The '''[[wikipedia:Sega Dreamcast|Dreamcast]]''' is a sixth-generation console released by [[wikipedia:Sega|Sega]] in on November 27, 1998 in Japan and later on September 9, 1999 in NA. It retailed for {{Inflation|USD|199.99|1999 in other territories}}. 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 '''[https://segaretro.org/Sega_NAOMI [Sega NAOMI and variants|Naomi]]''', an arcade system board with similar components to the Dreamcast, is supported by some Dreamcast emulators. Sammy's '''[https://segaretro.org/Atomiswave Atomiswave]''' is an arcade system board that is was also based on the Dreamcast and Naomi.

Microsoft Sega collaborated with Sega for DreamCast Microsoft 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 wasn't mandatory to use and most developers opted for developers, but most games used Sega's proprietary software development tools instead out of convenience. This Even in major emulators, this aspect isn't implemented in all emulators(or implemented well).

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 fromWindows CE games emulation is still poor and slow.
