Page for flycast, fork of reicast which has standalone builds and an libretro core; shouldn't be longer relevated to an subsection in reicast due to the amount of differences and that it is no longer associated to reicast.

==Overview==
===Unemulated Features===
Regarding 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 />
''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 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. Can also show all 4 attached VMU screens at once.)
*Extra Depth Scaling (Fixes graphics in Samurai Shodown VI (NAOMI).)
===Misc features and enhancements===
*Analog trigger and digital trigger simulations ([https://www.youtube.com/watch?v=9ZDQGAxTyL0 Analog controls] also work on NAOMI)
*[https://www.libretro.com/index.php/reicast-libretro-now-supports-naomi-other-additions/ Fast GD-ROM Loading] (Cuts down virtually all loading times in games)
*Improved ADPCM decoding (Audio)
*[https://www.youtube.com/watch?v=FNTXZ5AmfiQ Floating point maths accuracy improvements] (Fixed broken enemy AI in ''Soldier of Fortune'')
*[https://www.libretro.com/index.php/reicast-libretro-updates/ EEPROM saving/loading implemented] (NAOMI)
*[[Shaders_and_Filters#Smoothing_shaders|xBRZ]] texture upscaling
*[https://www.libretro.com/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.)
===Supported platforms===
*Sega Dreamcast
*Sega NAOMI and Atomiswave arcades ([https://github.com/libretro/reicast-emulator/issues/136 NAOMI compatibility list] [OIT])
:- Supports both .DAT/.LST legacy ROMs, and latest MAME ROMs
