The creator of this romhack, MrComit, managed to take classic Mario Party levels such as Yoshi's Tropical Island or DK's Jungle Adventure, and make them into their own adventure, complete with mini-games and 70 Stars to collect. Version 1.02 is available to download in the video description as a .bps patch, which can be applied to a copy of Super Mario 64.
