ok, good news: the game no longer crashes when it goes to the level select map, but bad news: 2 player doesn't occur at all, no 2nd screen at teh bottom, no 2nd player movement, so i guess that line disabled all the 2 player script. also, in order to stop the screen from jittering, you need to change the scroll rates to like 30x30 (can be higher, but these work for all intensive purposes).
