Only about half the games I play acturally work. I know the roms work because my friend was using them on his computer. My current computer is a 3.0ghz 9100 Radeon and 448 ram so i dont believe my computer specs are a problem. I have downloaded alot of the video plug ins and tested some of them. Downloading the rice plug in fixed alot of the visual problems i had been having.. but still alot of the games dont work. At the bottom of 1964 it showcases % on visual audio etc which seem to be in the 4-10% range on each.. than they just drop to 0% and the game doesnt go any further.
