Sonic Nexus (RSDKv2)

WIN

RSDKv2-Decompilation: a complete decompilation of the Retro-Sonic Engine v2, the one from the 2008 demo of Sonic Nexus, a fan game. It adds a built-in mod loader, a settings.ini file holding all settings (as in Sonic Mania), and a dev menu reachable from anywhere with ESC if enabled in the config, with Sonic Mania’s debug features: pause with F12 and step or fast-forward with F11. It builds with CMake, with SDL2, libogg, and libvorbis, on Windows, Linux, and Mac (there is an Xcode project); don’t download the source code ZIP, since it lacks the submodules. The Nintendo Switch has a separate unofficial branch. The downloads, for Windows x86 and x64, are from May 2021: 1.0.2 (May 12, 2021) fixed a bug when loading multiple characters; the last commit is from July 2026. It doesn’t include the game: without the assets of the 2008 demo it won’t run.

You needThe data.bin file from the 2008 Sonic Nexus demo, which the README says to download from Sonic Retro and which goes next to the executable. Plus Windows, Linux, or macOS.
