Heavy Barrel Action Replay Codes (USA)
This page contains the Action Replay codes that I have available for Heavy Barrel (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.
If you don't see the code you want on this page, I recommend you return to my Heavy Barrel Guides Index and choose a different section.
