Sonic 2: Pink Edition is a modification of Sonic 2 that replaces Sonic & Tails with Amy and Cream as playable characters, Amy's sprite being based off her modern design. The changes aren't just to the asthetics though, Amy and cream bring their own movesets to the table! Amy bringing her trusty Piko Piko Hammer to swing,jump,whirl and dash through Robotnik's obstacles. Cream bringing the spindash and ability to fly, oh! don't forget about her trusty Chao, Cheese who can attack enemies, even bosses, from a distance!

A hack which combines Sonic 1 levels, Sonic 2 (final and prototype) levels, Sonic 3 levels, and Sonic and Knuckles levels into one game.

Bunnie Rabbot in Sonic the Hedgehog 2 allows players to replace Sonic with Bunnie Rabbot as the playable character in the original Sonic the Hedgehog 2 game.

Sonic the Hedgehog (also know as Sonic 4) is an unlicensed game for the SNES by Peruvian scene organization Twin Eagles Group. It is, actually, a hack of Speedy Gonzales: Los Gatos Bandidos. Notable features include Sonic's new ability to kick, and missions to free Mario from cages (upon which the latter exclaims his name).

This is a complete hack of Super Mario World. Don't expect any new graphics here; this game is all about the level design. All the levels and worlds are new, and some of the worlds have themes not present in the original game, such as a water world and an ice world.
