For some reason mk2 will not detect my gravis ultrasound no matter what irq, dma, or port combination I try. I tried disabling soundblaster as well and that didn't help either. The real confusing part is that mortal kombat 1, on the very same cd, will work with gravis ultrasound just fine. Why would one game work fine and the other one not? I believe my ultrasound folder is configured correctly because it also works in another game I tried, Turrican 2.
