    This is a port of Sonic The Hedgehog (1991) to Sonic Clean Engine (S.C.E.), 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).

    TheBlad768 had the idea for this project back in 2017, when we were working on Sonic Virtual Adventure. But at the time, porting the entirety of Sonic 1 to another engine was too difficult a task, and we had other big projects that couldn't wait. So it was decided to leave the idea for better times. In 2022, TheBlad768 had gained more knowledge and decided to return to the idea. By then S.C.E. was ready, so we started from scratch.The porting work took our team 2 years. But this is not the final version and we will continue to improve it with future updates.

    The original game was very poorly optimised and had severe FPS drops, so all the code from the original game was rewritten to ensure better performance.

    But the main reason for making this port is to help other ROM hackers. In the future, we plan to open source this project's codebase so that anyone can use it to create or improve their own ROM hacks. You can use it as a base for your own project, or for whatever other purpose you can think of. We just want to try and help others. There are no other goals here. We really hope you find something useful in S.C.E. :)

    Unfortunately, the source code is not available at the moment, as we're still looking for bugs and fixing them. And we hope that the open beta test will help us find more problems to fix.

    We are looking for feedback. Your opinions and bug reports are very important to us!

    Changes:

    • 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, but unfortunately you can't use Super/Hyper Transformations yet. This may be added in future updates.
    • Many minor improvements in polish, such as added SFX or boss intros.
    Many of those changes will only be appreciated by other ROM hackers, not the average player. The core gameplay of the game has not been changed due to the nature of the project, so it's possible that the source code will be much more interesting than the hack itself.

    Cheats and Secrets:

    • S1 Level Select: U, D, L, R, A+Start on the Title Screen
    • S.C.E. Level Select: U, D, L, R, A+C+Start on the Title Screen
    • Hidden Credits: Hold A+C on the Sega Screen
    • Debug Mode: 1, 9, 9, 1, 0, 6, 2, 3 in the Sound Test of any Level Select;
    • All Emeralds: 4, 1, 2, 6 in the Sound Test of any Level Select;
    • Results skip: A, B or C during Got Through/Special Stage screens.
    Roadmap for the future:

    • Act transitions. Levels have been edited to allow for these, but unfortunately they couldn't be implemented in time for SHC.
    • Fix Knuckles' socks palette.
    • SRAM (?)
    • Super/Hyper transformations (?)
    • Flamedriver has some issues that need to be addressed. Music speed-up is reset after 1UP. Continuous SFX have conflicts with other SFX. Continuous flag is not reset when playing normal SFX.
    • Of course all the bugs that are found will be fixed as well.
    (?) - We'd like to know if this really needs to be added.

    We look forward to your feedback!
