How to Find the ePSXe BIOS


A BIOS system is used to properly boot up a computer using its existing hardware. In the case of the Sony PlayStation (PSX), the BIOS does roughly the same thing. When you turn on the PlayStation, the game console boots into the BIOS menu, which allows you to change the date, time and the option to boot up a game disc. If you have a game disc inserted when the console is powered on, the system does not show the BIOS menu and boots directly to the game. The PlayStation emulator that allows you to play your PlayStation games on your computer is called ePSXe. Like the console itself, ePSXe needs a BIOS system in order to run.

  • Click "Start" and then "Computer."

  • Click the "C:" drive on the list that is displayed. Double-click the "Program Files" folder to open the list of installed programs. Open the "ePSXe" folder.

  • Locate and open the "BIOS" folder near the top of the directory that you just entered. The list of BIOS files will be inside this folder.

  • Locate the "SCPH1001.BIN" BIOS file if you are running the PlayStation NTSC games, which means they are from North America. Locate the "SCPH7502.BIN" BIOS file if you are running European games.
