Here's a fun code I cooked up. The Mario Kart 64 (U) course randomizer. Play a Grand Prix Cup with four random courses, or VS mode with random courses. I know… it is 121 lines long. I don’t know a way to shorten it at the moment. If you find any bugs/issues, please let me know.
How it works is I mapped out where in RAM the grand prix course order is stored, and then used a bunch of random number generator queries to scramble the Mushroom Cup. The first line of code forces you to play the Mushroom Cup and the rest of it is random number generator queries to scramble the Mushroom Cup's course order.
You can also find this code and others, along with my notes, on my github wiki: Home * kfkaplan/nintendo64_hacking Wiki * GitHub
