+# Suyu Bug Fixes Plan
+
+## 1. Game-specific issues
+
+### Approach:
+- Analyze logs and crash reports for the affected games (e.g., Echoes of Wisdom, Tears of the Kingdom, Shin Megami Tensei V).
+- Identify common patterns or specific hardware/API calls causing issues.
+- Implement game-specific workarounds if necessary.
+
+### TODO:
+- [ ] Review game-specific issues in the issue tracker
+- [ ] Analyze logs and crash reports
+- [ ] Implement fixes for each game
+- [ ] Test fixes thoroughly
+
+## 2. Crashes
+
+### Approach:
+- Implement better error handling and logging throughout the codebase.
+- Add more robust null checks and boundary checks.
+- Review and optimize memory management.
+
+### TODO:
+- [ ] Implement a centralized error handling system
+- [ ] Add more detailed logging for crash-prone areas
+- [ ] Review and improve memory management in core emulation components
+
+## 3. Shader caching and performance issues
+
+### Approach:
+- Optimize shader compilation process.
+- Implement background shader compilation to reduce stuttering.
+- Review and optimize the caching mechanism.
+
+### TODO:
+- [ ] Profile shader compilation and identify bottlenecks
+- [ ] Implement asynchronous shader compilation
+- [ ] Optimize shader cache storage and retrieval
+- [ ] Implement shader pre-caching for known games
+
+## 4. Missing features
+
+### Approach:
+- Prioritize missing features based on user demand and technical feasibility.
+- Implement support for additional file formats (NSZ, XCZ).
+- Add custom save data folder selection.
+
+### TODO:
+- [ ] Implement NSZ and XCZ file format support
+- [ ] Add UI option for custom save data folder selection
+- [ ] Update relevant documentation
+
+## 5. Add-ons and mods issues
+
+### Approach:
+- Review the current implementation of add-ons and mods support.
+- Implement a more robust system for managing and applying mods.
+- Improve compatibility checks for mods.
+
+### TODO:
+- [ ] Review and refactor the current mod system
+- [ ] Implement better mod management UI
+- [ ] Add compatibility checks for mods
+- [ ] Improve documentation for mod creators
+
+## 6. General optimization
+
+### Approach:
+- Profile the emulator to identify performance bottlenecks.
+- Optimize core emulation components.
+- Implement multi-threading where appropriate.
+
+### TODO:
+- [ ] Conduct thorough profiling of the emulator
+- [ ] Optimize CPU-intensive operations
+- [ ] Implement or improve multi-threading in suitable components
+- [ ] Review and optimize memory usage
+
+## Testing and Quality Assurance
+
+- Implement a comprehensive test suite for core emulation components.
+- Set up continuous integration to run tests automatically.
+- Establish a structured QA process for testing game compatibility and performance.
+
+Remember to update the relevant documentation and changelog after implementing these fixes. Prioritize the issues based on their impact on user experience and the number of affected users.
