Do I need the original game files to run Sonic the Hedgehog (2006) Recompilation?

Yes. The project does not include the original game's assets, so you need your own copy.

Do you have a website?

The project does not have an official website.

Where is the save data and configuration file stored?

Windows: %APPDATA%\MarathonRecomp\; Linux: ~/.config/MarathonRecomp/; macOS: ~/Library/Application Support/MarathonRecomp/. Save data is in the save folder, and the configuration file is config.toml.

How can I update the game without losing save data?

Copy and replace the files from a release over the existing installation. Save data and configuration will not be lost, and reinstalling the game is not necessary.

Can I install the game with a PlayStation 3 copy?

No. Files from the PlayStation 3 version cannot be used.

Why is the game detecting my PlayStation controller as an Xbox controller?

A third-party input translation layer such as DS4Windows or Steam Input may be responsible; disabling it is recommended for full controller support.

What other platforms will be supported?

The project does not currently plan to support platforms beyond Windows, Linux, and macOS.

About

Marathon Recompiled is an unofficial PC port of the Xbox 360 version of Sonic the Hedgehog (2006), created through static recompilation, with Windows, Linux and macOS support. It uses XenonRecomp and XenosRecomp to convert the game's PowerPC code and Xenos shaders into C++ and HLSL.
