REG_*MAIN registers are used for the top LCD, while SUB is used for the bottom LCD.
REG_*MAIN registers are used for the top LCD, while SUB is used for the bottom LCD. The registers for the main LCD is located at 0x1EF00400, while the sub LCD registers are located at 0x1EF00500.

This register might control the framebuffer dimensions, however writing to this doesn't affect the displayed LCD image.

The above framebuffer registers contains the physical address for each framebuffer, normally located in FCRAM in the application's GSP heap.
These LCD framebuffers normally contain the last rendered frames from the GPU. The color format is BGR8. The framebuffers are drawn from left-to-right, instead of top-to-bottom.(Thus the beginning of the framebuffer is drawn starting at the left side of the screen)
Both of the 3D screen left/right framebuffers are displayed regardless of the 3D slider's state, normally when the 3D slider's state is set to "off" the left/right framebuffer addresses are set to the same physical address.
