SAGE 2020 - Demo Sonic 1: Green Hill Revisited


UPDATE AS 01/18/2021:
Sonic 1 Revisited is canceled due to decompilation of Sonic 1 and Sonic 2 2013 releases. S1R is now a standalone Green Hill tech demo of Orbinaut Framework. We might update the project later to keep it clear that it has been discontinued.

We'll continue to develop our framework, so make sure to follow our twitter linked down below if you are interested.

"Sonic 1: Green Hill Revisited" is a remake of Green Hill Zone build from the ground up, developed with GameMaker Studio 2 using our own private framework called "Orbinaut Framework", by me and my friend MicG.
The main goal of the project is to make it as close to original game as possible by doing a lot of researching in the original game code.


• Game-styled Main Menu right on the Title Screen. Simple and awesome-looking.
Fully playable Green Hill Zone including boss. (boss was the harder thing in the whole project)
• MegaDrive accurate linear colour levels and palette limitations.
Full Xinput gamepad support. Everywhere. Literally. (We support it even if the game is closed).
• Four aspect ratios (4:3, 16:9, 16:10, 21:9) and four window modes. Hey ultrawidescreen users, we know you exist!
• Three soundtrack types: original, remixed (act-based) and 2013 Mobile HQ. Awesome choice if you tired of original GHZ theme!
Optional Spindash and Speedcap. It's up to you to decide, what you really want to be featured in your walkthrough.
• Functional pause menu! Restart current act without losing a life or back to the Main Menu.
Discord Rich Presence support. Wait, you're already playing Act 3? HOW?

Please, make sure your PC has at least this setup and only after that comment about any crashes.

• 64Bit OS Windows 7
• CPU with 2 Cores
• GPU supporting Shader Model 3.0
• 256MB RAM
• 50MB of disk space

Thank you :)
its soo amazing i love it it looks like the mobile port but better i hope the full version get released soon! :)
It looked great and was really fun and the remixed music was amazing
This is just absolutely stunning, honestly. You'd better believe I played through Green Hill Zone acts 1 to 3 with every aspect ratio and soundtrack option! Speaking of which, I love those remixes in the 'remixed' option. What's here already is so brilliant, I can't wait for future updates!

This is a good Sonic 1 PC port, no doubt, I have experienced no glitches either. Maybe add some options for more smoother animations and more Sonic abilities like the peel out etc. My main issue is that I can't change controls. This is so annoying! Using the arrow keys and S to play is so uncomfortable. We should be able to customize them or at least have WASD and Space Bar as a preset control option.
Sonic 1 Revisited is canceled due to decompilation of Sonic 1 and Sonic 2 2013 releases. Aw man this was actually better than the 2013 releases
