Hey, people... I just moved up to MAME 0.180 and I happen to have a few issues that I hope that someone can answer..

-I've tried to add CPS2 games onto MAME and it tells me that I need other ROM's and/or CHD files. Well, after reading that you need the Q Sound rom to get it to work... except it doesn't. Am I missing something here with Q Sound?
-There are also more then a few NEO GEO games that have just crashed before starting. What gives?
-Also, with Mortal Kombat 4... am I missing something for that game to work?
