Sonic The Hedgehog: The Lost Worlds is a hack of Sonic the Hedgehog 2 by ExecByte. This hack features all of the zones that were cut from Sonic 2 during development.

Sonic the Hedgehog 3 & Knuckles (or simply Sonic 3 & Knuckles or Sonic 3 Complete Version) is a platform video game which is the result of locking-on Sonic & Knuckles with Sonic the Hedgehog 3 using the former catridge's unique "lock-on" technology. It is essentially a large combined game of its two lock-on components and contains all Zones from the said games and also contains special features unique to this game. This would have been the original Sonic the Hedgehog 3 the developers intended but time constraints by Sega resulted in the game being split into two.

Sonic the Hedgehog Megamix (commonly shortened to Sonic Megamix) is a work-in-progress multiperson disassembly modification of the original Sonic the Hedgehog videogame for the Sega Mega Drive / Genesis, developed by Team Megamix and more recently moved to the Sega Mega-CD. The game features the ability to play as one of five different characters: Sonic the Hedgehog, Mighty the Armadillo, Shadow the Hedgehog, Miles "Tails" Prower, and Knuckles the Echidna. It is an extensive reworking of the original game, featuring new art, music, abilities, layouts, and other things.

This hack started as a small joke hack, just to see if I could add something we all love to classic Sonic games; micro-transactions. This was more or less a success, although not as I imagined it. Nevertheless, I found myself just adding more and more random bits for substance, and eventually even found myself playing around with something completely foreign to me on the side. This led me to have an idea for a bossfight, and as such GHZ2 boss was born! And by that, I got an idea; What if I make full hack with new boss fights! And since then I've been pretty much adding anything to my mind comes up with, as well ass lots of bosses.But, what is this hack? Well, I dont know to be honest. It was at one point a joke, then a real hack... And then a joke again? I lost track by now. What I do know, is that none of this makes sense, especially the secrets... err, features in this hack.
