Insane Kart Wii is the most massive and chaotic modpack ever created for Mario Kart Wii (released in 2008 on Wii). Formerly known as the Ultimate Hack Pack, it's a Custom Track Distribution (CTD) that transforms the game into an "infinite" experience with nearly 5,000 custom tracks, hundreds of battle arenas, custom characters, wacky modes, and a plethora of options.

With the goal of compiling all the best custom tracks from the community, this pack includes no fewer than 5,000 tracks, 200 arenas, 64 missions, and new custom characters.
