How do you fix a broken GameShark?

To fix a broken GameShark, first check the connections and ensure it’s properly seated in the console. Clean the cartridge contacts with isopropyl alcohol and a cotton swab to remove any dirt or corrosion. If it still doesn't work, consider replacing the battery if it's a model that uses one, as a dead battery can cause issues. Lastly, consult online forums for specific troubleshooting tips or common fixes related to your GameShark model.
