DC Tonic
At E3 2001, a disc of the games from the best independent Dreamcast developers called DC Tonic was given out to attendees of the show. An early demo of Cool Herders was among those games. The quality of the games on the DCTonic disc were so impressive, that the disc was reportedly mistaken as an official Dreamcast demo disc.
