Super Mario Bros + Duck Hunt - Super Mario Bros. Action Replay Codes (USA)

This page contains the Action Replay codes that I have available for Super Mario Bros + Duck Hunt (USA), a game for the original NES (Nintendo Entertainment System). If you're playing on an emulator, you'll typically be able to put these codes into the program through a built in option. Anyone who is really old school and playing on a physical console will have to purchase a physical Action Replay device to use these codes.

When it comes to emulation for the NES you have 3 good options to choose from. You can do RetroArch, Nestopia or MesenCE, follow the links provided to learn more about how to use the codes you find on this page on the Emulator of your choice. If you don't see the code you want on this page, I recommend you return to my Super Mario Bros + Duck Hunt Guides Index and choose a different section.
