Hi I'm kinda new to emulators. My friend gave me a DVD containing a MAME emulator and 4 gigs of rom. I recently upgraded from MAME32 v0.58 to MAME v0.105u1. Alot of the roms that was working with the v0.58 does not work with the v0.105u1. When I try to run the roms like Gauntlet 1 or 2 I get an error stating some files are missing with the v0.105u1 but the v.0.58 there are no errors. Any ideas why is this happening?
