The '''[[wikipedia:Sega 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 with Sega for DreamCast on the Dreamcast's development (which , and this partnership would continue later with the [[Xbox emulators|Xbox)]]. The Sega Dreamcast is known What came out of this was the possibility for games to be developed for running an optimised optimized version of '''Windows CE''' (with DirectX) as an operating systemon each disc. However, Sega chose to go down a different route than what was originally planned - bundling simple operating systems within the discs themselves. Running games through Windows CE was still an option for developerswasn't mandatory to use, but and most games used Segadevelopers opted for SEGA's proprietary software development tools instead out of convenience. This 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 all 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 emulatorsof nowadays have problems running them, except from Flycast and its forks.

Dreamcast emulation is not very good. For the emulators that are either mature or maturing, a very large percentage of games work well, but many some games still have problems and glitches.

Fortunately, the first viable open-source Dreamcast emulator that has a near complete graphics renderer began appearing in June 2018 in two newly split cores inside the libretro multi-system emulator. But the more accurate core works on PC's only. Its graphics renderer can be found in a fork of the separate Reicast emulator which it backported the code from. ===VMU Emulationemulators===<!-- Update this entry if you have anything else on it -->While current some Dreamcast emulators can display leverage the screen of the VMU display when while the game is running, none of them can be used allow you to play the minigames which were made to run developed for it.
