Mil-CD

Mil-CD is a compact disc format created by Sega in 1999.

The main purpose of Mil-CD was to add multimedia functions to music CDs, for use in the Sega Dreamcast. For example, Mil-CD music releases were to feature enhanced navigational menus, internet capabilities, and full-screen video.

The Mil-CD format actually allowed hackers to by-pass the Dreamcast security, allowing the creation of such utilities such as the bleemcast! Playstation emulator, the creation of homebrew titles for the machine, and the pirating of games via the Utopia bootdisk.
