Mega Man 3 Gameshark Codes (USA)

This page contains all of the Gameshark codes I have for Mega Man 3 (USA), a game for the Game Boy handheld console. If you are playing on a physical Game Boy/GBC then you'll need to purchase a physical Gameshark device to use the codes that you find on this page.

For those of you who are using an Emulator, you can normally input codes by going to the Cheats menu. Depending on the Emulator you use the process will be different, head over to my RetroArch, VisualBoy Advance (Depreciated), VisualBoy Advance-M, mGBA or Sameboy guides to learn how to use these codes with the Emulator of your choice.

If you don't see the code you are looking for on this page you should return to my Mega Man 3 Guides Index and choose a different section.
