I have an iMac G4 (specs in my signature) and thought it would be great to play Police Quest 3 via DOSBox on it. It ran great at default settings but when I changed the screen resolution to take up the entire full screen performance really suffered. Before doing this there were black bars all around the screen. Is this something to be expected or could a setting be incorrect. I tried this under Boxer and had the same results. The game runs great on my MBP but I was thinking I can use the G4 as an older gaming machine.
