Super Mario Bros + Duck Hunt - Enemy Modification Game Genie Codes (USA)

This page contains the Game Genie codes I have for Super Mario Bros + Duck Hunt (USA), a game for the original NES (Nintendo Entertainment System). If you're playing with an emulator you'll typically be able to put these codes into the program directly through a built in option. Any of you who are old school and playing on a physical console, you'll have to purchase a physical Game Genie cheat 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.

Note: The codes on this page also work for Super Mario Bros + Duck Hunt + World Class Track Meet.
