http://www.nintendoplayer.com/unreleased/sonic-crackers/ This article says Clint Dyer is responsible for sneaking out that Proto archive that drx released sometime back. The article also talks about the origins of Sonic Crackers. Apparently a guy mass copied them onto spare eeprom boards before he left Sega and thought they would sell cause of name recognition. It's not a true prototype as in they were used for testing. Kinda a repro but not really since it used official dev boards. Clint Dyer apparently was in the special thanks section of Knuckles Chaotix credits.
You're a few months behind me I came across the name while hunting for Sega Neptunes. I noticed a single Neptune prototype has journeyed across the US for the best part of 20 years - it's recognisable by the bits of white paint near the cartridge slot. As far as I can tell there is only one in public hands, and this lad is believed to have put it there. It's now part of a travelling collection. Much like that "Play Station" SNES prototype that showed up recently.
