Sonic 3: Angel Island Revisited (Sonic 3 A.I.R.) is an unofficial port of Sonic 3 & Knuckles for Windows PCs. It very closely resembles the original game, but adds features you would only expect from a modern fan game engine - including full support for 16:9 widescreen display, alpha transparency effects, and smooth 360° rotation.

Sonic the Hedgehog: The Next Level is a overhaul modification of Sonic the Hedgehog developed by MarkeyJester. This time around Sonic explores a new otherworldly zone- for that's exactly what it is! It seems Dr.Robotnik has grown tired of the same shtick and is now trying to conquer the Gust Planet! He has trapped the Animals of the planet in his new models of badnik and has managed to collect a Chaos Emerald! He's used this emerald to power his new machine the Reality Bender! Sonic soon catches on to Dr. Robotnik's scheme and makes his way over to the Gust Planet Zone himself to put a stop to his evil scheme!

Sonic 2 XL is a hack of Sonic the Hedgehog 2 for the Sega Mega Drive by Captain Bozo and Ranger. Rings are replaced with onion rings, and Sonic becomes fatter after eating them.

Robotnik's Revenge is a hack of Sonic the Hedgehog 2 by ColinC10. It is a "boss rush" hack, in which all seventeen bosses from Sonic the Hedgehog and Sonic the Hedgehog 2 are fought in a somewhat arbitrary order over the course of a single level. The game takes place in Death Egg Zone from Sonic 2, and is meant to imply that there is more to the ship than there is in the original game. Time spent completing the boss run is kept and the total time is given at the end of the course, along with a ranking. In Time Attack mode there are infinite lives and rings that can be found in-between battles. In survival mode, there are only 3 lives and no rings.

Dr. Robotnik has stolen the Red Chaos Emerald, causing the other five to "lose balance" and scatter themselves into a parallel universe. As a result of the instability, South Island is now sinking into the ocean. It is up to Sonic and Tails to find the Chaos Emeralds and restore harmony to the universe, or else the innocent residents of South Island will find themselves taking a long swim.

This is a completely different game than its 16-bit counterpart on the Genesis/Mega Drive, and was originally released on the Sega Game Gear and Master System. To stop the evil Dr. Robotnik, Sonic must traverse six zones consisting of three levels each. Most of the zones are based on those in the original game, but some are entirely new, including a jungle environment and a huge airship. Other unique differences are one level that scrolls automatically and one that is aligned vertically instead of horizontally. Most of the enemies (mechanized animals, defeated by Sonic's spikes when jumping or rolling) and power-ups (speed-ups, shields, extra lives) are the same as in the Genesis version as well. Sonic can pick up golden rings for protection (when hit, he simply loses all of his rings instead of a life) and bonuses: 100 rings gain Sonic an extra life, and 50 remaining rings at the end of a level allow access to pinball-themed special stages full of bumpers and springs. The final level of a zone is always a boss fight against Robotnik. Some of the boss fights differ in the Master System and Game Gear versions of the game, with special designs for the handheld version due to the smaller visible screen area. Sonic should also collect the six Chaos Emeralds to keep them from falling into Robotnik's hands. In a departure from the original game, these are not hidden in the special stages but somewhere in the regular levels.

Sonic and Tails are back with three times the fun and three times the trouble! Dr. Robotnik is building the ultimate super-weapon with the help of Knuckles, but you can stop him by getting the Chaos Emeralds first. Rip across snow and water on Sonic's new jet skateboard or zip underwater in Tails' "Sea Fox". But look out - Nack the Weasel is after the Emeralds, too!

An extraordinary amusement park has been seen orbiting around the home planet of Sonic the Hedgehog, and rumors are spreading that an alien race of Wisps, who have a unique colorful energy, are being held captive there by the evil Dr. Eggman. Soon after arriving at the amusement park, Sonic discovers he is able to use these mysterious alien forces to help the Wisps escape!
