Mmmm. I've got somehow similar problems with almost every game I've tried emulating so far: Okami, MGS3, KH2.the bottom half of the screen isn't rendering as it should, like the middle and top.
But I thought it was because of the graphic card, since my x1950 IS pretty old
Can't confirm same glitches in FFX or DBZ, though. I don't own these games.
