Sonic the Hedgehog (also know as Sonic 4) is an unlicensed game for the SNES by Peruvian scene organization Twin Eagles Group. It is, actually, a hack of Speedy Gonzales: Los Gatos Bandidos.

This game is a hack of Street Fighter II: Champion Edition, notable for modifying many gameplay aspects, the most noticeable being the ability to transform into other characters and being able to pull off special moves in midair. Some of the special moves were modified, such as the Hadokens, which can either home in on the opponent or travel extremely fast, as well as 7 different characters being able to execute them as opposed to just Ryu and Ken. Zangief moves noticeably faster in this game, and E. Honda can pull off Hadokens when performing his Hyakuretsu Harite. The graphics and music are identical to those in the original game aside from the title's logo, which is now rainbow-coloured, which is where this hack gets its name from. Although there are many different revisions of this hack readily dumped and emulated, several versions are still left undumped. The rampant craziness with these hacks and the popularity of arcade distributors putting these hacks in machines was one of the reasons behind the creation of the legitimate Street Fighter II: Turbo Hyper Fighting update.

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.
