Mega Man 4 - Weapon / Items Game Genie Codes (USA)
This page contains the Game Genie codes I have for Mega Man 4 (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.
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.
