If you have a game tip you want to submit, by all means please do so! If you have a tip for a system I don't have listed, check the "Multiple/Other" box and make note in the tip field what system it's for.
Please, no Game Shark tips, or tips for any other such devices. Since these are made by 3rd parties and can possibly damage your system, I do not wish to encourage their use.
If you notice any tips that don't work or are listed incorrectly, email me and I will correct them. If you have problems with email, use my web form on the contacts page.
