Kaizo Mario World, also known as Asshole Mario, is a hack created by T. Takemoto for his friend R. Kiba. It features extremely sadistic, unique and groundbreaking level design. This is also the hack that started it all, since the kaizo genre wasn't existent beforehand. 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. However, due to this Hack, Kaizo has now become a catch-all term for extreme and possibly "unfair" difficulty hacks.

Mario is captured and sent to the jail factory, and has to find a way out. Try not to explode!

Extremely easy and forgiving kaizo hack. Accessible to beginners, and hopefully nice for the average player to breeze through. Mario has Reznorvations for dinner at the Castle, and you must help him get there. I hope you have fun.

For the past seven years, SMW Central has held a vanilla level design contest every spring. “Vanilla level design” refers to using only Lunar Magic to create your level - that is, no custom blocks, no custom sprites, and no custom code of any sort. They eventually began allowing people to use custom music, but this is not factored into their score. Once they finished designing their level, they would submit an IPS file, it would get judged + ranked, and that would be the end of it. This year, however, S.N.N. decided to assign resources (secondary exits, Map16 slots, etc) to users with the intention of putting all of their levels into a ROM and essentially creating a full hack out of it. The hack features 82 submitted entries and 4 switch palaces, which makes a grand total of 86 levels for you to beat. All of the levels are open from the start - you can play them in any order you’d like. To help you keep track of your progress, the game autosaves on the world map and beating a level will give you an “M” in the top right corner of the overworld. As a disclaimer, the levels are organized on the overworld by theme, and not by ranking. This means that the quality of the levels might fluctuate dramatically from one to the next (e.g. having a 70th place entry directly before a 12th place entry). The bottom 8 and top 8 each have their own world, however, so it’s easy to distinguish them from the rest.
