Ok, i dont know the noumbers of these mappers, but ill tell you the rom names, and you see what you can do.
Othello HES Version
Rad Racer 2, Mach Rider (road is alittle Glitchy)
Mapper 182,64,90 (some Unl games have these)
One more thing.. When i go to load another rom while one is still playing (without closing emulation), it takes a little too long to go to the next rom. I dont know, but the older versions didnt do this.
