Sonic the Hedgehog CD (Jun 21, 1993 prototype)

A prototype of Sonic the Hedgehog CD for the Sega CD.
==Notes==
*The Special Stage has been implemented in this build and is noticeably different in comparison to the final version. The palette for the UFOs rotates between various colors. The ring counter continuously counts up. Falling in water will cause the stage to end prematurely and crash the game. To move Sonic, you have to press the A button to accelerate rather than use the directional pad.
*The final title screen is present in this build although the word " SEGA " are thinner than the final version .
*The blue ring, ‘S’, and clock monitors are still present in this build. The blue ring has a different functionality in comparison to earlier builds. Unlike previous builds, the monitors play a specific sound when you open one. In this build, the blue ring acts like a shield.
*Sonic’s “Yeah!” PCM sample is different.
