PPC

Libretro cores

Two reicast cores on libretro called Reicast OIT and Reicast regular were introduced in June 2018 that replace the original core. These cores backport changes from flyinghead's fork that rework the rendering system. The regular core is compliant with OpenGL 2 and OpenGL ES 2 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

  • 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.)
  • 64-bit dynarec (Fixes Shenmue 1/2, Marvel vs. Capcom 2 and Heavy Metal Geomatrix)
  • Flat shading and bump-mapping
  • Trilinear filtering

Misc features and enhancements

  • Analog trigger and digital trigger simulations (Analog controls also work on Naomi)
  • Fast GD-ROM Loading (Cuts down virtually all loading times in games)
  • Improved ADPCM decoding (Audio)

Supported platforms

  • Dreamcast
  • Sega Naomi and Atomiswave arcades
