 # RetroBIOS

-Source-verified BIOS and firmware packs for retrogaming platforms.
+Complete BIOS and firmware packs for RetroArch, Batocera, Recalbox, Lakka, RetroPie, EmuDeck, RetroBat, RetroDECK, and RomM.

-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.
-306 emulators profiled, 8 platforms cross-referenced,
-6,733 files verified.
+**6,748** verified files across **294** systems, ready to extract into your emulator's BIOS directory.

-### How it works
+## Download BIOS packs

-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)
+Pick your platform, download the ZIP, extract to the BIOS path.

-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.

+Source: https://github.com/rommapp/romm
+Format: JSON fixture mapping "slug:filename" to {size, crc, md5, sha1}
+Hash: SHA1 primary (all four hashes available per entry)
+
+RomM stores known BIOS hashes in known_bios_files.json. At startup, the
+fixture is loaded into Redis. When scanning or uploading firmware, RomM
+verifies: file size must match AND at least one hash (MD5, SHA1, CRC32)
+must match (firmware.py:verify_file_hashes).
+
+RomM hashes files as opaque blobs (no ZIP content inspection). Arcade
+BIOS ZIPs are matched by their container hash, which varies by MAME
+version and ZIP tool. This is a known limitation (rommapp/romm#2888).
+
+Folder structure: {library}/bios/{platform_slug}/{filename} (flat).
+Slugs are IGDB-style platform identifiers.
