The '''[[wikipedia:Sega collaborated Dreamcast|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}}. More in depth, it had a Hitachi SH-4 RISC CPU at 200 MHz with 16 MB of RAM and 8 MB 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 a 2 MB 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 SegaSEGA's development tools instead out of convenience. Even in major emulators, this aspect isn't implemented (or 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 it's predecessor, having one more Hitachi SH-4 CPU and another PowerVR 2 GPU. Only 13 titles were released for this board, although most emulators of nowadays have problems running them, except from Flycast and its forks.

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.:;[[reicast#Libretro_core|Flycast]]:Fork of reicast available as a standalone emulator and as a [[libretro]] fork of reicastcore. libretro Libretro collaborators, primarily [https://github.com/flyinghead/reicast-emulator flyinghead], dramatically improved Reicast in areas such as graphics, input, system clock, and Dreamcast VMU.

Even full MMU support, which is needed to run WinCE-based games such as "Armada", "Half-Life" and "SEGA Rally Championship 2", has recently been tackled through an experimental branch (anyone following Dreamcast emulation over the years understands what a tough nut this is to crack).

Windows CE games emulation is still poor and slow. ===Poor VMU emulation=emulators==<!-- Update this entry if you have anything else on it -->While current some Dreamcast emulators can leverage the screen of the VMU while the game is running, none of them allow you to play the minigames developed for it so playing those minigames would require another emulator. The problem is there aren't any complete lists of See the main page on VMU emulation [[Sega VMU emulators, and the emulators that can be found are poorly documented|here]].
