Sega - Dreamcast (Redream)Link

BackgroundLink

Redream is a work-in-progress SEGA Dreamcast emulator written in C for Mac, Linux and Windows.

RequirementsLink

This core requires OpenGL 3.3 or higher in order to work.

RetroArch's video driver must be set to OpenGL. Go to Settings -> Driver. If the ‘video driver’ is set to something else or than 'gl', switch to ‘gl’, and then restart.

Attention

There is currently no ‘working’ macOS version available. This is because this core requires OpenGL core 3.3 context, and RetroArch on macOS currently does not support this.
