Technical background The PS1 BIOS contains low-level routines that games expect from PlayStation hardware. Some games rely on specific BIOS behaviors; others can run using high-level emulation without the original BIOS. RetroArch uses cores (libretro cores) such as Beetle PSX (HW/mednafen-based), PCSX ReARMed, or FPse cores that may accept or require a BIOS file for full compatibility or to enable certain features (BIOS boot screens, accurate CD audio handling, region-specific behavior).

If you own a PSP with firmware version 6.60, you can extract the BIOS data using specialized tools. Alternatively, those who own a physical PlayStation 1 console can dump its original BIOS using devices like a "game saver" or through a modded console.
