This is the long-awaited sequel to JUMP. Started as a smaller collab inspired by the VIPs, it quickly spiralled out of control and became a true sequel. JUMP½ features even more of the wacky design and creativity JUMP is known for, on top of several new features and a significantly less brutal difficulty curve. Jump's storehouses and dragon coin reward system return, along with the level info menu, hint movies, and a retry system for the hardest levels. This hack also boasts a brand new ASM-heavy boss or two, new unlockable items, plenty of hidden puzzles and 3-UP moons, saving at any time on the overworld, and a few other neat features.

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.

Baron of Shell is an expert-difficulty Kaizo hack of Super Mario World focused on shell physics.

This hack represents the humble efforts of a foreigner to pay tribute to the Japanese hacks that thrilled and delighted him when he first took to romhacking. VIP and OTL; Kaizo and Kouhai; SUI and SIG--these and many others caught and held my imagination, and their influence is obvious in this hack (and I have tried to acknowledge my sources whenever possible). But, as always, the line between tribute and theft is a difficult one not to cross. It may be that the ghosts of old hacks and levels will resent the violence done to their mortal remnants. I am prepared for that.
