Mil-CD information Extended

The Dreamcast's copy protection was a new type of media called GD-ROM, consisting of a 1.5gig inner layer of game data and a outer layer of regular CD data/cdda.

The Mil-CD is a compact disc format created by the video game company Sega in 1999, the main purpose of Mil-CD was to add multimedia functions to music CDs, for use in Sega's Dreamcast games console. For example, Mil-CD music releases were to feature enhanced navigational menus, internet capabilities, and full-screen video.

The Mil-CD format allowed hackers to by-pass the Dreamcast security, allowing the creation of such utilities such as Bleem!cast the Playstation emulator, the creation of homebrew titles for the machine, and ability to boot copied games and games from other regions via the Utopia bootdisk.

Mil-CD support was removed from the final Dreamcast revision, Dreamcast version 2.
