Yes it did but they don't make GP2Xs anymore and most people would prefer to make SNES or GBA games.
And Hblade it sounds like you have already modified your copy of Game Editor to Create GBA and SNES games, and your just suggesting Makslane for it to be a built in feature. I am very doubtful that he will add that feature but if you really have modified a copy of Game Editor then can you please tell me how to make my copy like yours?
