RetroBIOS¶
BIOS and firmware packs checked the way each platform checks them, with emulator source code as the deciding authority.
7,763 Files
12 Platforms
338 Emulators profiled
9.6 GB Total size
Of these files, 2,478 are console and computer system files, 2,746 arcade ROM sets (Arcade/), and 2,539 game and engine data (the RPG Maker/ and ScummVM/ trees).
Platforms¶
| Platform | Files | Checked by | Download | |
|---|---|---|---|---|

EmuDeck | 161 | MD5 | Pack |

RetroArch | 530 | exists | Pack |

RetroBat | 341 | MD5 | Pack |

RetroPie | 530 | exists | Pack |

RomM | 374 | MD5 | Pack |
Checked by is the test each platform runs on its own, replicated from its source code. RetroArch only looks for the filename; Batocera compares MD5 checksums, the fingerprint of a file's contents. How each mode works.
542 files are byte-identical to a dump catalogued by No-Intro, Redump, or TOSEC, and say so on their system page. What that means.
Where to extract
| Platform | Extract to |
|---|---|
| RetroArch | system/ |
| Batocera | /userdata/bios/ |
| BizHawk | Firmware/ |
| EmuDeck | ~/Emulation/bios/ |
| Lakka | /storage/system/ |
| MiSTer FPGA | /media/fat/games/ |
| ROCKNIX | /storage/roms/bios/ |
| Recalbox | /recalbox/share/bios/ |
| RetroBat | bios/ |
| RetroDECK | ~/retrodeck/ |
| RetroPie | ~/RetroPie/BIOS/ |
| RomM | bios/{platform_slug}/ |
The RetroDECK pack already carries its own bios/ folder, so it extracts one level above it. Every other pack extracts straight into the BIOS folder. Full instructions per setup.

Methodology
Platform lists are checked against emulator source code, file by file where a profile exists (how far that reaches). Documentation and metadata can drift from actual runtime behavior, so the source is the primary reference.
- Upstream emulator source -- what the original project loads (Dolphin, PCSX2, Mednafen...)
- Libretro core source -- the RetroArch port, which may adapt paths or add files
.infodeclarations -- metadata that platforms rely on, checked for accuracy
