Yes I know these things suck by nature, but my little nephew got one and we're trying to get it to play cartrdiges and it just won't. Is there some trick to making it recognize that a cart is inserted. I tried 10 different cartridges (all clean and in great shape) and it just goes to the main menu every time where it lets you select the preloaded games. It doesn't even seem to recognize that a cart is plugged in.... Is this thing just busted? Please help.
