New Super Mario Bros Action Replay Codes (USA)
This page contains the Action Replay codes I have for New Super Mario Bros, a game on the NDS. If you are using a physical NDS console then you will need to purchase a physical Action Replay device in order to make use of the codes on this page and website.
For those of you out there who are using an emulator such as Desmume, there is usually a tab at the top of the emulator that will lead you to the section where you can input these codes. If you'd like more information on How to Setup Codes on Desmume NDS Emulator please follow the link provided.
If you don't see the code you're looking for on this page I recommend you return to my New Super Mario Bros Guides and Walkthroughs and choose a different section.
