Wiimms Mario Kart Fun 2021-09

Wiimms Mario Kart Fun 2021-09 is a custom track distribution created by Wiimm. It was released on 2021-09-11, nine months after the previous version. The nine month gap is the longest in series history, brought about by the extended workload placed on the author by Wiimmfi, LE-CODE, and Wiimms SZS Tools.
