RetroBIOS

Source-verified BIOS and firmware packs for retrogaming platforms.

Every file in this collection is traced to its ground truth: the emulator's source code. Not .info files, not documentation, not community wikis - the actual code that loads the file. 305 emulators profiled from source, 8 platforms cross-referenced, 6,733 files verified.

How it works

Profile emulators from source code - read the code, document every file loaded, its hash, size, and validation
Cross-reference with platforms - each platform (RetroArch, Batocera, Recalbox...) declares what it needs
Build packs - for each platform, include the baseline files + what its cores actually require
Verify everything - platform-native verification (MD5, existence) + emulator-level validation (CRC32, SHA256, size)

When a platform and an emulator disagree on a file, we detect it. When a better variant exists in the repo, we use it.
