Values are \(lqautodetect\(rq, \(lqdefault\(rq, \(lqvga\(rq, or \(lqvesa\(rq.
Setting \(lqvesa\(rq will cause the game to display tiles, using the full

Setting \(lqvga\(rq will cause the game to display tiles, fixed at 640x480
in 16 colors, a mode that is compatible with all VGA hardware. Third party
tilesets will probably not work.
Setting \(lqautodetect\(rq attempts \(lqvesa\(rq, then \(lqvga\(rq, and
finally sets \(lqdefault\(rq if neither of those modes works.
