I bought a StarTropics cart recently on Craigslist. When I started a new game file, everything was performing as it should be. I listened to Chief Coralcola's warning and received the Island Yo-yo. However, the person who is guarding the entrance to the tunnel still says to get away from there, and that he doesn't know me.
Is this a problem with the cart itself, or does my NES need to be cleaned?
