Open the emulator, don't select a game, go to: "options", "configure graphics plugin" and then go to the "directX" tab, change the combiner type, click ok and run the game. If the combiner you selected doesn't work try another and you'll eventualy find the right one.
Lol sorry for double post..but the graphics and all that are awsome, the problem is the sound..i dont here the base of the music and such. And when I try to go in the Audio plugin it doesn't pop up. I possibly don't have one in there but i will check..
As long as you are using 1964 + Rice's Video, most sound plugins work fine. At least for me they do. Only in PJ64 does the sound mess up when using Rice's Video for some bizarre reason.
