But neither had an impact. But I recall another game somewhere that had weird graphics artefacts because of some video tricks the game used. I don't remember the game, but I remember it was something about the color palette. Maybe something similar is happening here. I don't have VirtualBox installed, and I don't have much free time today to debug this. But I know others use VirtualBox so maybe you can try to reproduce it. Jim
