/* Explanation of the magic behind ClearScreen:
|
|
|
|
There's numerous possible formats for the pixel data in the EFB.
|
|
|
|
However, in the HW accelerated plugins we're always using RGBA8
|
2010-12-21 22:18:40 +00:00
|
|
|
for the EFB format, which causes some problems:
|
2010-12-27 18:09:03 +00:00
|
|
|
- We're using an alpha channel although the game doesn't
|
|
|
|
- If the actual EFB format is RGBA6_Z24 or R5G6B5_Z16, we are using more bits per channel than the native HW
|
2010-12-20 16:57:29 +00:00
|
|
|
|
|
|
|
To properly emulate the above points, we're doing the following:
|
|
|
|
(1)
|
2010-12-21 22:18:40 +00:00
|
|
|
- disable alpha channel writing of any kind of rendering if the actual EFB format doesn't use an alpha channel
|
|
|
|
- NOTE: Always make sure that the EFB has been cleared to an alpha value of 0xFF in this case!
|
|
|
|
- Same for color channels, these need to be cleared to 0x00 though.
|
2010-12-20 16:57:29 +00:00
|
|
|
(2)
|
2010-12-27 18:09:03 +00:00
|
|
|
- convert the RGBA8 color to RGBA6/RGB8/RGB565 and convert it to RGBA8 again
|
|
|
|
- convert the Z24 depth value to Z16 and back to Z24
|
