'''reicast''' is an open-source [[Sega Dreamcast emulators|Sega Dreamcastemulator]] emulator produced currently for devices based on the ARM architecture[[Android emulators|Android]], Linux, Windows, including those running Android Switch and variations of LinuxPlayStation 4. It is based off on the source code of [[nullDC|nullDC]] and nullDCe, existing Dreamcast emulators for Windows and Android, respectively.

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 core==Two reicast cores on [[libretro]] called '''reicast OIT''' and '''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.) ===Supported GPU features===*Tile clipping support*Fogging support*Volume modifier shadow support*Multipass rendering (enabled by default for non-OIT)*Render to texture buffer*Log 2 depth buffer*Order independent transparency ('''OIT''' only)*Two-volume mode support ('''OIT''' only)*Accumulation Pixel Buffer Size core option ('''OIT''' only. Can be set to 512MB, 1GB or 2GB, depending on how much VRAM your video card has. May help with correct output at higher resolutions.)*[https://www.libretro.com/index.php/reicast-libretro-updates-shenmue-12-now-runs-plus-reicast-hackathon-event-july-6-8-switzerland/ 64-bit dynarec] (Fixes ''Shenmue 1/2, Marvel vs. Capcom 2'' and ''Heavy Metal Geomatrix'')*[https://www.youtube.com/watch?v=YWqxydgUe-U Flat shading] and [https://www.youtube.com/watch?v=_4TU7juoiNs bump-mapping]*[[Texture_filtering|Trilinear filtering]] ([https://www.youtube.com/watch?v=SShXk8l1NOs Video])*[https://www.youtube.com/watch?v=cH53fynF-N0 Improved palette/YUV texture quality] (Converts to 32-bit colors instead of RGB565; i.e. lossless quality of background textures in ''Alone in the Dark: The New Nightmare'' and is equal to DEmul and redream.)*[https://www.libretro.com/index.php/reicast-libretro-progress-report/ Display VMU screens in-game] (Positioning, opacity levels and sizing available.

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.) ===Supported platforms===*Sega Dreamcast [https://gamedb.reicast.com/games Compatibility list]*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) [[Category:Emulators]][[Category:Sega Dreamcast emulators]][[Category:Windows emulation software]][[Category:Linux emulation software]][[Category:PlayStation 4 emulation software]][[Category:Switch emulation software]][[Category:Pandora emulation software]]
