OKAY. Now, when I tested that rom (SFA2) on Mame, the sound seemed corrected. However, it only did so for
that rom!
I made the changes so that they're default for all roms, but they all have the same sound problem. Oddly enough, I came across a 400MB Mame pack I had on a disc lying around, which I transfered to my PC. Just to see if there'd be any differences. The Mame version in that pack was Mame32k 0.67, and
all roms I tested there had perfect audio. No issues at all, and I didn't even configure anything for it. Now, I made comparisons between settings of the Mame version I'm having problems with, and this older pack, but it still has those problems. So, one thing was solved, but another problem arises: I can play the Mame roms on this older Mame version with no audio issues. The new problem is that not all the roms from that 15gig Mame roms pack from Underground Gamer are compatible!!
Infact, of a little over 3000 roms, only a hand full were compatible! I noticed the Marvel Super Heroes rom for the newer Mame was 19MB, while the same game on the older Mame version was 20MB. That the hell?
I really hate all these different fucking versions crap.
