func Refresh(data unsafe.Pointer, width int32, height int32, pitch int32)

Refresh the texture framebuffer

func Screenshot ¶

func Screenshot(path string) error

func SetPixelFormat ¶

func SetPixelFormat(format uint32) bool

SetPixelFormat is a callback passed to the libretro implementation. It allows the core or the game to tell us which pixel format should be used for the display.

func SetRotation ¶

func SetRotation(rot uint) bool

SetRotation rotates the game image as requested by the core
