Sonic the Hedgehog CD v0.70
Prerelease of: Sonic the Hedgehog CD
System: Sega Mega-CD
Build date: 1993-07-12
Source: CD-R
Found by: PACHUKA (first copy), drx (second copy)

Sonic the Hedgehog CD build v0.70 is a prototype of Sonic the Hedgehog CD for the Sega Mega-CD, named because the original discs date themselves to July 12, 1993 and one of the known copies of this prototype is labelled "v0.70". This is a later build of the game that is near completion, but is still unfinished in places and has some differences.

History

Two copies of this prototype have been found. The first copy was released by Phugolz (PACHUKA) at some point in the early 2000s and dubbed the "712 prototype". While originally dumped as a BIN/CUE, the original disc has since been sold and is now lost.

A second copy of the prototype was much later discovered and acquired by drx of Hidden Palace in conjunction with The Cutting Room Floor, along with several other prototypes of Sonic CD and other Sonic games, and dumped as part of "Sonic Month 2019" from October to November 2019[1]. This prototype, along with the other Sonic CD prototypes, was released to the public on October 26, 2019. Though three files on the disc have some differences, this copy is otherwise identical to the previously released copy.
