Takua 64 (Bionicle64) is a major SM64 ROM Hack created by Superstupidy. It is a total conversion mod of the world of Bionicle, including environment and level design inspired by games like Metroid Prime, Tomb Raider, and the majority of Bionicle games. With 99 "Toa Stones" to find and collect, this hack features 12 levels, each with multiple areas to explore and challenges to overcome. Most of the followed characters are replaced/designed based on Bionicle's world while still keeping Mario 64's gimmick aspect and gameplay style.

Prior to the creator, quoting: "Takua 64 is aimed at pleasing (hopefully) Bionicle fans with little to no SM64 experience as well as SM64 veterans with its difficulty." In terms of difficulty, this hack demands a few SM64 speedrunning techniques such as slidekicks and BLJs in order to complete.

The hack was Initially released without a music soundtrack (mostly for realistic ambience), then it was re-released with a music update not linked to the Bionicle games and the addition of Parallel Camera.
