PSX games aren't seen by the emulator when using BIOS
Migrated from https://bugzilla.gnome.org/show_bug.cgi?id=783135
Up until now, I was using PCSX's HLE BIOS, and overall things worked.
A few games weren't well supported though, so I decided to try out the "real" BIOS.
I downloaded all 3 .bin files, and verified their MD5 are the same as in the .libretro file.
I tried those BIOS files one after the other, putting them in the right place, then starting Games.
With each one I got the same result: the emulator gives me the "Please insert PlayStaion CD-ROM" screen (different versions of it, depending on the used BIOS), as if it didn't see the game.
I get this for all the PSX games I have here.
However, for those that are multi-disc, I tried something: when I'm on the "Please insert PlayStation CD-ROM" screen, if I switched disks then the emulator starts the game just fine.
