Frequently Asked Questions

What is a PlayStation BIOS?
A BIOS (Basic Input/Output System) is the core system software found in every PlayStation console. Emulators use it to replicate console behavior accurately—boot animations, game loading, and memory card handling all rely on the BIOS.
Yes. Most PlayStation emulators (especially PS1 and PS2) require a BIOS file to function properly. RPCS3, the PS3 emulator, uses official system firmware instead.
Only if you dump it from your own console. BIOS files are copyrighted; however, the PS3 firmware (PS3UPDAT.PUP) is legally distributed by Sony.
PS1: DuckStation, ePSXe, Mednafen PS2: PCSX2, AetherSX2 (Android) PS3: RPCS3 (uses Sony firmware)
Each emulator has a designated “BIOS” or “Firmware” folder (configurable in settings). Our setup guides detail exact paths for every platform.
Ensure the BIOS file isn’t zipped, placed in the correct directory, and matches your emulator’s region settings.
