Description[edit]
This sets GSP state for the LCD framebuffers. When the value of VCount (offset 0x54) is greater than a certain constant, the GSP state for the specified screen is immediately written to the LCD registers. This constant is 0x52 on GSP for 11.16.0-48, though it used to be 0x54.
This command should only be used when directly writing to the framebuffers; when using the GPU the framebuffer info stored in GSP shared memory should be used instead.
