Mario Kart 64 - Top Speed Modifier Action Replay Codes (USA)

This page contains the Action Replay codes that I have for Mario Kart 64 (USA), a game for the Nintendo 64. If you are playing on a physical N64 console then you will need to purchase a physical Action Replay 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 Mario Kart 64 Action Replay Codes page and choose a different section.

Note: When you use a Mushroom, you are propelled to just beyond your maximum speed. So don't set it too high or using a Mushroom might freeze the game.

 

(Player 1) Max Speed Modifier

810F6BA4 ????
810F6BA6 ????

 

(Player 2) Max Speed Modifier

810F797C ????
810F797E ????

Replace the ???? and ???? above with the modifier you'd like to use from below - or make your own!

439B 0000 - Default for Time Trials
4391 0000 - Default for 50CC
43A0 0000 - Default for 150CC

This actually seems to effect all human players. When I did versus all 4 players could go fast, but when I did Grand Prix on the human player(s) could go fast.
