Utopia bootdisk
From Wikipedia, the free encyclopedia
Utopia Bootdisk was a booting program, created by a Warez group Utopia, that allowed the playing of burnt Sega Dreamcast games. It exploited the feature of using Mil-CDs that Sega left in for developers. The program allegedly used an early teapot demo to display the rotating reindeer.
[edit] Background
The Utopia Boot Disc was released on the June 22, 2000. When released, there were no ripped games available. However, within a few hours, Utopia released Dead or Alive 2. Shortly after that, other release groups began releasing game images. Some releases required dummy tracks to be added to push the game data into the outer regions of the disc, as games such as Crazy Taxi were plagued by graphical glitches because the Dreamcast uses a CAV player. The disc spins at a constant angular velocity; data at the extremity of the disc is read faster than the data in the center, fast enough to make data streamed. However adding dummy files rectified this problem.[citation needed]
The utopia boot disc when loaded into an unmodified Dreamcast allowed a user to swap discs placing a burned CD. The uptopia bootdisc also bypassed region encoding and allowed the ability to boot most legitimate GD-ROM's from other regions . Once loaded, you are greeted with a spinning 3-D reindeer and a message to insert disc. The Dreamcast boots the disc instantly and the Dreamcast displays an image of the game on the screen.
Eventually a Boot CD was not required to boot ripped games. Kalisto was the first group to release self-booting Dreamcast games, followed by group echelon.
