So, I've been using NullDC 1.6 for a while now, and it's awesome. The first game that I obtained for it was Marvel Vs Capcom 2. The emulation was perfect. Now, all of a sudden, the sound in the game has been acting up, in a very strange way. In places (in the stages), the character's sound just randomly gets really quiet or dissapears alltogether. This never originally happened, which means I must of done something. I've tried replacing the bios and the emulator, but no change. What should I do?
