Overview
Sonic 3 Recomp is a native Windows and Linux port of Sonic the Hedgehog 3 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 a playable bring-up: Angel Island Zone works, and the rest of the game is still being brought up.
The author says AI tools were used heavily in making it.
The download contains no game data. It needs a Sonic the Hedgehog 3 ROM (the Sonic 3 cartridge on its own), dumped from your own cartridge.
How to Set It Up
- Download the Windows zip or the Linux AppImage for Sonic 3 Recomp and extract or unpack it.
- Run the program and point it at your Sonic the Hedgehog 3 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.
