Sonic 2: S3 Edition

Credits: Alriightyman

Sonic 2: S3 Editon is an assembly hack of Sonic the Hedgehog 2 by Alriightyman for the Sega Mega Drive. It places the levels of Sonic 2 into the engine of Sonic the Hedgehog 3; providing many of its features, including Act transitions, a Sonic 3 Save Screen, and Tails ability to fly.

==Features==
*Title Screen has been changed to make it a bit more like Sonic 3 & Knuckles's.
*Knuckles is implemented, complete with all of his abilities from S&K.
*Sonic 3K data select screen is implemented.
*All item boxes from Sonic 3 & Knuckles's are implemented.
*Sonic & Tails now use their sprites from Sonic 3 & Knuckles's.
*Sonic can now perform his Double Jump actions from Sonic 3 & Knuckles's.
*Tails can now fly/swim. However, he cannot pick up Sonic in "Sonic & Tails" mode.
*Super transformation is activated via pressing A, B, or C twice, thus the Super transformation glitch at the end of levels is removed.
*There are now transitions between acts and zones.
*Emerald Hill and Chemical Plant now have mini-bosses between Act 1 and Act 2.
*Emerald Hill and Chemical Plant also have signposts at the end of act 1 that fall down from the top of the screen, and item boxes can be uncovered underground as in Sonic 3K.
*Some zones, such as Emerald Hill and Casino Night, have different Act 1 and Act 2 music.
*The 2P VS option is removed.
*For the zones with mini-bosses, S&K's mini-boss music was ported.
*The level select menu is now separate and not activated by pressing A+Start on the "1 Player" option, a la Sonic 3.
*The HUD is changed so that it now displays the current powerup(s) you have (if you are Super Sonic/Super Knuckles, this is represented by an invincibility icon).
