The '''Sega Dreamcast''' (ドリームキャスト) is a home video game console manufactured by [[Sega]] as a successor to the [[Sega Saturn]]. It was originally released in November 1998, becoming first machine to be released in what is now known as the sixth generation of video game consoles, sharing a platform with the [[PlayStation 2]], [[Nintendo GameCube]] and the [[Xbox]].

<section begin=intro />The '''Dreamcast''' (ドリームキャスト) is a home video game console manufactured by [[Sega]] as a successor to the [[Sega Saturn]]. Dubbed as Sega's "Super Console"{{intref|Press release: 1998-05-21: Sega Unveils Super Console!}}, it is a "128-bit" machine designed with then-cutting edge hardware and a focus on the internet. The Dreamcast was originally released in Japan in November 1998 before seeing a Western release the following year.
  
The Dreamcast was Sega's last home video game console, and was discontinued in early 2001. Roughly 10.6 million Dreamcast consoles have been sold worldwide.

The Dreamcast is a small, white box with aesthetics designed to appeal to a wide-ranging audience. It was envisioned as an "128-bit" "super console", designed to leapfrog "32-bit" and "64-bit" contemporaries in the form of the [[32-bit era|PlayStation]] and Nintendo 64, respectively (although from a technical standpoint, its main processor deals in 32-bit or 64-bit instructions, with the 128-bit figure coming from the graphics hardware). Incidentally the Dreamcast was the last home console to use "bits" as a selling point, with processing capabilities now typically measured in other ways.

Taking design cues from the Nintendo 64 and the Sega Saturn, the Dreamcast contains four control ports, a removable modem, disc drive and an extension port (as well as the expected AV and power inputs). It is not backwards compatible with any prior [[Sega]] hardware or software (although [[Dreamcast Controller|its controller]] derives from the Saturn's [[3D Control Pad]]), and operates in much the same way as the Saturn (and PlayStation) does, with a configurable settings and memory management accessed through a BIOS screen.

The Dreamcast uses a proprietary format of storage called [[GD-ROM]]s for games in order to circumvent software piracy, a strategy that ultimately backfired when the first run of discs had a high rate of defects. The format was also cracked fairly quickly (and in some cases, the pirated games were released ''before'' the legitimate versions). Sega largely had themselves to blame for the high levels of Dreamcast piracy—their use of the GD-ROM format was completely undermined by the console's support for the [[Mil-CD]] format, which allowed the console to boot from a standard CD-R. Mil-CD support was removed from the final Dreamcast revisions toward the end of the console's life.

The Dreamcast has a modest hacking enthusiast community.  The availability of Windows CE software development kits on the Internet—as well as ports of Linux ([http://linuxdc.net/ LinuxDC]) and [http://www.netbsd.org/Ports/dreamcast/ dreamcast NetBSD] operating systems to the Dreamcast—gave programmers a selection of familiar development tools to work with, even though they do not really support the high speed graphics.  A homebrew minimal operating system called [http://sourceforge.net/projects/cadcdev/ Kallistios] offers support for most hardware, while not offering multi-tasking, which is superfluous for games.  Many emulators and other tools (MP3, DivX players, and image viewers) have been ported to or written for the console, taking advantage of the relative ease with which a home user can write a CD which is bootable by an unmodified Dreamcast.

Sega released an [[arcade]] board, using the same technology as the Dreamcast, called [[Sega NAOMI]], leading to many Dreamcast-exclusive games with a high level of arcade quality. The NAOMI has the same [[wikipedia:Central processing unit|CPU]], the [[SuperH|Hitachi SH-4]], at the same clock rate, but is more powerful in other ways, with the [[wikipedia:PowerVR|PowerVR CLX2]] having a higher [[wikipedia:Graphics processing unit|GPU]] clock rate, additional [[RAM]] and [[VRAM]], higher [[Byte|bandwidth]], and faster [[ROM]] [[cartridge]] storage. The NAOMI was, in turn, the basis for two significantly more powerful arcade systems, the [[Hikaru]] (debuted 1999) and [[NAOMI 2]] (debuted 2000). Sega later packaged the Dreamcast into an arcade board as the [[Atomiswave]]. While the Dreamcast is not as powerful as 1997–1999 Sega arcade hardware, including the [[Sega Model 3|Model 3 Step 2]] (debuted 1997), NAOMI, and Hikaru, the Dreamcast surpassed the [[Sega Model 3|Model 3 Step 1]] (debuted 1996).

The Dreamcast was the most powerful home system during 1998–1999, outperforming high-end [[wikipedia:PC game|PC]] hardware at the time. The Dreamcast's [[SuperH|SH-4]] has a [[wikipedia:Geometry Engine|geometry engine]] that calculates 1.4 [[wikipedia:FLOPS|GFLOPS]] and more than 10 million polys/s,{{ref|[http://web.archive.org/web/20000823204755/computer.org/micro/articles/dreamcast_2.htm Sega Dreamcast: Implementation (IEEE)]}} higher than a PC with [[wikipedia:PIII|PIII 800]] (1999's strongest PC CPU) and [[wikipedia:Nvidia|Nvidia]] [[wikipedia:GeForce256|GF256]] (1999's strongest PC GPU) which calculates 800 MFLOPS{{ref|1=[https://books.google.co.uk/books?id=ZyZPAQAAMAAJ&q=pentium+iii+800+mflops ''Automatic Performance Tuning of Sparse Matrix Kernels'', Volume 1, page 14]}}{{ref|1=[https://books.google.co.uk/books?id=Zi8lBAAAQBAJ&pg=PA9 ''Cluster Computing'', page 9]}} and 6.7 million polys/s.{{ref|[https://www.beyond3d.com/content/articles/50/ Benchmarking T&L in 3DMark 2000], Beyond3D}} The Dreamcast's CLX2 has an additional 200 MFLOPS for [[wikipedia:Tiled rendering|tiled rendering]], and has a [[fillrate]] of 3.2 [[Pixel|GPixels/s]] with opaque polygons{{ref|[http://web.archive.org/web/20000823204755/computer.org/micro/articles/dreamcast_2.htm Sega Dreamcast: Implementation (IEEE)]}} and 500 [[Pixel|MPixels/s]]{{fileref|Edge UK 067.pdf|page=11}} (500 [[Texel|MTexels/s]]) with [[wikipedia:Alpha blending|translucent]] polygons, compared to the [[wikipedia:Voodoo3|Voodoo3 3500 TV SE]] which renders 200 MPixels/s (400 MTexels/s) and GF256 which renders 480 MPixels/s (480 MTexels/s). The Dreamcast has an 800 [[Byte|MB/s]] CPU–GPU transmission bus (polygon transfer),{{ref|[http://web.archive.org/web/20000823204755/computer.org/micro/articles/dreamcast_2.htm Sega Dreamcast: Implementation (IEEE)]}} which is faster than the Voodoo3's 533 MB/s [[wikipedia:Accelerated Graphics Port|AGP]] bus (2x AGP 2.0, transferring polygons/textures), and has a higher effective bandwidth than the 1064 MB/s transmission bus from a PIII 800EB (133 MHz [[wikipedia:Front-side bus|FSB]]) to GF256 (4x AGP 2.0, transferring polygons/textures),{{ref|[http://www.playtool.com/pages/agpcompat/agp.html AGP Peak Speeds]}} due to the Dreamcast's more efficient bandwidth usage, including its lack of CPU overhead (from operating system), and the CLX2's tiled rendering architecture: 32 bytes per [[wikipedia:Texture mapping|textured]] polygon with [[wikipedia:Gouraud shading|Gouraud shading]] (less than standard 40 bytes per polygon), textures sent directly to VRAM (freeing up CPU–GPU transmission bus for polygons), 8:1 [[wikipedia:Vector quantization|VQ]] [[wikipedia:Texture compression|texture compression]] (higher than Voodoo3's 4:1 texture compression and GF256's 6:1 [[wikipedia:S3TC|S3TC]] compression), on-chip tile buffer (eliminating need for [[wikipedia:Z-buffer|Z-buffer]]), and [[wikipedia:Deferred shading|deferred rendering]] (eliminating need to draw, [[wikipedia:Shading|shade]] or texture overdrawn polygons). The CLX2 was also the first GPU to have hardware support for [[wikipedia:Normal mapping|Dot3 normal mapping]], which the Voodoo3 lacked and a year before the GF256.{{ref|''[[wikipedia:PC Magazine|PC Magazine]]'', [https://books.google.co.uk/books?id=90OvoBUqQoIC&pg=PA193 December 1999, page 193]}} The CLX2's rendering throughput is 7 million polys/s,{{ref|[http://web.archive.org/web/20000823204755/computer.org/micro/articles/dreamcast_2.htm Sega Dreamcast: Implementation (IEEE)]}} with game engine performance peaking at 5 million polys/s;{{ref|[http://planetdc.segaretro.org/games/reviews/testdrivelemans/index.html Test Drive: Le Mans], Planet Dreamcast, [[wikipedia:IGN|IGN]]}} in comparison, a [[wikipedia:Celeron|Celeron 300A]] 450 MHz{{ref|[http://www.extremetech.com/computing/183039-20th-anniversary-pentium-specs-leak-ahead-of-launch-will-this-be-the-modern-eras-celeron-300a 20th anniversary Pentium specs leak – will this be the modern era’s Celeron 300A?] ([[wikipedia:ExtremeTech|ExtremeTech]])}} (100 MHz FSB,{{ref|[http://gamepilgrimage.com/content/95-99-pc-comparisons '95-'99 PC Comparisons]}} 364 MFLOPS){{ref|1=[https://books.google.co.uk/books?id=nXs4u5ODdPAC&pg=PA301 ''Recent Advances in Parallel Virtual Machine and Message Passing Interface'', page 301]}} with Voodoo3 3500 TV (183 MHz) renders 750,000 polys/s,{{ref|[http://gamepilgrimage.com/content/3dmark-2001se-benchmarks 3DMARK 2001SE Benchmarks]}} a PIII 800 (800 MFLOPS) with Voodoo3 3500 TV SE (200 MHz) renders 1.8 million polys/s, and a PIII 800 with GF256 has a peak rendering throughput of 6.7 million polys/s{{ref|[https://www.beyond3d.com/content/articles/50/ Benchmarking T&L in 3DMark 2000], Beyond3D}} and peak game engine performance of 2.9 million polys/s.{{ref|[http://ixbtlabs.com/articles/gf2hwtl/ Actual HW T&L perfomance of NVIDIA GeForce/GeForce2 chips], IXBT Labs}} Dreamcast game engines rendered 50,000–166,666 polys per scene (3–5 million polys/s),{{ref|[http://planetdc.segaretro.org/games/reviews/testdrivelemans/index.html Test Drive: Le Mans], Planet Dreamcast, [[wikipedia:IGN|IGN]]}} while the most demanding PC game engines of 1999 rendered 10,000–15,000 polys per scene (1–1.6 million polys/s).{{ref|1=''[[wikipedia:PC Magazine|PC Magazine]]'', [https://books.google.co.uk/books?id=90OvoBUqQoIC&pg=PA203 December 1999, page 203]}}{{ref|[http://gamepilgrimage.com/content/95-99-pc-comparisons '95-'99 PC Comparisons]}}
 
  
Compared to the rival PS2, the PS2 is more powerful at processing untextured polygons, [[wikipedia:Particle system|particles]], and [[wikipedia:Computer graphics lighting|lighting]], while the Dreamcast is more effective at rendering textures, [[wikipedia:Spatial anti-aliasing|anti-aliasing]], and [[wikipedia:Image quality|image quality]]. The PS2 has a more powerful CPU geometry engine (the [[wikipedia:Emotion Engine|Emotion Engine]] calculates 6.2 GFLOPS), higher translucent fillrate (2.4 GPixels/s), and more main RAM (32 [[Byte|MB]], compared to Dreamcast's 16 MB), while the Dreamcast has more VRAM (8 MB, compared to PS2's 4 MB), higher opaque fillrate (3.2 GPixels/s), and more GPU hardware features, with its CLX2 having capabilities such as tiled rendering, [[wikipedia:Supersampling|supersample anti-aliasing]], Dot3 normal mapping, and texture compression, which the PS2's [[wikipedia:Graphics Synthesizer|Graphics Synthesizer]] GPU lacks hardware support for. The Dreamcast's VRAM is twice as large; with tiled rendering, it could render a larger [[wikipedia:Framebuffer|framebuffer]] at a higher native [[resolution]] (without needing a Z-buffer), and with texture compression, it could compress around 20–60 MB of texture data in its VRAM. Because the PS2 has only 4 MB VRAM, it relies on the main RAM to store textures, but the PS2's CPU–GPU transmission bus for transferring polygons and textures has a bandwidth of 1.2 [[Byte|GB/s]]; while 50% faster than the Dreamcast's 800 MB/s CPU–GPU transmission bus, the Dreamcast has textures sent directly to VRAM (freeing up the CPU–GPU transmission bus for polygons) while texture compression gives it around 2–6 GB/s of effective texture bandwidth. Dreamcast games were effectively using 20–30 MB of texture memory{{ref|[http://farm6.staticflickr.com/5471/12172411045_18bfc5912f_c.jpg Hideki Sato Sega Interview (Edge)]}} (compressed to around 5.8 MB),{{ref|[http://segatech.com/technical/polygons/index.html How Many Polygons Can the Dreamcast Render?] (Dreamcast Technical Pages)}} while PS2 games up until 2003 peaked at 5.5 MB of texture memory (average 1.5 MB). PS2 game engines up until 2003 peaked at 7.5 million polys/s (145,000 polys per scene), with most PS2 games rendering 2–5 million polys/s (average 52,000 polys per scene);{{ref|[http://gamepilgrimage.com/sites/default/files/SystemSpecs/PS2/HowFarHaveWeGot.pdf Reaching for the Limits of PS2 Performance: How Far Have We Got?], [[wikipedia:Sony Computer Entertainment|SCEE]], 2003}} in comparison, Dreamcast game engines peaked at 5 million polys/s (166,666 polys per scene), with most Dreamcast games rendering 2–4 million polys/s (average 50,000 polys per scene).{{ref|[http://planetdc.segaretro.org/games/reviews/testdrivelemans/index.html Test Drive: Le Mans], Planet Dreamcast, [[wikipedia:IGN|IGN]]}} The Dreamcast is more user-friendly for developers, making it easier to develop for, while the PS2 is more difficult to develop for; this is the reverse of the [[32-bit era]], when the PlayStation was easier to develop for and the Saturn was more difficult to develop for.

Japanese Dreamcasts can be identified by the triangle at the front of the unit. Though the power LED is identical across all regions, the piece of plastic attached to the lid of the Japanese model is transparent, while in North America it is grey. The Japanese models also have the text "Designed for Microsoft Windows CE" printed on the front right, whereas Western versions say "Compatible with Microsoft Windows CE".

The Dreamcast (ドリームキャスト) is a home video game console manufactured by Sega as a successor to the Sega Saturn. Dubbed as Sega's "Super Console"[12], it is a "128-bit" machine designed with then-cutting edge hardware and a focus on the internet. The Dreamcast was originally released in Japan in November 1998 before seeing a Western release the following year.

The Dreamcast was Sega's seventh and final home video game console, and was discontinued in early 2001[13][14] due to financial constraints within the company. It had sold at least 8.2 million hardware units and 51.63 million software units by March 2001,[15], with estimates suggesting 10.6 million hardware units in total.

An arcade counterpart to the Dreamcast exists as the Sega NAOMI.

Hardware

The Dreamcast is a small, white box with aesthetics designed to appeal to a wide-ranging audience. It was envisioned as an "128-bit" "super console", designed to leapfrog "32-bit" and "64-bit" contemporaries in the form of the PlayStation and Nintendo 64, respectively (although from a technical standpoint, its main processor deals in 32-bit or 64-bit instructions, with the 128-bit figure coming from the graphics hardware). Incidentally the Dreamcast was the last home console to use "bits" as a selling point, with processing capabilities now typically measured in other ways.

Taking design cues from the Nintendo 64 and the Sega Saturn, the Dreamcast contains four control ports, a removable modem, disc drive and an extension port (as well as the expected AV and power inputs). It is not backwards compatible with any prior Sega hardware or software (although its controller derives from the Saturn's 3D Control Pad), and operates in much the same way as the Saturn (and PlayStation) does, with a configurable settings and memory management accessed through a BIOS screen.

The Dreamcast uses a proprietary format of storage called GD-ROMs for games in order to circumvent software piracy, a strategy that ultimately backfired when the first run of discs had a high rate of defects. The format was also cracked fairly quickly (and in some cases, the pirated games were released before the legitimate versions). Sega largely had themselves to blame for the high levels of Dreamcast piracy—their use of the GD-ROM format was completely undermined by the console's support for the Mil-CD format, which allowed the console to boot from a standard CD-R. Mil-CD support was removed from the final Dreamcast revisions toward the end of the console's life.

The GD-ROM format also put the console at a disadvantage when competing against the PlayStation 2 - the PS2 used DVDs, and could therefore run DVD videos making it an inexpensive DVD player as well as a video game console. DVD-ROMs also have more storage space, allowing for bigger games (though the initial run of PS2 games used a blue CD-ROM format). Sega looked into DVD technology during the Dreamcast's development but claimed it was too expensive.

The Dreamcast was the first video game console to ship with a built-in 56k modem, with broadband adapters being made available later on in certain regions. This allowed the system to connect to the internet using a custom, fully-functional web browser and e-mail client. Many games released for the Dreamcast shipped with online play modes, the most popular being Phantasy Star Online and the Sega Sports lineup (now published under the ESPN label). Although other consoles before the Dreamcast had network gaming support, such as the Sega Saturn's NetLink and the Sega Mega Drive's XB∀ND, the Dreamcast was the first game console to include this ability out of the box and is therefore considered the first internet-enabled home game system.

The Dreamcast has a modest hacking enthusiast community. The availability of Windows CE software development kits on the Internet—as well as ports of Linux (LinuxDC) and dreamcast NetBSD operating systems to the Dreamcast—gave programmers a selection of familiar development tools to work with, even though they do not really support the high speed graphics. A homebrew minimal operating system called Kallistios offers support for most hardware, while not offering multi-tasking, which is superfluous for games. Many emulators and other tools (MP3, DivX players, and image viewers) have been ported to or written for the console, taking advantage of the relative ease with which a home user can write a CD which is bootable by an unmodified Dreamcast.

Sega released an arcade board, using the same technology as the Dreamcast, called Sega NAOMI, leading to many Dreamcast-exclusive games with a high level of arcade quality.

The Dreamcast's PowerVR CLX2 was the first GPU for a home system with hardware capabilities such as bump mapping, volumetric effects,[16] order-independent transparency, and Dot3 normal mapping.[17]

Models

Main article: Dreamcast consoles.

Japanese Dreamcasts can be identified by the triangle at the front of the unit. Though the power LED is identical across all regions, the piece of plastic attached to the lid of the Japanese model is transparent, while in North America it is grey. The Japanese models also have the text "Designed for Microsoft Windows CE" printed on the front right, whereas Western versions say "Compatible with Microsoft Windows CE".
