Chip McCallahan in Sonic the Hedgehog is a Sonic 1 hack created by MainMemory. It replaces Sonic the Hedgehog with Chip McCallahan, the main character in Chip's Challenge. Chip can't run fast, roll or jump high, and rings do not protect him from damage. When you die, you will get one of the death messages from Chip's Challenge, and the level will restart with no decrease in your life count.

CrazySonic is a joke hack of Sonic the Hedgehog by Ralakimus. This project was first released as a demo build in July of 2015 and was later released in October for SHC 2015. This hack is a mixture of CrazyBus' gameplay and music and Sonic 1's gameplay, plus other additions. It was designed to be as obnoxious as possible to evoke negative reactions from players. Despite this, it is generally considered to be amusing by players, especially first time players.

  Here is a hack which changes all the level layouts, all the stage music, new graphics, and also some new power-ups! Now you can also do a quick spin-dash in the air with the cost of rings.

Eggman the Dictator in Sonic the Hedgehog (aka Eggman in Sonic 1) is a rather interesting hack of Sonic the Hedgehog made by LOst - Sonic is replaced by Eggman, who runs through the stages. Due to Eggman's larger sprites, the mappings and collision engine were rewritten from scratch, and Eggman also jumps at the same height and runs at the same speed, above and below water. As a result, Eggman cannot collect rings, open item boxes, destroy enemies, be hurt by objects or drown—the only way to...

Flicky Turncoat DX is a hack of Sonic 1 by GT Koopa. It has a top down art style similar to the 8-bit game Sonic Blast. The main idea of the game that, like the namesake, the small animals that Sonic used to save now hurt you. Luckily for the player, a shield now protects from the small animals, with the added ability of saving up said shields. Another quirk of the hack is that spikes kill you instantly, ala Megaman. Finally, there is an emerald monitor hidden within each act, requiring 50...

Fly with Tails in Sonic the Hedgehog 2 is a hack of Sonic the Hedgehog 2 for the Sega Mega Drive by JoseTB which allows for Tails to fly, similar to how he does in later games. As no Sonic the Hedgehog 3 flight code was ported over the physics are a bit different. He also cannot lift Sonic, nor swim underwater, nor does he tire and descend after a long flight. It should also be noted the hack was originally created as a technical proof of concept, using machine code only, which back in 2004...

The Homing attack/jumpdash in Sonic 2 proof of concept hack is a hack which adds the homing attack to Sonic's arsenal of moves in Sonic the Hedgehog 2. The Homing attack is a move which is performed in mid-air to zoom into Badniks and objects with a high speed attack. In addition, trailing images appear when the player reaches top speed. It was created primarily by Hitaxas but with assistance by shobiz.

A reverse (and sequel) of an earlier Sonic 2 hack I did called "Keep  Tails Or Else ." You have 30 seconds to get rid of  Tails otherwise  you get a game over. Clearing the challenge immediately warps you to the next act. Go for the highest score!

So I present the most original ROM hack ever, Mario in Sonic 1. It's Mario in Sonic 1, with SMB1's physics and everything. Although he has the SMB2 super jump so that it's not  completely  impossible. This hack isn't finished, it never will be, and if I recall correctly it breaks around Labyrinth.

Planned features include a complete overhaul of the game's graphics to resemble early concept art, and perhaps new music.

Robotnik was getting frantic. Every plan he made seemed to be thwarted effortlessly by the blue hedgehog, and his ideas were getting stupider and stupider by the week. Utterly confused and enraged, he looked back on some of his old files, and realized that his previous ideas were much better than his current schemes! They'd given Sonic a run for his money, and he had just barely escaped Robotnik's seemingly fool-proof plans. Perhaps, if he lured Sonic back to South Island, he could get his old...

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.

The idea of this game is that you and another friend of yours select a character (one being Sonic and the other being Tails) and you both battle it out to try to gain as many hits on Eggman. The catch is that Eggman only gets destroyed when the timer runs down to 0 (unless it's a draw at that time, then, it will wait for another hit). The player with the most hits at the end of the timer wins! You can also win if the other player dies before the timer runs out (if respawn mode is off). The...

This hack removes all music from the game, except for the Chaos Emerald jingle. Useful if you want to listen to other music while being able to hear the sound effects. No other changes were made to the game besides the addition of text to the title screen.

Originally starting as a joke between himself and Qjimbo, later on becoming a joke hack as an idea for April Fools, with the addition of OmoChao it became a challenge-based (and playable) hack, where the objective is to collect, destroy or even touch as little as possible.

"Sonic the Hedgehog: Over 9000" is a little ROM-Hack of "Sonic the Hedgehog (16-bit)" for the Sega Mega Drive / Genesis created by EditChris. This ROM is just about adding a lot of speed to Sonic, making him look like he's high on caffeine and sugar. As said by the creator on 11/21/2013: - Quote - Now you may say: > What the hell? I'm not going to play a mini-hack that uses the same idea of others, a speed hack. But this hack is very different, this is a... "Sonic...

Sonic the Hedgehog Revelation (or Sonic Revelation) is a hack of Sonic 1 by Animemaster. This hack has many features and will continue to increase them, while the product is under way. It also plans a new zone, made of instruments known as music land. Although the creator hasn't decided on whether the art would be good enough yet. The hack contains the three hedgehogs Sonic, Shadow, Silver as they join to face Eggman once again.

Sonic: The One Ring is a hack of the original Sonic the Hedgehog game for the Sega Mega Drive, created by Mercury. Its defining (and titular) feature is that in each Act, all rings but one have been removed, and Sonic cannot complete the Act without this One Ring in his possession. Thus, in each Act, Sonic must search for the One Ring that will afford him the opportunity to progress. Several alterations have been made to the game, to somewhat balance the lack of rings, and allow backtracking...
