# RetroBIOS
|
|
|
|
Source-verified BIOS and firmware packs for retrogaming platforms.
|
|
|
|
Documentation and metadata can drift from what emulators actually load at runtime.
|
|
To keep packs accurate, each file here is checked against the emulator's source code:
|
|
what the code opens, what hashes it expects, what happens when a file is missing.
|
|
305 emulators profiled, 8 platforms cross-referenced,
|
|
6,733 files verified.
|
|
|
|
### How it works
|
|
|
|
1. **Read emulator source code** - identify every file the code loads, its expected hash and size
|
|
2. **Cross-reference with platforms** - match against what RetroArch, Batocera, Recalbox and others declare
|
|
3. **Build packs** - for each platform, include its baseline files plus what its cores need
|
|
4. **Verify** - run each platform's native checks (MD5, existence) and emulator-level validation (CRC32, size)
|
|
|
|
When a platform and an emulator disagree on a file, the discrepancy is reported.
|
|
When a variant in the repo satisfies both, it is preferred automatically.
