About this project
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.
What you need
Your own Sonic the Hedgehog 2 ROM (World version, Rev A or REV01). For online play, everyone needs the same recomp version.
