This patch for Mario Kart 64 (USA/NTSC) gives the CPUs in Grand Prix mode some of the same items a human can use. CPUs can finally fire shells, use multibananas, and triple mushrooms. Normally CPUs can only use single bananas, stars, ghosts, fake item boxes, single mushroom boosts, and lightning. They spawn the items all at the same time up to three times per lap and draw from their own item probability tables. CPUs never used shells, multi-bananas, triple mushrooms, or golden mushrooms. It turns out that a lot of this code never made it into the final game, and has remained hidden for over 20 years in the inside the game’s rom. Some of it it was never fully debugged or finished. This patch takes most of the unused CPU item spawning code that works and adds it back into the game with some custom assembly code. Please see the readme.txt file for more information.
