I finally got to the final episode in Next Gen. Sonic and something wierd is going on with the stages, for instance everything will sometimes turn into a bluish-purple like color but for some reason it goes away sometimes when I hit this switch thing.  It's probably that scratch, but it really hasn't messed up the game the only thing it wouldn't load was Shadow's final cutscene and credits.  But as long as the game still works I'm ok, if it continues to screw up I'll probably have to buy a new copy.  So far the final episode is really sweet I hope I can beat it.
