Mario Kart 64 - Stomper Mod

Hack of Mario Kart 64


A Mario Kart 64 modification, which replaces GP mode with a custom game mode called “Stomper Mode”.

You’re not racing laps, but are tasked to drive over each CPU-driver, in order to stomp and remove them from the “race”.

When all enemies are removed, the game advances to the next course in the cup. In 2-Player mode, each player gets their own point counter, so try to get the most points!

Each cc-class has a different difficulty, so enemies get smaller and therefore more difficult to stomp. They also have a higher max speed, the smaller they are. The item table is limited to Mushrooms, Green Shells, Bananas and Fake Itemboxes.


This game needs an Expansion Pak. Your emulator also needs to be set to support the memory extension. Set it to 8 MB memory. The way to do this varies for each emulator, so please look it up online, if you are unsure how to.

How to play:

  • 1. Choose either 1 or 2 player GP mode on the cc-class you want
  • 2. Proceed to the race
  • 3. Drive over enemy racers in order to finish the course

Known issues:

  • CPU drivers sometimes drive too far off the road when near them. They will snap back to the road, when they’re off-screen.
  • If a CPU driver gets hit by certain course hazards (trees, nuts, penguins, thwomps) you can score a point by driving over them, when they’re already flattened.

Changelog 1.1

  • Fixed a console only crash on Rainbow Road

Good fun, could use some features

Great little minigame to kill some time. It’s essentially everything it says it is and plays great! A few suggestions though:

An optional time limit: Just to spice up the game and give a reason for points. As it is right now you’ll always finish at 28 points (7 per ‘race’) so the total feels a little pointless.

Enemies using items: Same idea to just spice the game up. Even on 150CC it’s not overly difficult to squish everyone.

Remove some hazards: In stages like Kalimari Desert, hazards work more to the players advantage. When the train blocks off the track, the CPUs will come to their regular halt and be easy targets

Other than that, this was really fun! Great work to those involved.

Version 1.1 Recommended - Yes
