Try that BIOS file unless your emulator specifically states otherwise. The one that works for most emulators is the American version, SCPH1001. There are three BIOS files in the downloads area that work for the different regions of PlayStations that were released: American, Japanese, and European. Without it, the emulator won’t work, but as soon as you have the BIOS, you’re good to go. Think of the PlayStation BIOS file as the activation key for the emulator.
You see, some other emulators come with the BIOS file included, but it doesn’t work that way for PlayStation emulators. If you’ve got your emulator and your ROM, though, you may be wondering why it’s not working. If you’re searching for an emulator, check out our recommendations for PlayStation emulators, and if you need ROMs, we also have a vast selection of PlayStation ROMs available.
Here is where you will find the BIOS file that is necessary to get your emulator working. You need three things to properly emulate a PlayStation on your computer or mobile device: an emulator, a PlayStation BIOS file, and a ROM.
