Hey whats up, Ive been trying to get the playstation emulator to work but every time I try to play a game it shows me this, anyone know how to resolve this/where to get BIOS files To run this core you need the following: PlayStation SCPH-5500 (v3.0 Japan) BIOS 'scph5500.bin' PlayStation SCPH-5501 (v3.0 America) BIOS 'scph5501. ago That's a US region bios file for ps1, it's the set of files that tells the system what to do, and you will not be able to run ps1 games without one.
