Mod SupportDebug Mode
Sonic CD Decompilation is a native port of the 2011 remaster of Sonic CD by Christian Whitehead, made by the RSDKModding team by decompiling the Retro Engine v3 that runs it, for Windows, Linux, macOS and Android.
It adds a built-in mod loader and API, support for the updated mobile scripts with features the official PC version never had, and debug features ported from Sonic Mania. The decompilation is complete and the game is playable from start to end. The FMV cutscenes only work with the files from the original Steam release.
The download contains no game data. It needs Data.rsdk from the 2011 Sonic CD remaster, from your own copy.
