Kaizo Mario World 3, also known as Asshole Mario 3, is a hack created by T. Takemoto for his friend R. Kiba. It features extremely sadistic, unique and groundbreaking level design. The literal translation of "Kaizo Mario World" is "自作の改造マリオ（スーパーマリオワールド）を友人にプレイさせる", or in plain English, "Making my friend play through my Mario hack (Super Mario World)". Kaizo is a rough translation of the word "modify" or "change" in Japanese.
Hmm, this is the outdated version, version 3.0. Takemoto later made a version 3.1 which included a different maze, boss rush, and Yellow Switch Palace. Both of these versions will crash on console due to an outdated version of addmusic. Kaizoman and I fixed these patches and made a version 3.2 that works on console with patched music and English text. I would appreciate if an SMWC mod would contact me so I can get this updated version on here. Can do either 5-life or infinite lives version if need be, since infinite lives are acceptable in the speedrun. Thanks
