\vcpkg\vcpkg.exe install --triplet x64-windows
```
- Regenerate project files:
```bash
python scripts/generate-vs-projects.py
```
#### 6. Build Failures
**Error**: Compilation or linking errors
**Solution**:
- Clean and rebuild:
```powershell
.\scripts\build-windows.ps1 -Clean
```
- Check that all source files are included in the project
- Verify that include paths are correct

.\build\bin\Debug\yaze.exe --rom_file=path\to\your\rom.sfc
```
## Performance Tips
### Build Performance
- Use the `/m` flag for parallel builds
- Use SSD storage for better I/O performance
- Exclude build directories from antivirus scanning
- Use Release configuration for final builds
### Development Performance
- Use Debug configuration for development
- Use incremental builds (default in Visual Studio)
- Use RelWithDebInfo for performance testing with debug info
## Advanced Configuration
### Custom Build Configurations
You can create custom build configurations by modifying the Visual Studio project file or using CMake directly.
### Cross-Platform Development
While this guide focuses on Windows, YAZE also supports:
- Linux (Ubuntu/Debian)
- macOS
See the main build instructions for other platforms.

** TODO [#A] Overworld sprites can't be moved on the overworld canvas :bug:
:PROPERTIES:
:CREATED: [2025-01-31]
:END:
- Issue: Sprites are not responding to drag operations
- Location: Overworld canvas interaction
- Impact: Blocks sprite editing workflow
<2024-11-14 Thu>
Been making lots of adjustments and cleaning up old code. Primarily improving the dungeon map editor and supporting bin graphics for my Oracle of Secrets dungeon maps. Additionally, working to support saving for resources like graphics sheets and expanded the project file system.
** TODO [#A] Canvas multi select has issues with large map intersection drawing :bug:
:PROPERTIES:
:CREATED: [2025-01-31]
:END:
- Issue: Selection box rendering incorrect when crossing 512px boundaries
- Location: Canvas selection system
- Note: E2E test exists to reproduce this bug (canvas_selection_test)
<2024-09-07 Sat>
Various header cleanup using the LSP in emacs to detect unused includes.
Making adjustments to font loading so the editor can be opened from terminal/emacs.
Currently the font files and the zeml files require the binary to be relative to `assets/layouts` and `assets/fonts`
I've set it up so that the macOS app bundles the resources into the `yaze.app` so that the binary can be run from anywhere. This will need to be adjusted for other platforms.
** TODO [#B] Right click randomly shows oversized tile16 :bug:ui:
:PROPERTIES:
:CREATED: [2025-01-31]
:END:
- Issue: Context menu displays abnormally large tile16 preview
- Location: Right-click context menu

<2024-09-02 Mon>
Extracted the DisplayPalette function out of the PaletteEditor and into its own standalone function.
** TODO [#B] Overworld Map properties panel popup displaying incorrectly :ui:
:PROPERTIES:
:CREATED: [2025-01-31]
:END:

* Org-Mode Productivity Tips
** Quick Capture Templates
Add to your Emacs config:
#+begin_src emacs-lisp
(setq org-capture-templates
'(("t" "TODO" entry (file+headline "~/Code/yaze/docs/yaze.org" "Active Issues")
"** TODO [#B] %?\n:PROPERTIES:\n:CREATED: %U\n:END:\n")
("b" "Bug" entry (file+headline "~/Code/yaze/docs/yaze.org" "Active Issues")
"** TODO [#A] %? :bug:\n:PROPERTIES:\n:CREATED: %U\n:END:\n")
("f" "Feature" entry (file+headline "~/Code/yaze/docs/yaze.org" "Active Issues")
"** TODO [#B] %? :feature:\n:PROPERTIES:\n:CREATED: %U\n:END:\n")))
#+end_src
** Useful Commands
- =C-c C-t= : Cycle TODO state
- =C-c C-q= : Add tags
- =C-c ,= : Set priority
- =C-c C-x C-s= : Archive DONE items
- =C-c C-v= : View agenda
- =C-c a t= : Global TODO list
- =C-c a m= : Match tags/properties
** Agenda Configuration
#+begin_src emacs-lisp
(setq org-agenda-files '("~/Code/yaze/docs/yaze.org"))
(setq org-agenda-custom-commands
'(("y" "YAZE Active Tasks"
((tags-todo "bug"
((org-agenda-overriding-header "Active Bugs")))
(tags-todo "feature"
((org-agenda-overriding-header "Features in Development")))
(todo "ACTIVE"
((org-agenda-overriding-header "Currently Working On")))))))
#+end_src
** Workflow Tips
1. Use =C-c C-c= on headlines to update statistics cookies [/] and [%]
2. Create custom views with =org-agenda-custom-commands=
3. Use =org-refile= (C-c C-w) to reorganize tasks
4. Archive completed tasks regularly
5. Use =org-sparse-tree= (C-c /) to filter by TODO state or tags
6. Link to documentation: =[[file:E7-tile16-editor-palette-system.md]]=
7. Track time with =C-c C-x C-i= (clock in) and =C-c C-x C-o= (clock out)
