# 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 1. **Profile emulators from source code** - read the code, document every file loaded, its hash, size, and validation 2. **Cross-reference with platforms** - each platform (RetroArch, Batocera, Recalbox...) declares what it needs 3. **Build packs** - for each platform, include the baseline files + what its cores actually require 4. **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. > **6,733** files | **5043.6 MB** | **8** platforms | **305** emulator profiles ## Download | Platform | Files | Verification | Pack | |----------|-------|-------------|------| | Batocera | 359 | md5 | [Download](../../releases/latest) | | EmuDeck | 161 | md5 | [Download](../../releases/latest) | | Lakka | 448 | existence | [Download](../../releases/latest) | | Recalbox | 346 | md5 | [Download](../../releases/latest) | | RetroArch | 448 | existence | [Download](../../releases/latest) | | RetroBat | 331 | md5 | [Download](../../releases/latest) | | RetroDECK | 2007 | md5 | [Download](../../releases/latest) | | RetroPie | 448 | existence | [Download](../../releases/latest) | ## Coverage | Platform | Coverage | Verified | Untested | Missing | |----------|----------|----------|----------|---------| | Batocera | 359/359 (100.0%) | 358 | 1 | 0 | | EmuDeck | 161/161 (100.0%) | 161 | 0 | 0 | | Lakka | 448/448 (100.0%) | 440 | 8 | 0 | | Recalbox | 346/346 (100.0%) | 341 | 5 | 0 | | RetroArch | 448/448 (100.0%) | 440 | 8 | 0 | | RetroBat | 331/331 (100.0%) | 330 | 1 | 0 | | RetroDECK | 2007/2007 (100.0%) | 2001 | 6 | 0 | | RetroPie | 448/448 (100.0%) | 440 | 8 | 0 | ## Documentation Full file listings, platform coverage, emulator profiles, and gap analysis: **[https://abdess.github.io/retrobios/](https://abdess.github.io/retrobios/)** ## Contributors ## Contributing See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines. ## License This repository provides BIOS files for personal backup and archival purposes. *Auto-generated on 2026-03-25T13:49:31Z*
