Sonic the Hedgehog 2 is a platforming action video game. Developed by Sonic Team and Sega Technical Institute in 1992, it introduces new mechanics to the series, and the lovable young fox known as Miles "Tails" Prower. The massively successful sequel to the original Sonic the Hedgehog, Sonic 2 stands as the second best-selling Sonic game in history, and is considered by many fans as the best Sonic game.

A 2-D side-scrolling platformer, you control Sonic, a blue-colored hedgehog that runs pretty darn fast across the stages (zones as they are called in the game). Alternatively, the player can also play as Tails, who either functions identical to Sonic. Scattered throughout the zones are golden rings that Sonic can collect, which allows him to not only take damage, but allow access to special stages. The special stage, which is now a pseudo-3D tube, involves collecting a certain amount of rings and avoiding bombs.

Returning from his previous defeat, Dr. Ivo Robotnik plans world domination once again by kidnapping and converting animals into robots, and collecting the seven Chaos Emeralds. Unlike his previous frenzy with Sonic, Robotnik has built the Death Egg, a giant battle station orbiting the Earth, and intends to conquer with it. Sonic (now followed by Miles "Tails" Prower) set off to collect the Chaos Emeralds and defeat Robonik once and for all.

Brand new version of the hack Sonic 2 SatAM Edition, this time trying to follow more closely my original idea, to change Tails for Princess Sally. Unhappily I could just change the character main sprites so far, so special stages and ending still show Tails instead, as much as any text was changed so far as well. Note: If you think you can help me to fix that problems, just contact me by e-mail, capitaoazulao@gmail.com, I would be so pleased to conclude this project as it should be :)

-- In this hack so far

- new sprites for Sonic;
- Tails main sprites, and Signposts changed for Sally Acorn;
- Western design for Doctor Robotnik;
- creepier and less colorful design for many badniks, to make them look more like soulless machines, just like in the show.
- Version 2.1 brand new addon - now with Sally's sprites on special stages as well



-- What I wanted to do but couldn't so far (helping from more experienced hackers welcome):

- Change all Tail's sprites for Sally's (including endings and HUD's);
- Replace all text about Tails as well;
- Maybe re-editing Robotnik's sprites, as I think they could be better used.
