Hello. You have what may be a broken 72 Pin Connector. You May want to get a new one or it may be dirty so just clean it. The Game may be dirty too. Cut off the green part of a sponge or get scrub pads from the store too clean your pins. If it does not work, Open your cartridge and clean the pins well with a small ammount of counter top cleaner. brish it on and then take a towl and wipe the cleaner off. Then put the case back on. Please only do this with the game.
