Don't blame me if some codes don't work, people give them to me and I post them. The ones that I have tested say tested (this means they work). The ones that don't say tested doesn't mean that they don't work (maybe it does though) I might have just not tested them. Ask questions about all games in our message board. Please email me any new codes there are. Make sure when you email me that you send me the name of the game and the system the game uses. Thank you!!
