TheDreamcast^[a] is ahome video game console developed and sold bySega. The first of thesixth generation of video game consoles, it was released in Japan on November 27, 1998, in North America on September 9, 1999, and in Europe on October 14, 1999. The fifth and final home console produced by Sega, the Dreamcast is the successor to theSega Saturn, whose commercial failure prompted the company to release it only four years after its predecessor's initial release.

All licensed games for the Dreamcast were released on theGD-ROM format, a proprietaryCD-basedoptical disc format jointly developed by Sega andYamaha Corporation that was capable of storing up to 1GB of data.^[1] The Dreamcast itself featuresregional lockout.^[2][3][4]While the higher-capacityDVD-ROM format was available during the console's development, its then-fledgling technology was deemed too expensive to implement at the time,^[5] which resulted in ramifications for Sega when competitors such asSony'sPlayStation 2 came to market; the Dreamcast was unable to offer DVD movie playback when the general public began switching fromVHS to DVD, and its games were unable to take advantage of the DVD's higher storage capacity and lower cost.^[6][7] Furthermore, an exploit in the console'scopy protection system via its support for the little-usedMIL-CD format effectively allowed users to play many games burned ontoCD-Rs, without any hardware modifications.^[8][9]

The Dreamcast's initial release in Japan had four launch titles, which wereVirtua Fighter 3tb,Pen Pen TriIcelon,Godzilla Generations, andJuly.^[10] The North American debut featured 19 launch titles, which included highly anticipated ones such asSonic Adventure,Soulcalibur, andNFL 2K.^[b][11] The European introduction was originally going to feature 10 launch titles, but the list increased to 15 as its delay from the original September 23 launch date allowed the inclusion of a handful of additional titles.^[c][14] Due to the similarity of the Dreamcast's hardware with Sega's ownNew Arcade Operation Machine Idea (NAOMI) arcade board, it saw several near-identicalports ofarcade games.^[15] Plus, since the Dreamcast's hardware used parts similar to those found inpersonal computers (PCs) of the era, specifically ones withPentium II andIII processors, it also saw a handful of ports ofPC games.^[16][17] American third-party publisherElectronic Arts, which had extensively supported Sega's prior consoles beginning with theSega Genesis, elected not to develop games for the Dreamcast due to a dispute with Sega over licensing.^[18][d]

Sega discontinued the Dreamcast's hardware in March 2001, and software support quickly dwindled as a result.^[21][22] Software largely trickled to a stop by 2002,^[20][23] though the Dreamcast's final licensed game on GD-ROM wasKarous, released only in Japan on March 8, 2007, nearly coinciding with the end of GD-ROM production the previous month.^[20][24][25] Sega also assisted later with a reprint ofBorder Down, sold at Japanese retailers in January 2008.^[26] The final first-party game for the Dreamcast wasPuyo Puyo Fever, released as a Japanese exclusive on February 24, 2004.^[27][28]
