Yeah, I only have the Smash TV MAME ROM loaded cause I just bought the cabinet. Of course. And only verion 5 until my version 8 ROMs arrive. Oops. I mean until I find a machine with version 8 ROMS.
But as for MJ Moonwalker, a good friend of mine's kid plays it all the time. He loves it! Figured it would be a kid that's only 8 now, huh? I play it (on someone else's cab since I only have Smash TV on mine, remember) every now and then. The biggest problem I've found with MAME is that on someone else's cab there are so damn many things to choose from that it exacerbates the instant gratification syndrome.
You know I'm BAD.
