→Libretro cores: Updated details from new blog post. Reicast regular requires OpenGL 3 and GLSL 1.30.
==Libretro cores==
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 2 3 and OpenGL ES 2 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.
===Supported GPU features===

*[https://www.youtube.com/watch?v=SShXk8l1NOs Trilinear filtering]
*[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.)
===Misc features and enhancements===
*Analog trigger and digital trigger simulations ([https://www.youtube.com/watch?v=9ZDQGAxTyL0 Analog controls] also work on NaomiNAOMI)
*[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)
===Supported platforms===
*Dreamcast
*Sega Naomi NAOMI and Atomiswave arcades
