I have Vista and I'm trying to play the game through DosBox. Two problems. One the game is waaay too slow. I think I can fix that by altering cycles, though. However, the solution to the next problem continues to elude me. Much of the screen is black. I have to run my cursor back and forth to see anything. It's like I'm wiping the blackness away if that makes any sense. Anybody know what to do about that?
