![]() BIOS AND FLASH FOR DREAMCAST ROM SOFTWAREHowever, the Dreamcast did retain the ability to read standard CD-ROM discs, and thus still suffered from software piracy as bootleggers managed to fit certain games on CDs and exploit the Dreamcast console's compatibility with the MIL-CD format. GD-ROM was created because the standard CD-ROM was prone to piracy and reaching the limits of its storage capacity, while implementing the then brand-new DVD-ROM technology would have made console production too costly. The format was developed for Sega by Yamaha, and first commercially appeared with the Dreamcast's Japanese launch in November 1998. The last disc-based Naomi 2 and Triforce games were released in 2006 which marked the final releases using the GD-ROM format. With the release of the Sega Lindbergh in 2005, Sega moved on to DVD discs and continued to use satellite and internet technology in the arcade. In addition, GD-ROM proved to be an ineffective anti-piracy measure when it was discovered the Dreamcast's forgotten MIL-CD functionality could be exploited to boot games burned to CD albeit with some content removed.Īfter the discontinuation of the Dreamcast worldwide on March 31, 2001, Sega continued to use the GD-ROM format in arcades with the Sega NAOMI 2, Triforce and Sega Chihiro. The Dreamcast ended up being the only sixth-generation console with a disc based on CD technology rather than DVD technology even the Nintendo GameCube's smaller 8 cm discs held 50% more data due to being based on DVD technology. ![]() It is similar to the standard CD-ROM except that the pits on the disc are packed more closely together, resulting in a higher storage capacity of 1 gigabyte, a 42% increase over a conventional CD's capacity of 700 megabytes. It was developed by Yamaha to curb piracy common to standard compact discs and to offer increased storage capacity without the expense of the fledgling DVD-ROM.
