, 02:28, 21 March 2009→EFB source registers: pretty new registers
===EFB source registers===
One can specify which part of the EFB is copied to the XFB or texture, using the following BP registers:
{{reg24 | GX_BP_EFB_BOXCOORD | addr = 0x49 | fields = 3 |
|4 |10 |10 |
|U |R/W |R/W |
| |Y |X |
|}}
* 0x49: coordinates to top left of rectangle in EFB that will be copied (packed format, unknown)
{{reg24 | GX_BP_EFB_BOXSIZE | addr = 0x4a | fields = 3 |
|4 |10 |10 |
|U |R/W |R/W |
| |height-1|width-1|
|}}
* 0x4a: width and height-1 of rectangle to copy in EFB (again, unknown packed format)
===XFB destination registers===
The destination of the copy in the XFB is specified by the '''physical''' address of the XFB and the row stride (basically width of row, but no scaling appled).
