Quick Answers
What should I know before playing Sonic the Hedgehog CD?
It's a pre-release, development version saved from the archives, showcasing changes to sound, text, and the overall polished experience later shipped.
On platforms supporting this build?
This prototype must be played on an emulated Sega CD (Mega CD) environment with compatible software and correct game-files, as it will not run on original hardware out of the box.
Will controls differ from other versions?
Core controls use standard emulated commands (arrow keys/WASD, Z/X/Space) but may need adjustments inside your emulator settings.
