+# Getting Started
+
+This software allows you to modify "The Legend of Zelda: A Link to the Past" (US or JP) ROMs. Built for compatibility with ZScream projects and designed to be cross-platform.
+
+## Quick Start
+
+1. **Download** the latest release for your platform
+2. **Load ROM** via File > Open ROM
+3. **Select Editor** from the toolbar (Overworld, Dungeon, Graphics, etc.)
+4. **Make Changes** and save your project
+
+## General Tips
+
+- **Experiment Flags**: Enable/disable features in File > Options > Experiment Flags
+- **Backup Files**: Enabled by default - each save creates a timestamped backup
+- **Extensions**: Load custom tools via the Extensions menu (C library and Python module support)
+
+## Supported Features
+
+| Feature | Status | Details |
+|---------|--------|---------|
+| Overworld Maps | ✅ Complete | Edit and save tile32 data |
+| OW Map Properties | ✅ Complete | Edit and save map properties |
+| OW Entrances | ✅ Complete | Edit and save entrance data |
+| OW Exits | ✅ Complete | Edit and save exit data |
+| OW Sprites | 🔄 In Progress | Edit sprite positions, add/remove sprites |
+| Dungeon Editor | 🔄 In Progress | View room metadata and edit room data |
+| Palette Editor | 🔄 In Progress | Edit and save palettes, palette groups |
+| Graphics Sheets | 🔄 In Progress | Edit and save graphics sheets |
+| Graphics Groups | ✅ Complete | Edit and save graphics groups |
+| Hex Editor | ✅ Complete | View and edit ROM data in hex |
+| Asar Patching | ✅ Complete | Apply Asar 65816 assembly patches to ROM |
+
+## Command Line Interface
+
+The `z3ed` CLI tool provides ROM operations:
+
+```bash
+# Apply Asar assembly patch
+z3ed asar patch.asm --rom=zelda3.sfc
+
+# Extract symbols from assembly
+z3ed extract patch.asm
+
+# Validate assembly syntax
+z3ed validate patch.asm
+
+# Launch interactive TUI
+z3ed --tui
+```
+
+## Extending Functionality
+
+YAZE provides a pure C library interface and Python module for building extensions and custom sprites without assembly. Load these under the Extensions menu.
+
+This feature is still in development and not fully documented yet.

+# 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**

+    SD = ZELDA3_VERSION_SD,
+    RANDO = ZELDA3_VERSION_RANDO,
+} zelda3_version;
+```
+
+#### SNES Graphics
+```c
+typedef struct snes_color {
+    uint16_t raw;               // Raw 15-bit SNES color
+    uint8_t red;               // Red component (0-31)

+```
+
+## 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
+} yaze_status;
+```
+
+### 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_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

+
+## 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 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
+
+```bash
+# Development workflow
+cmake --preset dev
+cmake --build --preset dev
+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
+```
+
+## 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...
+}
+```
+
+### 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());
+}
+```
+
+### Experimental Tests
+```cpp
+TEST(CpuTest, InstructionExecution) {
+    // Complex emulation tests
+    // May be timing-sensitive or platform-dependent
+}
+```
+
+## 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

+# Build Presets Guide
+
+CMake presets for development workflow and architecture-specific builds.
+
+## 🍎 macOS ARM64 Presets (Recommended for Apple Silicon)
+
+### For Development Work:
+```bash
+# ARM64-only development build with ROM testing
+cmake --preset macos-dev
+cmake --build --preset macos-dev
+
+# ARM64-only debug build 
+cmake --preset macos-debug
+cmake --build --preset macos-debug
+
+# ARM64-only release build
+cmake --preset macos-release  
+cmake --build --preset macos-release
+```
+
+### For Distribution:
+```bash
+# Universal binary (ARM64 + x86_64) - use only when needed for distribution
+cmake --preset macos-debug-universal
+cmake --build --preset macos-debug-universal
+
+cmake --preset macos-release-universal
+cmake --build --preset macos-release-universal
+```
+
+## 🔧 Why This Fixes Architecture Errors
+
+**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'"
+
+**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)
+
+## 📋 Available 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 |
+
+## 🚀 Quick Start
+
+For most development work on Apple Silicon:
+
+```bash
+# Clean build
+rm -rf build
+
+# Configure for ARM64 development
+cmake --preset macos-dev
+
+# Build
+cmake --build --preset macos-dev
+
+# Run tests  
+cmake --build --preset macos-dev --target test
+```
+
+## 🛠️ IDE Integration
+
+### 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`
+

+open build/yaze.xcodeproj
+```
+
+## 🔍 Troubleshooting
+
+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`
+
+```bash
+# Verify architecture setting
+cmake --preset macos-debug
+grep -A 5 -B 5 "CMAKE_OSX_ARCHITECTURES" build/CMakeCache.txt
+```
+
+## 📝 Notes
+
+- **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

+# Asm Style Guide
+
+65816 Assembly is the assembly language used by the Super Nintendo Entertainment System (SNES) and its Ricoh 5A22 processor. This style guide provides conventions and best practices for writing 65816 assembly code in the context of the yaze project. Following these guidelines will help maintain consistency and readability across the codebase.
+
+This guide is based primarily on the [Oracle of Secrets](https://github.com/scawful/Oracle-of-Secrets) codebase and is meant for the [Asar](https://github.com/RPGHacker/asar) assembler and derives influence from the [Asar 1.9 Manual](https://rpghacker.github.io/asar/asar_19/manual/).
+
+Custom assembly code applied to the game should be included through the `yaze.asm` file found in `assets/asm`. This file can be applied to the ROM by the editor using the Asar library or included into a projects codebase for use with the Asar assembler.
+
+## Table of Contents
+
+- [File Structure](#file-structure)
+- [Labels and Symbols](#labels-and-symbols)
+- [Comments](#comments)
+- [Directives](#directives)
+- [Instructions](#instructions)
+- [Macros](#macros)
+- [Loops and Branching](#loops-and-branching)
+- [Data Structures](#data-structures)
+- [Code Organization](#code-organization)
+- [Custom Code](#custom-code)
+
+
+## File Structure
+
+- **File Extension**: Use `.asm` as the file extension for 65816 assembly files.
+- **Header Comments**: Include a header comment at the beginning of each file describing its purpose and the author.
+
+Example:
+
+```asm
+; =========================================================
+; Purpose: [Brief description of the file’s functionality]
+; Author: [Your Name]
+; =========================================================
+```
+
+- **Section Headers**: Use clear and consistent section headers to divide code into logical blocks. Each major section (e.g., sprite properties, main logic, subroutines) should start with a delineated header.
+
+Example:
+
+```asm
+; =========================================================
+; Minecart Sprite Properties
+; =========================================================
+```
+
+- **Macro Definitions and Includes**: Place macros and include directives at the beginning of the file to keep them organized and easily accessible.
+
+## Labels and Symbols
+
+- **Naming Conventions**:
+  - **Global Labels**: Use descriptive names in `PascalCase` for global labels (e.g., `Sprite_Minecart_Main`).
+  - **Local Labels**: Prefix local labels with a dot (`.`) to indicate their limited scope (e.g., `.check_direction`).
+  - **Constants and Flags**: Use `ALL_CAPS_WITH_UNDERSCORES` for constants and flags (e.g., `!MINECART_SPEED`, `!HARVESTING_FLAG`).
+  - **Variables**: Use `CamelCase` for variable names to maintain readability (e.g., `LinkInCart`, `SpriteDirection`).
+
+- **Alignment**: Align labels to the left margin for better readability. Indent instructions and comments to separate them from labels.
+
+Example:
+
+```asm
+Sprite_Minecart_Main:
+{
+    JSR HandleTileDirections
+    JSR HandleDynamicSwitchTileDirections
+    RTS
+}
+```
+
+## Comments
+
+- **Purpose**: Comments should explain why the code exists and what it is intended to do, especially for complex logic.
+- **Placement**:
+  - Comments can be placed above the code block they describe for longer explanations.
+  - Inline comments can be used for single lines of code where the purpose might not be immediately clear.
+- **Clarity**: Avoid stating the obvious. Focus on explaining the logic rather than restating the code.
+
+Example:
+
+```asm
+LDA $22 : SEC : SBC $3F : STA $31   ; Adjust X position for camera movement
+```
+
+## Instructions
+
+- **Single Line Instructions**: Combine multiple instructions on a single line using colons (`:`) where appropriate for related operations.
+- **Separation**: Use line breaks to separate distinct sections of code logically, improving readability.
+- **Optimization**: Always consider the most efficient instruction for the task at hand, especially in performance-critical sections.
+
+Example:
+
+```asm
+LDA #$01 : STA !LinkInCart  ; Set Link in cart flag
+```
+
+## Macros
+
+- **Naming**: Use `PascalCase` for macro names, with the first letter of each word capitalized (e.g., `InitMovement`, `MoveCart`).
+- **Parameters**: Clearly define and document parameters within macros to ensure they are used correctly.
+- **Reuse**: Encourage the reuse of macros to avoid code duplication and simplify maintenance.
+
+Example:
+
+```asm
+%macro HandlePlayerCamera
+  LDA $22 : SEC : SBC $3F : STA $31
+  LDA $20 : SEC : SBC $3E : STA $30
+  JSL Link_HandleMovingAnimation_FullLongEntry
+  JSL HandleIndoorCameraAndDoors
+  RTS
+endmacro
+```
+
+## Loops and Branching
+
+- **Branch Labels**: Use meaningful names for branch labels, prefixed with a dot (`.`) for local branches.
+- **Optimization**: Minimize the number of instructions within loops and branches to improve performance.
+
+Example:
+
+```asm
+  .loop_start
+  LDA $00 : CMP #$10 : BEQ .end_loop
+    INC $00
+    BRA .loop_start
+  .end_loop
+  RTS
+```
+
+## Data Structures
+
+- **Alignment**: Align data tables and structures clearly, and use comments to describe the purpose and layout of each.
+- **Access**: Ensure that data structures are accessed consistently, with clear boundaries between read and write operations.
+
+Example:
+
+```asm
+.DirectionTileLookup
+{
+  db $02, $00, $04, $00 ; North
+  db $00, $00, $03, $01 ; East
+  db $00, $02, $00, $04 ; South
+  db $03, $01, $00, $00 ; West
+}
+```
+
+- **Structs**: Use structs to group related data together, improving readability and maintainability.
+
+Example:
+
+```asm
+struct AncillaAdd_HookshotData $099AF8
+  .speed_y: skip 4
+  .speed_x: skip 4
+  .offset_y: skip 8
+  .offset_x: skip 8
+endstruct
+
+AncillaAdd_Hookshot:
+  ; $099AF0
+  .speed_y
+  db -64 ; up
+  db  64 ; down
+  db   0 ; left
+  db   0 ; right
+  ; $099AFC
+  .speed_x
+  db   0 ; up
+  db   0 ; down
+  db -64 ; left
+  db  64 ; right
+  ; $099B00
+  .offset_y
+  dw   4 ; up
+  dw  20 ; down
+  dw   8 ; left
+  dw   8 ; right
+  ; $099B08
+  .offset_x
+  dw   0 ; up
+  dw   0 ; down
+  dw  -4 ; left
+  dw  11 ; right
+```
+
+## Code Organization
+
+- **Logical Grouping**: Organize code into logical sections, with related routines and macros grouped together.
+- **Separation of Concerns**: Ensure that each section of code is responsible for a specific task or set of related tasks, avoiding tightly coupled code.
+- **Modularity**: Write code in a modular way, making it easier to reuse and maintain.
+
+Example:
+
+```asm
+; =========================================================
+; Minecart Sprite Logic
+; =========================================================
+Sprite_Minecart_Main:
+{
+  PHX
+  JSR HandleMinecartMovement
+  PLX
+
+  REP #$20
+  LDA !SpriteDirection : STA $00
+  SEP #$20
+  RTS
+}
+```
+
+## Custom Code
+
+- **Integration**: Include custom assembly code in the `yaze.asm` file to ensure it is applied correctly to the ROM. The module should include a define and conditional statement to allow users to disable the module if needed.
+
+Example:
+
+```asm
+!YAZE_CUSTOM_MOSAIC = 1
+
+if !YAZE_CUSTOM_MOSAIC != 0
+  incsrc "mosaic_change.asm"
+endif
+```

+
+## 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

+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

+
+## 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.

+# 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
+- ROM data integration
+- Visual object browsing
+
+## Best Practices
+
+### Performance
+1. **Use Render Caching**: Don't clear cache unnecessarily
+2. **Bounds Checking**: Only render visible objects
+3. **Lazy Loading**: Load graphics and objects on-demand
+4. **Efficient Callbacks**: Minimize callback frequency

+# Overworld Loading Guide
+
+This document provides a comprehensive guide to understanding how overworld loading works in both ZScream (C#) and yaze (C++), including the differences between vanilla ROMs and ZSCustomOverworld v2/v3 ROMs.

+6. [Yaze Implementation](#yaze-implementation)
+7. [Key Differences](#key-differences)
+8. [Common Issues and Solutions](#common-issues-and-solutions)
+
+## Overview
+
+Both ZScream and yaze are Zelda 3 ROM editors that support editing overworld maps. They handle three main types of ROMs:
+
+- **Vanilla ROMs**: Original Zelda 3 ROMs without modifications
+- **ZSCustomOverworld v2**: ROMs with expanded overworld features
+- **ZSCustomOverworld v3**: ROMs with additional features like overlays and custom background colors
+
+## ROM Types and Versions
+
+### Version Detection
+
+Both editors detect the ROM version using the same constant:
+
+```cpp
+// Address: 0x140145
+constexpr int OverworldCustomASMHasBeenApplied = 0x140145;
+
+// Version values:
+// 0xFF = Vanilla ROM
+// 0x02 = ZSCustomOverworld v2
+// 0x03 = ZSCustomOverworld v3
+```
+
+### Feature Support by Version
+
+| Feature | Vanilla | v2 | v3 |
+|---------|---------|----|----| 
+| Basic Overworld Maps | ✅ | ✅ | ✅ |
+| Area Size Enum | ❌ | ❌ | ✅ |
+| Main Palette | ❌ | ✅ | ✅ |
+| Custom Background Colors | ❌ | ✅ | ✅ |
+| Subscreen Overlays | ✅ | ✅ | ✅ |
+| Animated GFX | ❌ | ❌ | ✅ |
+| Custom Tile Graphics | ❌ | ❌ | ✅ |
+| Vanilla Overlays | ✅ | ✅ | ✅ |
+
+**Note:** Subscreen overlays are visual effects (fog, rain, backgrounds, etc.) that are shared between vanilla ROMs and ZSCustomOverworld. ZSCustomOverworld v2+ expands on this by adding support for custom overlay configurations and additional overlay types.
+
+## Overworld Map Structure
+
+### Core Properties
+
+Each overworld map contains the following core properties:
+
+```cpp
+class OverworldMap {
+  // Basic properties
+  uint8_t index_;                    // Map index (0-159)
+  uint8_t parent_;                   // Parent map ID
+  uint8_t world_;                    // World type (0=LW, 1=DW, 2=SW)
+  uint8_t game_state_;               // Game state (0=Beginning, 1=Zelda, 2=Agahnim)
+  
+  // Graphics and palettes
+  uint8_t area_graphics_;            // Area graphics ID
+  uint8_t area_palette_;             // Area palette ID
+  uint8_t main_palette_;             // Main palette ID (v2+)
+  std::array<uint8_t, 3> sprite_graphics_;  // Sprite graphics IDs
+  std::array<uint8_t, 3> sprite_palette_;   // Sprite palette IDs
+  
+  // Map properties
+  uint16_t message_id_;              // Message ID
+  bool mosaic_;                      // Mosaic effect enabled
+  bool large_map_;                   // Is large map (vanilla)
+  AreaSizeEnum area_size_;           // Area size (v3)
+  
+  // Custom features (v2/v3)
+  uint16_t area_specific_bg_color_;  // Custom background color
+  uint16_t subscreen_overlay_;       // Subscreen overlay ID (references special area maps)
+  uint8_t animated_gfx_;             // Animated graphics ID
+  std::array<uint8_t, 8> custom_gfx_ids_;  // Custom tile graphics
+  
+  // Overlay support (vanilla and custom)
+  uint16_t vanilla_overlay_id_;      // Vanilla overlay ID
+  bool has_vanilla_overlay_;         // Has vanilla overlay data
+  std::vector<uint8_t> vanilla_overlay_data_;  // Raw overlay data
+};
+```
+
+## Overlays and Special Area Maps
+
+### Understanding Overlays
+
+Overlays in Zelda 3 are **visual effects** that are displayed over or behind the main overworld map. They include effects like fog, rain, canopy, backgrounds, and other atmospheric elements. Overlays are collections of tile positions and tile IDs that specify where to place specific graphics on the map.
+
+### Special Area Maps (0x80-0x9F)
+
+The special area maps (0x80-0x9F) contain the actual tile data for overlays. These maps store the graphics that overlays reference and use to create visual effects:
+
+- **0x80-0x8F**: Various special area maps containing overlay graphics
+- **0x90-0x9F**: Additional special area maps including more overlay graphics
+
+### Overlay ID Mappings
+
+Overlay IDs directly correspond to special area map indices. Common overlay mappings:
+
+| Overlay ID | Special Area Map | Description |
+|------------|------------------|-------------|
+| 0x0093 | 0x93 | Triforce Room Curtain |
+| 0x0094 | 0x94 | Under the Bridge |
+| 0x0095 | 0x95 | Sky Background (LW Death Mountain) |
+| 0x0096 | 0x96 | Pyramid Background |
+| 0x0097 | 0x97 | First Fog Overlay (Master Sword Area) |
+| 0x009C | 0x9C | Lava Background (DW Death Mountain) |
+| 0x009D | 0x9D | Second Fog Overlay (Lost Woods/Skull Woods) |
+| 0x009E | 0x9E | Tree Canopy (Forest) |
+| 0x009F | 0x9F | Rain Effect (Misery Mire) |
+
+### Drawing Order
+
+Overlays are drawn in a specific order based on their type:
+
+- **Background Overlays** (0x95, 0x96, 0x9C): Drawn behind the main map tiles
+- **Foreground Overlays** (0x9D, 0x97, 0x93, 0x94, 0x9E, 0x9F): Drawn on top of the main map tiles with transparency
+
+### Vanilla Overlay Loading
+
+In vanilla ROMs, overlays are loaded by parsing SNES assembly-like commands that specify tile positions and IDs:
+
+```cpp
+absl::Status LoadVanillaOverlay() {
+  uint8_t asm_version = (*rom_)[OverworldCustomASMHasBeenApplied];
+  
+  // Only load vanilla overlays for vanilla ROMs
+  if (asm_version != 0xFF) {
+    has_vanilla_overlay_ = false;
+    return absl::OkStatus();
+  }
+  
+  // Load overlay pointer for this map
+  int address = (kOverlayPointersBank << 16) +
+                ((*rom_)[kOverlayPointers + (index_ * 2) + 1] << 8) +
+                (*rom_)[kOverlayPointers + (index_ * 2)];
+  
+  // Parse overlay commands:
+  // LDA #$xxxx - Load tile ID into accumulator
+  // LDX #$xxxx - Load position into X register  
+  // STA $xxxx - Store tile at position
+  // STA $xxxx,x - Store tile at position + X
+  // INC A - Increment accumulator (for sequential tiles)
+  // JMP $xxxx - Jump to another overlay routine
+  // END (0x60) - End of overlay data
+  
+  return absl::OkStatus();
+}
+```
+
+### Special Area Graphics Loading
+
+Special area maps require special handling for graphics loading:
+
+```cpp
+void LoadAreaInfo() {
+  if (parent_ >= kSpecialWorldMapIdStart) {
+    // Special World (SW) areas
+    if (asm_version >= 3 && asm_version != 0xFF) {
+      // Use expanded sprite tables for v3
+      sprite_graphics_[0] = (*rom_)[kOverworldSpecialSpriteGfxGroupExpandedTemp + 
+                                     parent_ - kSpecialWorldMapIdStart];
+    } else {
+      // Use original sprite tables for v2/vanilla
+      sprite_graphics_[0] = (*rom_)[kOverworldSpecialGfxGroup + 
+                                     parent_ - kSpecialWorldMapIdStart];
+    }
+    
+    // Handle special cases for specific maps
+    if (index_ == 0x88 || index_ == 0x93) {
+      area_graphics_ = 0x51;
+      area_palette_ = 0x00;
+    } else if (index_ == 0x95) {
+      // Make this the same GFX as LW death mountain areas
+      area_graphics_ = (*rom_)[kAreaGfxIdPtr + 0x03];
+      area_palette_ = (*rom_)[kOverworldMapPaletteIds + 0x03];
+    } else if (index_ == 0x96) {
+      // Make this the same GFX as pyramid areas
+      area_graphics_ = (*rom_)[kAreaGfxIdPtr + 0x5B];
+      area_palette_ = (*rom_)[kOverworldMapPaletteIds + 0x5B];
+    } else if (index_ == 0x9C) {
+      // Make this the same GFX as DW death mountain areas
+      area_graphics_ = (*rom_)[kAreaGfxIdPtr + 0x43];
+      area_palette_ = (*rom_)[kOverworldMapPaletteIds + 0x43];
+    }
+  }
+}
+```
+
+## Loading Process
+
+### 1. Version Detection
+
+Both editors first detect the ROM version:
+
+```cpp
+uint8_t asm_version = rom[OverworldCustomASMHasBeenApplied];
+```
+
+### 2. Map Initialization
+
+For each of the 160 overworld maps (0x00-0x9F):
+
+```cpp
+// ZScream
+var map = new OverworldMap(index, overworld);
+
+// Yaze
+OverworldMap map(index, rom);
+```
+
+### 3. Property Loading
+
+The loading process varies by ROM version:
+
+#### Vanilla ROMs (asm_version == 0xFF)
+
+```cpp
+void LoadAreaInfo() {
+  // Load from vanilla tables
+  message_id_ = rom[kOverworldMessageIds + index_ * 2];
+  area_graphics_ = rom[kOverworldMapGfx + index_];
+  area_palette_ = rom[kOverworldMapPaletteIds + index_];
+  
+  // Determine large map status
+  large_map_ = (rom[kOverworldMapSize + index_] != 0);
+  
+  // Load vanilla overlay
+  LoadVanillaOverlay();
+}
+```
+
+#### ZSCustomOverworld v2/v3
+
+```cpp
+void LoadAreaInfo() {
+  // Use expanded tables for v3
+  if (asm_version >= 3) {
+    message_id_ = rom[kOverworldMessagesExpanded + index_ * 2];
+    area_size_ = static_cast<AreaSizeEnum>(rom[kOverworldScreenSize + index_]);
+  } else {
+    message_id_ = rom[kOverworldMessageIds + index_ * 2];
+    area_size_ = large_map_ ? LargeArea : SmallArea;
+  }
+  
+  // Load custom overworld data
+  LoadCustomOverworldData();
+}
+```
+
+### 4. Custom Data Loading
+
+For ZSCustomOverworld ROMs:
+
+```cpp
+void LoadCustomOverworldData() {
+  // Load main palette
+  main_palette_ = rom[OverworldCustomMainPaletteArray + index_];
+  
+  // Load custom background color
+  if (rom[OverworldCustomAreaSpecificBGEnabled] != 0) {
+    area_specific_bg_color_ = rom[OverworldCustomAreaSpecificBGPalette + index_ * 2];
+  }
+  
+  // Load v3 features
+  if (asm_version >= 3) {
+    subscreen_overlay_ = rom[OverworldCustomSubscreenOverlayArray + index_ * 2];
+    animated_gfx_ = rom[OverworldCustomAnimatedGFXArray + index_];
+    
+    // Load custom tile graphics (8 sheets)
+    for (int i = 0; i < 8; i++) {
+      custom_gfx_ids_[i] = rom[OverworldCustomTileGFXGroupArray + index_ * 8 + i];
+    }
+  }
+}
+```
+
+## ZScream Implementation
+
+### OverworldMap Constructor
+
+```csharp
+public OverworldMap(byte index, Overworld overworld) {
+    Index = index;
+    this.overworld = overworld;
+    
+    // Load area info
+    LoadAreaInfo();
+    
+    // Load custom data if available
+    if (ROM.DATA[Constants.OverworldCustomASMHasBeenApplied] != 0xFF) {
+        LoadCustomOverworldData();
+    }
+    
+    // Build graphics and palette
+    BuildMap();
+}
+```
+
+### Key Methods
+
+- `LoadAreaInfo()`: Loads basic map properties from ROM
+- `LoadCustomOverworldData()`: Loads ZSCustomOverworld features
+- `LoadPalette()`: Loads and processes palette data
+- `BuildMap()`: Constructs the final map bitmap
+
+**Note**: ZScream is the original C# implementation that yaze is designed to be compatible with.
+
+## Yaze Implementation
+
+### OverworldMap Constructor
+
+```cpp
+OverworldMap::OverworldMap(int index, Rom* rom) : index_(index), rom_(rom) {
+  LoadAreaInfo();
+  LoadCustomOverworldData();
+  SetupCustomTileset(asm_version);
+}
+```
+
+### Key Methods
+
+- `LoadAreaInfo()`: Loads basic map properties
+- `LoadCustomOverworldData()`: Loads ZSCustomOverworld features  
+- `LoadVanillaOverlay()`: Loads vanilla overlay data
+- `LoadPalette()`: Loads and processes palette data
+- `BuildTileset()`: Constructs graphics tileset
+- `BuildBitmap()`: Creates the final map bitmap
+
+### 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
+✅ **Graphics Loading**: Optimized with caching and performance monitoring
+
+## Key Differences
+
+### 1. Language and Architecture
+
+| Aspect | ZScream | Yaze |
+|--------|---------|------|
+| Language | C# | C++ |
+| Memory Management | Garbage Collected | Manual (RAII) |
+| Graphics | System.Drawing | Custom OpenGL |
+| UI Framework | WinForms | ImGui |
+
+### 2. Data Structures
+
+**ZScream:**
+```csharp
+public class OverworldMap {
+    public byte Index { get; set; }
+    public AreaSizeEnum AreaSize { get; set; }
+    public Bitmap GFXBitmap { get; set; }
+    // ... other properties
+}
+```
+
+**Yaze:**
+```cpp
+class OverworldMap {
+  uint8_t index_;
+  AreaSizeEnum area_size_;
+  std::vector<uint8_t> bitmap_data_;
+  // ... other member variables
+};
+```
+
+### 3. Error Handling
+
+**ZScream:** Uses exceptions and try-catch blocks
+**Yaze:** Uses `absl::Status` return values and `RETURN_IF_ERROR` macros
+
+### 4. Graphics Processing
+
+**ZScream:** Uses .NET's `Bitmap` class and GDI+
+**Yaze:** Uses custom `gfx::Bitmap` class with OpenGL textures
+
+## Common Issues and Solutions
+
+### 1. Version Detection Issues
+
+**Problem:** ROM not recognized as ZSCustomOverworld
+**Solution:** Check that `OverworldCustomASMHasBeenApplied` is set correctly
+
+### 2. Palette Loading Errors
+
+**Problem:** Maps appear with wrong colors
+**Solution:** Verify palette group addresses and 0xFF fallback handling
+
+### 3. Graphics Not Loading
+
+**Problem:** Blank textures or missing graphics
+**Solution:** Check graphics buffer bounds and ProcessGraphicsBuffer implementation
+
+### 4. Overlay Issues
+
+**Problem:** Vanilla overlays not displaying
+**Solution:** 
+- Verify overlay pointer addresses and SNES-to-PC conversion
+- Ensure special area maps (0x80-0x9F) are properly loaded with correct graphics
+- Check that overlay ID mappings are correct (e.g., 0x009D → map 0x9D)
+- Verify that overlay preview shows the actual bitmap of the referenced special area map
+
+**Problem:** Overlay preview showing incorrect information
+**Solution:** Ensure overlay preview correctly maps overlay IDs to special area map indices and displays the appropriate bitmap from the special area maps (0x80-0x9F)
+
+### 5. Large Map Problems
+
+**Problem:** Large maps not rendering correctly
+**Solution:** Check parent-child relationships and large map detection logic
+
+### 6. Special Area Graphics Issues
+
+**Problem:** Special area maps (0x80-0x9F) showing blank or incorrect graphics
+**Solution:** 
+- Verify special area graphics loading in `LoadAreaInfo()`
+- Check that special cases for maps like 0x88, 0x93, 0x95, 0x96, 0x9C are handled correctly
+- Ensure proper sprite graphics table selection for v2 vs v3 ROMs
+- Verify that special area maps use the correct graphics from referenced LW/DW maps
+
+## Best Practices
+
+### 1. Version-Specific Code
+
+Always check the ASM version before accessing version-specific features:
+
+```cpp
+uint8_t asm_version = (*rom_)[OverworldCustomASMHasBeenApplied];
+if (asm_version >= 3) {
+    // v3 features
+} else if (asm_version == 0xFF) {
+    // Vanilla features
+}
+```
+
+### 2. Error Handling
+
+Use proper error handling for ROM operations:
+
+```cpp
+absl::Status LoadPalette() {
+    RETURN_IF_ERROR(LoadPaletteData());
+    RETURN_IF_ERROR(ProcessPalette());
+    return absl::OkStatus();
+}
+```
+
+### 3. Memory Management
+
+Be careful with memory management in C++:
+
+```cpp
+// Good: RAII and smart pointers
+std::vector<uint8_t> data;
+std::unique_ptr<OverworldMap> map;
+
+// Bad: Raw pointers without cleanup
+uint8_t* raw_data = new uint8_t[size];
+OverworldMap* map = new OverworldMap();
+```
+
+### 4. Thread Safety
+
+Both editors use threading for performance:
+
+```cpp
+// Yaze: Use std::async for parallel processing
+auto future = std::async(std::launch::async, [this](int map_index) {
+    RefreshChildMap(map_index);
+}, map_index);
+```
+
+## Conclusion
+
+Understanding the differences between ZScream and yaze implementations is crucial for maintaining compatibility and adding new features. Both editors follow similar patterns but use different approaches due to their respective languages and architectures.
+
+The key is to maintain the same ROM data structure understanding while adapting to each editor's specific implementation patterns.

+<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.
+
+<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.
+
+<2024-09-02 Mon>
