+description = "A port of the Cemu Wii U emulator to libretro. Renders through the frontend's hardware context, either Vulkan (sharing RetroArch's instance, device and queue) or OpenGL 4.5 core profile, and can composite the GamePad (DRC) screen next to the TV screen in several layouts. Save states are not supported and never will be, as Cemu has no infrastructure for serializing emulator state."
