Dr. Mario 64 Gameshark Codes (USA)
This page contains the Gameshark codes that I have for Dr. Mario 64, a game for the Nintendo 64. If you are playing on a physical N64 console then you will need to purchase a physical Gameshark or Xploder device to use the codes you find on this page and website. From what I have read and seen both of these cheat devices have cross compatibility.
For those of you out there using an Emulator, using cheats is typically straight forward. There's normally a toolbar at the top of your Emulator that will lead you to the cheats window. I have guides to help you setup cheats with RetroArch, Mupen/RMG and Project 64; follow the links provided to the Emulator of your choice.
If you don't see the cheats you're looking for on this page I recommend you return to my Dr. Mario 64 Guides and Walkthroughs page and choose a different section.
