Ok, my Star Ocean 2 first disc got damaged pretty bad, so I tried to make a backup dy downloading the ISO and making a backup with CloneCD. The ISO has the ccd, img and sub files, so I know it was ripped with CloneCD, and the writing process worked fine, but when it came to actually playing the game it doesn't work on my modded PSX!
I also tried it on my unmodded PSX, PS2, and ePSXe, with the following results:
ePSXe - Works just fine
Modded PSX - The game doesn't load. It just goes to the CD player/Memory Card screen. The disc doesn't spin.
Unmodded PSX - Shows the error message about wanting an actual PSX game disc as it should.
PS2 (Unmodded) - Doesn't load the disc, just goes to the browser screen, with "loading disc" written.
I know its not a problem with the modded PSX itself, because it plays other backups just fine.
Does anyone have any idea whats going on?
