The above framebuffer registers contain the VRAM physical address for each framebuffer.
The GSP module DMAs LCD framebuffers from the application's GSP heap located in FCRAM into VRAM. These 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)

The 3D screen left/right framebuffers are always displayed regardless of the 3D slider's state, when the 3D slider's state is set to "off" the framebuffer registers are set to the same VRAM physical address.
