Oh, right. I feel kinda dumb right about now. I've used clrmamepro before, it's just been so long I forgot entirely about it. Oh well, now hopefully this thread will come up easily in future searches by noobs.
While we're on the subject of my lack of knowledge... Does clrmamepro (or any other program for that matter) have any option to sort roms that are dependent on, lets say, neogeo.zip? I want to make a romset that contains just MVS games and doing that the old fashioned way will take forever!
