DRX, a member of the Sonic Retro Forums, has done something unprecedented in the gaming community. After years of research and detective work, he has gotten his hands on a treasure trove of materials from the golden age of SEGA, including hundreds of prototypes, documentation, and possibly other things as well.
It's not currently known how much of the material he plans to make public, but he has confirmed that he is going to release the Sonic the Hedgehog prototypes this coming Saturday, the 23rd. A large community of Sonic fans have been searching for prototypes and lost levels in the games for many years now, and to document their accomplishments so far would be beyond the scope of this article. Suffice it to say that there are a lot of people looking forward to this release.
