This sets GSP state for the LCD framebuffers, and other state as well. When the value of [[LCD]] register 0x1EF00X54 is >0x54, the GSP state for the specified screenID is immediately written to the LCD registers. This command should only be used when directly writing to the framebuffers, otherwise when rendering to the framebuffers with the [[GPU]] the framebuffer info stored in [[GSP_Shared_Memory|GSP shared memory]] should be used instead.
