- Please click "Download" to download a .txt file to your computer with the different codes.
- This is not a list of every single cheat code ever made, but is a list and direct import of most from: Codes: Mario Kart Wii [RMCJ01] (NTSC-JP) at GeckoCodes.org - WiiRD Code Database
- While this is a list of different cheat codes, certain cheat codes that give you an advantage are not condoned or allowed by 4DR or on Wiimmfi. They are only here as a resource or for friend rooms/offline use. Please refer to the following document for what is allowed on Wiimmfi: Wiimmfi Rule Booklet
- Last updated: May 26, 2020. I do not plan to regularly update this resource and don't expect there to be many updates anyway as the hacking scene for Mario Kart Wii is quite dead, but I may check occasionally and update as needed.
