Sonic Chaos Quest v2.0 is a modification of Sonic the Hedgehog.

Story:
Exploring Mobius seas Eggman found the Chaos Island. It has giant lake, on bottom of which the sunken ruins of Chaos Shrine which contain the inexhaustible power of Chaos are lying. In order to increase the power of his mechanisms Eggman built the Hydrostation on this lake and plans to conquer the world with the power which he got.
Residents of the island asked Sonic for help, so he teamed up with Mighty, Tikal and Metal Sonic to start their Chaos Quest to stop Eggman's evil plans once again!

Sonic Labyrinth 2 is a hack by Team Overload, Unlimited Trees.

While I was creating that terrible Pespi hack, I thought to myself "Man, why can't I just play normal Sonic 2?" And then, I thought to myself "Why isn't there a sequel to Sonic Labyrinth?". So, I put my skills to the test, and created what, basically, is just vanilla Sonic 2! No major changes, aside from a few "fixes". For example, remember that annoying control lock that stopped you from jumping and moving while spinning? Well, now you can't even jump while rolling! Now there is no control lock problem to deal with, because it doesn't exist! Another thing I should add, is that there is some bug in the game. I can't really explain it, but it's not like it's noticeable or anything!. Anyways, this is just normal Sonic 2, don't bother if you don't want to play the same game again.

Also, this game was created using SonED2 and Sonic 2 Github disassembly. Why did I use SonED2? Because, otherwise, this game would be impossible!

Spoliers: This hack is simply just a joke hack I made while I was bored. The game IS possible (except for one problem), but it would require some skills in order to beat. You would have to go on very specific routes in order to win, as well as be very careful on what you do. My tip: Don't spindash too much. It would mess you up a lot. Also, make sure you know a lot about Sonic's physics, otherwise you wouldn't make it very far.

This is a Sonic 1 hack that I release a new build of each year on Halloween. This hack is mainly focused on art and music edits, however, a new monitor has been implemented in one of the zones.

Sonic 1: Reverse Curse is a hack based on Sonic 1 made by Campbellsonic

Story:

Sonic the Hedgehog has been cursed! Now, when he collects rings, his rings counter counts DOWN instead of up! And if he collects a ring when he has a counter of 0, it's lights out. Sonic 1 never seemed so... Intimidating.

Sonic 1 NAC Tiny Version (Tiny as in short version) is a hack based on Sonic 1 made by Campbellsonic is a simple but advanced sonic 1 hack that has different events and concepts with in each level. Therefore making each level different and unique to the standard level edits that you find in must hacks, especially some of mine.

Hack Story line:
One day sonic decided to take a break from his friends and the stress that he has been going through, and went back to south island. however when sonic had arrived at south island he noticed something was different, everything seem to have changed colour and seemed to be a lot darker then it use to be, And so he decided to explore. After spending 10 minutes exploring the changes; sonic noticed the that the badniks that he destroyed before had reappeared in green hill zone. Then sonic realized that robotnik was back to no good once again and goes to save south island once again.

Level Information:
You may notice that all of the main levels have a wall that seems to be unbreakable at the end of the level, this is because your required to find and hit an "S" monitor in order for that wall to become breakable and before your able to finish the level. Act 2 of the main green hill zone will start off normal but then you will given a platforming challenge. Act 3 of the main green hill zone is a auto running level inspired by sunset park act 3 from sonic triple trouble, where you have no control over sonic's speed or direction he is running in, all you can do is make sonic jump.

Sonic 1 - Back to South Island is a Sonic 1 hack made by HyperSonic16.

This hack includes new audio, new stage/special stage layouts, new sprites, SPINDASH!!!!!(of course a spindash XD), New level art, and a bunch of badniks(Thanks Robuttnik!) You all are probably expecting a story, so here it is, nice and sweet:

Story:

Its the Christmas season, and everyone is doing their thing. Tails and knuckles go off to celebrate Christmas on Angel Island. While this happens, Sonic decides to go back to South Island (hence the name of the hack), to celebrate and check up on the flickys. Eggman, strangely had a similar idea, but he plans to robotize the flickys, and rebuild his base. When Sonic arrives, he finds a bunch of badniks, and he immediately knows that Eggman is there. So sonic, being the hero he is, he travels out to stop eggmans plans.

Team Overload presents, Sonic 1 - Warped World! This hack has undergone a quite a lot of changes since last year, including brand new level layouts, a lot of new music, and some other really cool features that you'll see in game! This year's entry only has 3 playable levels so far, but after completing the demo, you will gain access to the level select, where you can see what is in store for future releases!

Story:
After the events of Sonic 3 and Knuckles, Sonic lands back on Mobius. But because of his extended use of Super Sonic, he has lost his abilities. The Tornado lands on an unknown area so Sonic goes and explores. He comes across a whole lot of badniks and thinks straight away that Eggman had crashed there. Eggman, who barely made it, set up shop in an abandoned factory and built "Robotic Empire". Sonic, on the other side of Chaos Island, needs to make it through the six zones to destroy the Chaos Extraction Engine in Robotic Empire, and regain some of his lost abilities!

Socket the Hedgeduck is an in-progress, unofficial port of levels and assets (art, custom objects, and more) from the Sonic clone titled "Socket/Time Dominator" to the Sonic 1 engine. (The title is a portmanteau on "Socket" and "Hedgehog", since the hack contains assets from Socket shoved into the Sonic 1 engine). It contains various standard platforming zones, bonus zones, and acts from the High Speed Zone as special stages, as well as various other advanced engine features and new content (such as an expanded music playlist with custom SMPS tunes, warp doors, a bonus and special stage zone feature, and much more). This is a v0.3 demo created specifically for the SHC'16!

Pepsi in Sonic 1 is a ROM hack of Sonic the Hedgehog by Unlimited Trees (a.k.a HorriblePerson on Sonic Retro). It is a parody hack of a lot of ROM hacks out there, which is why there are things such as horrible level "designs", generic palettes, and the usual character switch. This ROM hack features 6 full length zones (plus bonus stages), 3 (+1) playable characters, and many art edits and secrets!

A hack based on Sonic 1 game made by VAdaPEGA featuring Pantufa the Cat.

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!
