The '''[[wikipedia:Sega Dreamcast|Sega Dreamcast]]''' is a sixth-generation console released by [[wikipedia:Sega|Sega]] on November 27, 1998, in Japan and later on September 9, 1999, in NA. It retailed for {{Inflation|USD|199.99|1999}}.

To go more in-depth, it had a Hitachi SH-4 RISC CPU at 200 MHz with 16 MBs of RAM and 8 MBs of VRAM. Additionally, on the graphic side, the console came with a PowerVR2 GPU at 100 MHz, which theoretically was capable of pushing 3 million polygons/second on-screen. The audio system had 2 MBs of audio RAM, which complemented a powerful 67 MHz Yamaha AICA sound processor with a 32-bit ARM7 RISC CPU core. The audio chip could generate 64 voices with PCM or ADPCM codec and provided ten times the performance of the [[Sega Saturn emulators|Saturn's]] sound system.

Also, Microsoft collaborated on the Dreamcast's development, and this partnership would continue later with the [[Xbox emulators|Xbox]]. What came out of this was the possibility for games to be developed for an optimized version of '''Windows CE''' (with DirectX) on each disc. However, Windows CE wasn't mandatory to use, and most developers opted for SEGA's development tools instead out of convenience. Even in major emulators, this aspect isn't implemented well.

In the same year of Dreamcast's launch, SEGA released the '''[[Sega NAOMI and variants|NAOMI]]''', an arcade system board with similar components to the Dreamcast. Sammy's '''[https://segaretro.org/Atomiswave Atomiswave]''' arcade board was also based on the Dreamcast and NAOMI.

A few years later, a successor of the NAOMI board was released in 2001, called [https://es.wikipedia.org/wiki/Sega_NAOMI_2 NAOMI 2]. It was a bit more powerful than its predecessor, having one more Hitachi SH-4 CPU and another PowerVR 2 GPU. Only 13 titles were released for this board.

==Emulators==
Actually Gaelco's (SH4) and Cave's (SH3) arcade hardware are not Dreamcast (SH4) based, Demul supports SH CPU based machines. And if you think Dreamcast emulators should support them, why not add a Capcom's medal machine and other developers' SH CPU based arcade hardware? https://youtu.be/ChYWgvxJ0EU?si=NqujOKmUdBfFYUSj. p1pkin uploaded many videos about Demul. Gaelco, Cave, Capcom and other SH based arcade hardware should be moved to another page?

===Comparisons===
;[[nullDC]]
:Can run a lot of games at great speed on a mid-end PC, and it's open-source. However, it's no longer being developed, and the more recent forks have improved upon it.
:;[[reicast]]
::Eventually, nullDC's author forked his own project into reicast, with the main objective to widen platform availability to smartphones and tablets. While wider availability is generally a good thing, this resulted in cutting accuracy corners from the nullDC codebase to achieve the speed goals necessary to run on these platforms. Advancements in mobile hardware should have led to the removal of such "hacks"; however, lack of developer resources and interest led to long delays in Reicast development, and the codebase remained virtually untouched for years before the RetroArch team began working with it as part of a "Reicast core", later named Flycast.
::;[[Flycast]]
:::Fork of reicast available as a standalone emulator and as a [[libretro]] core. Libretro collaborators, primarily [https://github.com/flyinghead/reicast-emulator flyinghead], dramatically improved Reicast in areas such as graphics, input, system clock, and Dreamcast VMU. Atomiswave and NAOMI SH-4-based arcade systems have also been added to great fanfare<ref group=N name="flycastnaomi">https://github.com/libretro/flycast/issues/136</ref>, along with full MMU support, which is needed to run Windows CE-based games such as ''Armada'', ''Half-Life'', and ''SEGA Rally Championship 2''. It has recently been tackled through an experimental branch (anyone following Dreamcast emulation over the years understands what a tough nut this is to crack). Aside from some audio stuttering issues in games such as "Looney Toons Space Race" and "Resident Evil: Code Veronica", this is a highly compatible and accurate emulator. Also there is a [https://github.com/flyinghead/flycast/issues/1390 feature request] for implementing an LLE renderer similar to the redream one.
:::;Flycast Dojo
::::Fork of Flycast with a focus on netplay features and replay. Also, available on the [[Fightcade|Fightcade]]  matchmaking service.

;[[redream]]: Multi-platform and easy to use, but it's closed-source. It has a good user interface, is easy to set up, and can run without a BIOS. Runs on [https://youtu.be/rywLHa1i9yk?t=529 low-end machines] provided that they support OpenGL 3.1. There's a payware premium version that provides high-definition rendering and additional slots for save states. Emulator work unstable on AMD GPUs with actual driver version.  Recently, redream developer "inolen" implemented an LLE video renderer that utilizes a compute shader (like [[Recommended_N64_plugins#Video|parallels-rdp for Nintendo 64]]) that allows [[High/Low_level_emulation|low-level]] graphics emulation to be run on the GPU. This can provide acceptable performance to those who want more of an accurate experience with some decent GPU to handle it comfortably. Since using a computer shader will net you some massive performance benefits, it could also allow you to upscaling/downscaling in the same manner that [[Recommended_N64_plugins#Video|parallels-rdp]] can which can be a lot of fun too. See [https://discord.gg/zuEAVTG redream discord channel] for more information.

;[[DEmul]]
:Windows-only and closed-source. Used to be the go-to emulator. It supports Windows CE games, but they generally run worse than standard Dreamcast titles. It's also more resource-intensive than other emulators. As of 2022, you´re better off with Flycast or redream for Dreamcast emulation as they are multi-platform and have higher compatibility with Windows CE games. Having said that, [[DEmul]] is still highly recommended for [https://emulation.gametechwiki.com/index.php/Sega_NAOMI_and_variants#Games SEGA NAOMI and variants].

;[[Makaron]]
:A closed-source Dreamcast emulator that was once noteworthy for being one of the two, along with Demul, that could properly play Windows CE games. It has since been superseded by newer emulators.

===VMU===
While Flycast, redream and DEmul emulators can leverage the screen of the VMU while the game is running, none of them allow you to play the standalone minigames developed for it (other than [[MAME]], but it has no interconnect support). If that's what you're after, then you should probably be looking at [[Sega VMU emulators]] instead.

Several titles for the Dreamcast included mini-games that could be downloaded onto a VMU. The Sonic Adventure series, for instance, included the Chao Adventure mini-game. In the game players could transfer Chao eggs to the VMU and play to increase the stats of their hatched Chao, whereupon they could upload their improved Chao back into the Dreamcast game.<ref>[https://sega.fandom.com/wiki/VMU Sega Wiki: VMU]</ref>
:[https://sega.fandom.com/wiki/VMU#Dreamcast_titles_that_include_VMU_games_and_extra_features Dreamcast titles that include VMU games and extra features]

===Taisen Cable===
The Taisen Cable is used for hooking up two consoles for Serial play. This was only released in Japan and a few games support it;

  What about "[https://www.dreamcast-talk.com/forum/viewtopic.php?f=5&t=10839 Dreamcast LAN games on Xlink kai?]"

===Panther DC===
The Panther DC is a flight stick peripheral manufactured by Mad Catz. Only a few games support it.

==Emulation issues==
Developer interest in Dreamcast emulation was previously hindered by the availability of the closed-source but "good enough" Chankast, and by less interest in the console relative to other 6th generation consoles. For the emulators that are either mature or maturing, a very large percentage of games work well, but some games still have problems and glitches.
