1024 prototypes from drx. My understanding is that these were internal Sega of America archives for testing purposes prior to release. The Sonic rundown is...

Game Gear:
7 Sonic Blast
21 Sonic Spinball
2 Triple Trouble (both near-final)

Mega Drive:
7 S&K
5 "S2&K" S&K chip
2 combined S3 + S&K
8 Sonic 3D Blast
8 Sonic 2

Saturn:
Sonic 3D Tech Demo
Sonic R

What will come out of this? Your guess is as good as mine, but a lot of these prototypes are within a week or two of final so stuff like the 8 Sonic 2 prototypes are probably mostly redundant. Here's the Sonic Retro prototype forum, but note that the old S2Beta nazi registration rules apply.

edit: Gerbil put them up on HTTP for those who are torrent-averse.

GerbilEdit: Also note that these prototype ROMs are not allowed for competition on TSC. However, minor revisions, such as Sonic 2 rev00 and Sonic 2 rev01, are allowed. (TUSC may add some of the new prototypes later on.)

Best prototype ever: Sonic 3D 825. Why? This:

I ... don't get it.  What is so good about this image GS?

Look at it harder, Antiporcupine. It's going to become the newest meme among Sonic forums; it's already become the avatar for about 25% of members of Sonic sites in the know.

The eyes, the EYES :X

... if only there was an HTTP of the Phantasy Star prototypes up ...
