'''reicast''' is an open-source [[Sega Dreamcast emulators|Dreamcast emulator]] produced currently for [[Androidemulators|Android]], Linux, and Windows. It is based on the source code of [[nullDC]] and nullDCe, existing Dreamcast emulators for Windows and Android, respectively.

==Overview== ===Unemulated Features===Regarding games with '''WinCE''' operating system functions and arcade games on the '''NAOMI 2''' machine (One of the latter variants of original NAOMI), [https://github.com/libretro/reicast-emulator/issues/136#issuecomment-427379382 someone] commented in a compatibility list page at reicast's GitHub repository in early October, 2018 (With edits):<blockquote><nowiki />''"WinCE requires SH4 MMU emulation, which is unlikely to happen in reicast as it will require a major rewrite of JIT/recompiler; plus few more hardware features, unused in DC/Naomi games - Maple at Vblank activation mode, Sort-DMA and maybe something else I forgot.'' ''Naomi2 will require ELAN T&L chip emulation. In Naomi2, display lists is input to ELAN as matherials, light sources, models, transformation matrices, etc; so, not like Dreamcast Tile Accelerator format.''You may open [[DEmul]]'s gpuDX11.dll using some PE resource editor, find there the PVR2_VSH (vertex shader file) which is mostly consisted of ELAN simulation."''</blockquote> ==Libretro corescore==Two reicast cores on [[libretro]] called '''Reicast reicast OIT''' and '''Reicast reicast regular''' were introduced [https://www.libretro.com/index.php/introducing-reicast-oit-libretro-core-updated-reicast-regular-core/ in June 2018] that replace the original core. These cores backport changes from [https://github.com/flyinghead/reicast-emulator flyinghead's fork] that rework the rendering system. The regular core is compliant with OpenGL 3 and GLSL 1.30 in order to support mobile devices and mid-tier PCs. The OIT core supports a graphics feature of the Dreamcast called Order-Independent Transparency that can only be properly emulated using OpenGL 4.3 and later, so it's only available for Windows and Linux at the moment.The two reicast cores have been merged in one '''reicast libretro''' core [https://www.libretro.com/index.php/reicast-libretro-and-reicast-oit-libretro-merged-into-one-what-you-need-to-know/ in October 2018]. In 2019 the core was first renamed to '''Beetle DC''' and a short while later '''Flycast''', for licensing reasons. ===Availability of versions===*Windows and Linux ([https://www.patreon.com/posts/reicast-libretro-20673851 32bit] and 64bit)*Mobile devices ([https://www.patreon.com/posts/reicast-libretro-20753597 Android OS and ARM hardware]. NAOMI arcade hardware also supported.)

*[[Shaders_and_Filters#Smoothing_shaders|xBRZ]] texture upscaling*[https://www.youtubelibretro.com/watch?v=utM62UMvqpM index.php/reicast-libretro-updates-26-7-2018/ Render to texture upscaling](Lets you set the upscaling factor to output whole screen at multiples of native resolution. Only affects games which render the screen to a texture, e.g. ''Dead or Alive 2'' or ''Crazy Taxi''. Results look amazing, ala what the xBRZ filter does to emulators for 2D-graphics consoles, e.g. SNES, GBA and etc.)

*Sega Dreamcast*Sega NAOMI and Atomiswave arcades([https://github.com/libretro/reicast-emulator/issues/136 NAOMI compatibility list] [OIT]):- Supports [https://github.com/libretro/reicast-emulator/issues/371#issuecomment-435695058 M2-keyed games] from MAME ROM sets (Has issues decrypting M1-keyed titles)
