* Select BIOS: choose your own dumped BIOS file source. HLE is for the embedded open source BIOS,
which will change compatibility, so change between them if a game doesn't run at all with the commercial PSX BIOS.
Remember to put your own PSX BIOS file (Model SCPH1001 recommended) into the BIOS folder on your drive,
or you won't be able to select it here and use it. No, different BIOS models DO NOT CHANGE compatibility.
