Pana Der Hejhog is a hack of Sonic the Hedgehog for the Sega Mega Drive/Genesis by MarkeyJester. It features one new level, 'Mystic Island Zone' and a purple hedgehog that resembles Sonic, 'Pana'. It is notable for having extremely detailed graphics and fluid animation.

OMG THE RED RINGS is a hack of Sonic the Hedgehog (16-bit) for the Sega Mega Drive/Genesis by Fiz. In this hack, all the rings and monitors are replaced by bouncing red rings. Touch one of them and you get killed. According to many people who posted in the original release thread, this hack is extremely hard, and it is probably impossible to beat several of its acts. However, it was received very well by the general audience, including several renowned members; this granted Tech Membership to Fiz (she's now an Oldbie).

Not-so-Super Sonic 2 is a hack of Sonic the Hedgehog 2 by MainMemory. It was first posted in the Random Hack/Mini Project thread, where nobody paid any attention to it. MainMemory said himself that updates would be unlikely, but has changed his mind.

Sonic 3D: No Flickies is a hack of Sonic 3D: Flickies' Island made by Sik. The game remains mostly unchanged; however, the Flicky collection system (part of the core gameplay of the original game) has been removed, allowing the player to complete the levels without needing to collect all the flickies in the level to advance. This makes it much more similar to traditional Sonic games, where the goal is to simply make it to the end of the level without dying.

This hack was later built upon further in the hack, Super Sonic in Sonic 3D, which was also created by Sik.

Mr. Needlemouse is a hack of the original Sonic the Hedgehog game for the Sega Mega Drive / Genesis, by MKAmeX. It replaces Sonic the Hedgehog with one version (arguably the strangest) of his designer Naoto Ohshima's early prototype of the character, Mr. Needlemouse. Planned features include a complete overhaul of the game's graphics to resemble early concept art, and perhaps new music.

Motobug the Badnik in Sonic the Hedgehog (aka Motobug in Sonic 1) is a hack of Sonic the Hedgehog for the Sega Mega Drive, by Polygon Jim. As its title suggests, in this hack the main character Sonic the Hedgehog is replaced by Motobug, one of Dr. Robotnik's badniks.

So far, some of Sonic's main sprites and animations have been replaced by those of Motobug, Motobug's speed has been decreased (except when powered-up by aSpeed Shoes monitor, which are more numerous), and the sprites of Roller badniks in Spring Yard Zone have been replaced by those of Sonic (referencing a common interpretation by fans that Roller is a robotic impersonation of Sonic, something that officially appeared in later games in the form of Metal Sonic and various others).

Of the first release, Polygon Jim stated that he had only tested and confirmed Green Hill Zone (Acts 1-3) for completability. However, upon testing, Katelynn andRGamer2009 reported that other Acts are completable, including:

• Marble Zone Act 1
• Spring Yard Zone Acts 1 and 2
• Labyrinth Zone Acts 1 and 2
• Star Light Zone Acts 2 and 3
• Final Zone

Sonic the Hedgehog Mega Blitz is a hack of Sonic the Hedgehog (16-bit) made by SSE. It is named "Sonic the Hedgehog Mega Blitz (Sonic Mega Blitz)" Due to the fact that the hack is a "blitzed out" version of the original game.

Mecha Sonic in Sonic the Hedgehog (aka Mecha Sonic in Sonic 1) is a hack created as a proof-of-concept by Iron Sonic of Sonic the Hedgehog for the Mega Drivein which the player plays as Mecha Sonic from Sonic & Knuckles. The controls are the same as in the original Sonic 1, save for the ability to perform the Spin Dash. Each sprite has been edited, and the player size and other aspects of the Sonic object have been changed to accommodate Mecha Sonic's larger size.

Whilst the game is mostly playable, there are certain areas in the game that Mecha Sonic cannot complete due to his increased size; prime examples of this includeSpring Yard Zone and Scrap Brain Zone.
