NOTICE: This ROM hack is still a work in progress.  Some features are incomplete, and bugs and crashes will be fixed soon.

Re-experience the tech-heavy action of the original Super Mario Kart with a haptic twist!

Take on the Mario Kart Grand Prix again with new rumble controls, with the controller responding to impacts between drivers, picking up coins, and more!  You may play with the rumble feature by plugging a SNES Rumble Controller into a real Super NES, or by setting up a virtual rumble controller in the latest version of Mesen.

Changelog

Version 0.3 – Added 2P checks for the title screen, kart select screen, cup select screen, and course select screen.  Added rumble effects for 1P gaining points on the results/standings screen, getting hit by the trophy, popping the cork off of the champagne, and the “CONGRATULATIONS” text on the podium screen.  Added a priority system for rumble effects.  More features and effects to come.

Version 0.2 – Added rumble effects for player disqualification, firing items, 1UP, all landings, all jumps, boosting, dizzy effect after spinning out, and colliding with more walls.  Improved rumble mixing between engine and effects.  More features and effects to come.

Version 0.1 – Added rumble effects for crashing into objects like pipes, other racers, and walls.  Tuned down the coin’s rumble strength.  Added a feature on the title screen where the player can toggle the engine’s rumble on and off.  More features and effects to come.

Notes:
Do NOT plug more than one SNES Rumble Controller into any Super NES.  Do not use SNES Rumble Controllers alongside or attached to a multi-tap.
The emulator Mesen will only rumble certain controllers plugged into the host system.  The author of this ROM hack used a Dual-Sense rumble controller with Mesen 2.1.1 on GNU Linux to test rumble functionality.
Do NOT redistribute, sell, trade, or exchange pre-patched ROMs through any means for cash, crypto, or other assets.  PIRACY IS A CRIME.
