@stoney66 well - switched the roms and now they work. Centipede, Missile Command, Golden Tee 2 are all working now under AdvMame. Marble Madness is still unhappy, but I would assume that's still just a rom issue. I think this issue is likely resolved now. Thank you everyone for your help! @mahoneyt944 and @stoney66

Mi got everything working and games word smoothly. Question, trackball is inverted, do you know how to correct? When I take strokes they have very little power, is this a mouse sensitivity adjustment? Where do I find this?
