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 ($298.72 in 2018 money)99|1999}}. It had a Hitachi SH-4 RISC CPU at 200 MHz with 16 MB of RAM and 8 MB of VRAM. It had a PowerVR2 GPU at 100 MHz, which theoretically was capable of pushing 3 million polygons/second on-screen. There is 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.. Sega also 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.

Dreamcast emulation isn't 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.

In recent times, the open-source community has gotten a better leg to stand on thanks to RetroArch's reicast cores. Their team has been integrating a version of reicast that deals with many graphical issues (elaborated on above)Windows CE games emulation is still poor and slow.

===Poor VMU emulationemulators===<!-- 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  ElysianVMU is there aren't any a complete lists of Dreamcast VMU emulators, and the emulators that can be found are poorly documentedemulator:[http://evmu.elysianshadows.com/ ElysianVMU]
