Mega Man 4 - Weapon / Items Action Replay Codes (USA)

This page contains the Action Replay codes that I have available for Mega Man 4 (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 Mega Man 4 Guides Index and choose a different section.
