	Well, I found the problem. As I suspected it was caused by the
fact that a 3B20 has unsigned characters.
	In display.c, near the function moveplayer(), there are two
arrays, diroffx[] and diroffy[], that contain values to move the player.
They both have '-1's in them and were declared as char arrays. Hence,
the -1's became 255's. Changing 'char' to 'short' solved the problem.
