A curated, source-verified collection of BIOS and firmware files for retro game emulators, packaged per platform (RetroArch, Batocera, RetroPie, EmuDeck, MiSTer FPGA, and others). Each pack replicates the exact file checks each emulator performs, verified against emulator source code and checksums.
Use cases
- set up BIOS files for RetroArch without hunting them down
- install complete BIOS pack for Batocera or Recalbox
- fix missing BIOS errors in EmuDeck or RetroDECK
- download verified firmware for MiSTer FPGA
- populate BIOS folder for a retro handheld SD card
- verify emulator BIOS files against checksums
- bulk-install BIOS files for BizHawk
When to choose
- you need complete, checksum-verified BIOS sets for one or more retro emulation platforms
- you want a one-command installer that auto-detects your platform and only downloads missing files
- you want files validated against emulator source code rather than forum folklore
When to avoid
- you need BIOS files for platforms not covered by the twelve supported packs
- you require a permissive open-source license - the repo's license is non-standard and the underlying BIOS files are copyrighted dumps
- you only need one or two BIOS files and can source them yourself
