Sonic 3 & Knuckles

Sega Genesis · 2026

Sonic 3 & Knuckles on SegaGenesisRecomp, with a widescreen setting and a pre-boot launcher to greet you.

Sonic 3 & Knuckles is one of the released titles on SegaGenesisRecomp, maintained by the core team. The current release is v0.3.0 (2026-06-17), the one that introduced a pre-boot launcher UI.

What works today

The game runs as statically recompiled 68000 code through the shared runner, with the framework's clean-room interpreter tier as a fallback for static-dispatch misses.

Enhancements

A widescreen setting via the framework's opt-in 16:9 injection. Framework-level 2-player split-screen exists for the Sonic family.

No game data is distributed; the project builds from your own legally dumped ROM.
