[collab project] collab kart

so after like 4 months of not playing, i just want to say that im back for a bit, which brings me to an idea of a collab multicup. due to the criticism of the last multicup i made, retro rewind, i wanted to think of something more unique. Collab kart (i need a better name) will be like a standard collab multicup, but like a standard mario kart with 4 nitro cups, and 4 retro cups . another complaint was the track quality. looking back, i cant believe i let crap into the other multicup. so i will try to be more strict on the quality.
