What you need: A Sonic & Knuckles ROM for the Mega Drive / Genesis, dumped from your own cartridge.

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

1. Download the Windows zip or the Linux AppImage for Sonic & Knuckles Recomp and extract or unpack it.
2. Run the program and point it at your Sonic & Knuckles ROM.
3. Turn on widescreen or the Knuckles & Knuckles mod in the settings if you want them.
4. The Linux AppImage needs a distribution with glibc 2.39 or newer.
