What Is a PS1 BIOS File?

The PlayStation 1 BIOS (Basic Input/Output System) is the core firmware embedded in every original PS1 console. When you power on the PlayStation, the BIOS runs first — it initializes the hardware, checks connected components, and then boots the game disc.

To play PS1 games on an emulator (like ePSXe, RetroArch, or DuckStation), you need the BIOS file. Without it, the emulator cannot replicate the original PlayStation hardware and games simply will not load.

PS1 BIOS files are 512 KB .BIN files. Each region — USA (NTSC-U), Japan (NTSC-J), and Europe (PAL) — has its own BIOS version. For most games and emulators, SCPH1001.BIN (USA v2.2) is the go-to choice.

Whether you're playing Crash Bandicoot, Final Fantasy VII, Tekken 3, Metal Gear Solid, or Resident Evil 2 — all PS1 games work with any regional BIOS. Use the USA BIOS (SCPH1001.BIN) as the default, and switch to the regional version only if a specific game requires it.
