I tried to install Jazz1 on my friend's computer, but it has Win XP. I managed to Tppatch it, and the game runs, but the sound runs very slowly, and it jumps. I'm not sure if XP has anything to do with it, or if it's his sound card. I checked the audio properteries, and he had a sound card that I have never heard of before. it was called "SIS".. it seemed to be compatible with the sound blaster settings on Jazz1, but I'd get that sound problem. any ideas of how to make it work with this card?
