Mil-CD was a compact disc storage format created by Sega in 1998 to add multimedia features to normal CDs for use on the Sega Dreamcast. The extent that Mil-CD was used is unknown, however as code was not authenticated, it allowed hackers to run their own code on the Dreamcast, opening the way to homebrew games and demos from the Dreamcast's early years.
