Sonic 1 in Sonic 3 S.C.E.

This is a port of Sonic The Hedgehog (1991) to Sonic Clean Engine (S.C.E.) Extended version, our heavily modified and improved Sonic 3 & Knuckles engine, which we have been using for a long time for our MD projects (such as Hellfire Saga and Sonic 3 & Knuckles: Epilogue).

Features:

* New game engine. The original Sonic 1 has serious performance issues, so the game runs much better now

* Some things are kept in the style of Sonic 3 & Knuckles. There is a mix of graphics and music from Sonic 1 and Sonic 3 & Knuckles

* Playable Tails and Knuckles. You can play as Sonic and Tails or Knuckles and Tails. The villain switches between Eggman and Eggrobo depending on which character you choose to play

* All level layouts have been updated to match Sonic 1 2013 and Sonic Origins. New paths for Tails and Knuckles in MZ3, SYZ2 and SLZ1, new secrets pretty much everywhere else

* New artwork for bosses and other stuff

* New settings menu

* Seven Special Stages. Special Stages are now only available through Star Posts, but only if you have 50 rings. The player will lose 50 rings for entering the stage

* You can get 7 Chaos Emeralds and use Super/Hyper Transformations

* Many minor improvements in polish, such as added SFX or boss intros.
