By default, pSX Emulator will look for a file called biosSCPH1001.BIN which might be available on the web.Īfter the proper ROM file has been obtained, the application can load PlayStation CDs from your optical drive. The application is pretty basic but does allow you to play most available PS1 ROM files available, although a BIOS ROM file is required in order to get this application running.

Although a little bit outdated, pSX Emulator is a free application to run PlayStation 1 (PS1) games.
