A built-in (or companion tool) feature for RetroArch that scans your cores and currently loaded games, detects which BIOS files are required but missing, and automatically suggests — or optionally fetches — the correct BIOS versions from a verified, curated BIOS pack repository.
BIOS (Basic Input/Output System) files are low-level firmware that contain the essential code from a video game console, enabling the emulator to "act" like that original hardware. These files are intimately tied to each console's hardware and are critical for accurate emulation. Without the correct BIOS, many emulator cores—particularly those for disc-based systems—cannot replicate the original hardware and games will fail to start.
If Neo Geo games fail, make sure the neogeo.zip file is in the same folder as your ROMs. Conclusion
BIOS packs usually arrive as compressed files ( .zip , .7z , or .rar ). retroarch bios pack

RetroArch is the ultimate frontend for retro gaming, but installing it is only half the battle. If you try to load games for the PlayStation, Sega Saturn, or Nintendo Game Boy Advance, you will often meet a black screen or a missing file error.
Some RetroArch cores use High-Level Emulation (HLE) to mimic a console's behavior without needing the original firmware. However, HLE is rarely perfect. It often causes game crashes, broken audio, or graphical glitches.
