|
|
- Save/discard workflow preventing ROM changes until explicit user action
|
|
|

|
- Implemented Windows COM-based file dialog fallback for minimal builds
|
|
- Consistent cross-platform behavior and stack resources
|
|
|
|
### Emulator: Audio System Infrastructure
|
|
|
|
**Audio Backend Abstraction:**
|
|
- **IAudioBackend Interface**: Clean abstraction layer for audio implementations, enabling easy migration between SDL2, SDL3, and custom backends
|
|
- **SDL2AudioBackend**: Complete implementation with volume control, status queries, and smart buffer management (2-6 frames)
|
|
- **AudioBackendFactory**: Factory pattern for creating backends with minimal coupling
|
|
- **Benefits**: Future-proof audio system, easy to add platform-native backends (CoreAudio, WASAPI, PulseAudio)
|
|
|
|
**APU Debugging System:**
|
|
- **ApuHandshakeTracker**: Monitors CPU-SPC700 communication in real-time
|
|
- **Phase Tracking**: Tracks handshake progression (RESET → IPL_BOOT → WAITING_BBAA → HANDSHAKE_CC → TRANSFER_ACTIVE → RUNNING)
|
|
- **Port Activity Monitor**: Records last 1000 port write events with PC addresses
|
|
- **Visual Debugger UI**: Real-time phase display, port activity log, transfer progress bars, force handshake testing
|
|
- **Integration**: Connected to both CPU (Snes::WriteBBus) and SPC700 (Apu::Write) port operations
|
|
|
|
**Music Editor Integration:**
|
|
- **Live Playback**: `PlaySong(int song_id)` triggers songs via $7E012C memory write
|
|
- **Volume Control**: `SetVolume(float)` controls backend volume at abstraction layer
|
|
- **Playback Controls**: Stop/pause/resume functionality ready for UI integration
|
|
|
|
**Documentation:**
|
|
- Created comprehensive audio system guides covering IPL ROM protocol, handshake debugging, and testing procedures
|
|
|
|
### 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:**
|

- `/permissive-` - Standards conformance mode
|
|
- `/wd4267 /wd4244` - Suppress harmless conversion warnings
|
|

|
|
- **Progressive Loading**: Implemented priority-based progressive loading in `gfx::Arena` to prevent UI freezes
|
|

|
|
|

|
|
- Heap-based allocation for large data structures instead of stack
|
|
- Streaming/chunked loading for large ROM assets
