Apparantly from what i've heard :
Japan
the audio problem effects any game using midway's dcs (mk2 and 3 as well as wwf wrestlemania) and mame team still has yet to fix this problem as far as i read.
Midway treasures 2 was awsome when all I knew about was Mks, but primal rage too?! Its a must buy, too bad they didnt make them xbox live versions of Mk3U and Primal Rage...
) the games runs perfect with very lil sound issues.
thinking about mame 61, it just hit me that the last mame-x is based off that and it plays mk2 better then mame ox since it has a hack for dcs sound on the midway games that had dcs. unfortunatly none of the mk3's or wwf wrestlemaina doen't loadup on mame-x unless you got the memory update (if mame-x supports the extra memory that is)
