| − | 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.
