Sorry to jump in on a post that is marked "Solved" but I have an on going issue that is driving me mad. I have 2 MAME system running Hyperspin but I want to upgrade to Arcade Maximus as it has all the filters etc and I have kids playing these systems. The problem I am having is that I can get all the games working and all flowing nicely on my laptop, as soon as I transfer ever onto the MAME's I can get everything to run beautifully (SEGA gen, PSX, N64 and so on) but when I go into MAME all the games are there, I can move around using controllers (IPAC2 setup) but I cannot execute the game launch, its just "Boing!" (best way to describe it) have tried downloading an ipac2.cfg and all the keys work but no matter what I do the games wont launch. I have spent MANY hours in the last week searching for the answer but am at a loss. It might be the simpliest of things but I have burnt all logic on this matter this week so am looking for a nudge in the right direction. My thinking was that it was a conflict with the IPAC2 but like I meantion it works in the menu just wont exe the game.
Any assistance greatly appreciated as I have 3 more to build yet.
