segagenesisrecomp
Static recompiler for the Mega Drive: it translates the ROM’s 68000 code to native C and runs it on a console runtime written from scratch, with its own video processor, the YM2612 and SN76489 sound chips, and the Z80. Each game lives in its own repository, which provides the configuration and the launcher; the Sonic 1, Sonic 2, and Sonic 3 & Knuckles recomps in this catalog come from it. It runs on Windows, macOS, and Linux.

Sonic the Hedgehog 2
mstan/SonicTheHedgehog2Recomp
Static recompilation of Sonic the Hedgehog 2 for the Mega Drive with segagenesisrecomp, its author’s own recompiler. It goes well beyond the original: rollback online play for up to four players plus spectators, local party play, Super forms for every character, and adaptive widescreen. Amy and Knuckles are playable if you also supply the ROMs they come from. There’s only a Windows build.
You needYour own Sonic the Hedgehog 2 ROM (World version, Rev A or REV01). For online play, everyone needs the same recomp version.
Sonic the Hedgehog
mstan/SonicTheHedgehogRecomp
Static recompilation of Sonic the Hedgehog for the Mega Drive with segagenesisrecomp: the ROM’s 68000 code is translated to C and runs on a console runtime written from scratch. Green Hill Zone can be completed in full, all three acts and the boss; later zones only partly work. It has a launcher that verifies your ROM, rebindable two-player controls, and an experimental widescreen mode. There’s a Windows build, plus experimental Linux and macOS ones.
You needYour own Sonic the Hedgehog ROM (World version).
Sonic 3 & Knuckles
mstan/Sonic3AndKnucklesRecomp
Static recompilation of Sonic 3, Sonic & Knuckles, and the two cartridges combined, using segagenesisrecomp. Each one ships as a separate executable for Windows and Linux. It’s at an early stage: in Sonic 3, the first zone (Angel Island) is already playable and saves work. Widescreen and Knuckles are opt-in options.
You needYour own ROM of each game you want to play: Sonic 3, Sonic & Knuckles, or both for the combined version.
