Overview
Sonic & Knuckles Recomp is a native Windows and Linux port of Sonic & Knuckles for the Mega Drive, made by mstan by statically recompiling the game’s 68000 code into C. It comes from the Sonic3AndKnucklesRecomp project, which builds Sonic 3, Sonic & Knuckles and the locked-on Sonic 3 & Knuckles as separate programs.
It adds widescreen and a Knuckles & Knuckles mod. It is an early bring-up and not yet playable through the whole game.
The author says AI tools were used heavily in making it.
The download contains no game data. It needs a Sonic & Knuckles ROM, dumped from your own cartridge.
How to Set It Up
- Download the Windows zip or the Linux AppImage for Sonic & Knuckles Recomp and extract or unpack it.
- Run the program and point it at your Sonic & Knuckles ROM.
- Turn on widescreen or the Knuckles & Knuckles mod in the settings if you want them.
- The Linux AppImage needs a distribution with glibc 2.39 or newer.

What's new in v0.7.6
Sonic 3 startup save-state loads resume the saved scene and palette continuation. Sonic & Knuckles startup now follows the original queued decompression timing, correcting title-module overlap and the intro fade.
Includes Windows x64 ZIPs and Linux x86_64 AppImages for Sonic 3, Sonic 3 & Knuckles and Sonic & Knuckles. Supply your own supported ROM. Widescreen defaults to Fit to screen; saved preferences and native game saves are preserved.
Linux AppImages target Ubuntu 24.04 / glibc 2.39 or newer. Checksums are supplied for every package.
