Proto:Sonic the Hedgehog CD (Sega CD)/Ver1.05

This is a sub-page of Proto:Sonic the Hedgehog CD (Sega CD).

  This prototype is documented on Hidden Palace.

Ver1.05 is a very late Review prototype of Sonic CD. At this point in the game's development, Sonic CD was nearly finalized, with many bugs from previous builds being fixed. However, there's still some differences left. The build was dumped by drx on December 25, 2017. The build was built on August 1, 1993, about 5 days before the final Japanese version.
