What's included

BIOS, firmware, and system files for consoles from Atari to PlayStation 3. Each file is checked against the emulator's source code to match what the code actually loads at runtime.

  • 9 platforms supported with platform-specific verification
  • 328 emulators profiled from source (RetroArch cores + standalone)
  • 352 systems covered (NES, SNES, PlayStation, Saturn, Dreamcast, ...)
  • 6,748 files verified with MD5, SHA1, CRC32 checksums
  • 5251 MB total collection size

Supported systems

NES, SNES, Nintendo 64, GameCube, Wii, Game Boy, Game Boy Advance, Nintendo DS, Nintendo 3DS, Switch, PlayStation, PlayStation 2, PlayStation 3, PSP, PS Vita, Mega Drive, Saturn, Dreamcast, Game Gear, Master System, Neo Geo, Atari 2600, Atari 7800, Atari Lynx, Atari ST, MSX, PC Engine, TurboGrafx-16, ColecoVision, Intellivision, Commodore 64, Amiga, ZX Spectrum, Arcade (MAME), and 318+ more.

Build your own pack

Clone the repo and generate packs for any platform, emulator, or system:

# Full platform pack
python scripts/generate_pack.py --platform retroarch --output-dir dist/
python scripts/generate_pack.py --platform batocera --output-dir dist/

# Single emulator or system
python scripts/generate_pack.py --emulator dolphin
python scripts/generate_pack.py --system sony-playstation-2

# List available emulators and systems
python scripts/generate_pack.py --list-emulators
python scripts/generate_pack.py --list-systems

# Verify your BIOS collection
python scripts/verify.py --all
python scripts/verify.py --platform batocera
python scripts/verify.py --emulator flycast

Only dependency: Python 3 + pyyaml.

Documentation site

The documentation site provides:

  • Per-platform pages with file-by-file verification status and hashes
  • Per-emulator profiles with source code references for every file
  • Per-system pages showing which emulators and platforms cover each console
  • Gap analysis identifying missing files and undeclared core requirements
  • Cross-reference mapping files across 9 platforms and 328 emulators

How it works

Documentation and metadata can drift from what emulators actually load. To keep packs accurate, each file is checked against the emulator's source code.

  1. Read emulator source code - trace every file the code loads, its expected hash and size
  2. Cross-reference with platforms - match against what each platform declares
  3. Build packs - include baseline files plus what each platform's cores need
  4. Verify - run platform-native checks and emulator-level validation
