These registers are used by [[GSP_Shared_Memory|GX command]] 3 and 4. For cmd4, *0x1EF00C18 |= 1 is used instead of just writing value 1. The dimensions fields seem to use the same format as [[LCD]] register 0x1EF00X5C. The framebuffer width in the dimensions fields' low u16 is 480 for the main screen, and 240 for the sub screen.
