After seeing a post in the SaASRT topic for some Saturn games I've never played, I wanted to go try them out. However, upon procuring some copies of these games, I mounted them appropriately and went to run the emulator. "Game disc unsuitable for this system." I downloaded the latest SSF version. Same error. Fiddled with the area code and BIOS. Same error. Converted the image types. Same error. Tried some of my current library of games. Same error. Burnt games to real discs. Same error. The only game I have working in my library for some unknown reason is NiGHTS, disc or image. Everything else has simply stopped working. Why would this be, and how can I fix it?
