| Lord Flashheart said: Dreamcast used GD, a 1GB proprietary format. Why do people think it used CD. |
it was based off of CDROM and the discs were completely readable in your PC. the Dreamcast quickly became the pirate console of choice in a matter of weeks just as CD writers started becoming mainstream. Which is a major reason why the 3rd party developers quickly abandoned support and moved most everything to PS2.
