I've tried both ps1 emus listed on this site, and neither of them can run ff7 where with one it is listed that it does, ha. The second has a unplayable framerate and crashes at the same spot. Does anyone know where I can find a better working ps1 emu?
If you've got a good PC you could emulate on that, otherwise you're not going to find better emulators on the Wii. WiiSX is still being worked on but there's no word on when it will be updated.
