How it works
Documentation and metadata can drift from what emulators actually load. To keep packs accurate, each file is checked against the emulator's source code.
- Read emulator source code - trace every file the code loads, its expected hash and size
- Cross-reference with platforms - match against what each platform declares
- Build packs - include baseline files plus what each platform's cores need
- Verify - run platform-native checks and emulator-level validation
