Cxbx-reloaded: Failing pixel shader conversions

[PatrickvL]

Some titles log messages indicating pixel shader conversion failure, messages like:

[0x049C] WARN: Could not create pixel shader
[0x049C] WARN: (Statement 5) (Validation Error) Invalid dest reg num: 4. Max allowed for this reg type is 1.
(Statement 6) (Validation Error) Invalid dest reg num: 4. Max allowed for this reg type is 1.

Titles that show this:

• Raw 2

TODO: add more

For this issue, investigate fixes to get those shaders compiling successfully. (It might not be possible under Direct3D 8, but 9 should suffice)

Do you can create test-case for it? Or it is unnessesary?

Games will do

I think this Japanese title has it with a different message:

• J Phoenix+

[15B8] WARN: Trying fixed or recompiled programmable pipeline pixel shader!

---

• Metal Gear Solid 2: Substance

Received Fatal Message:

* Unknown PushBuffer Operation (0x1E60, 1)

You replied:

1E60 seems to be NV097_SET_COMBINER_CONTROL, possibly a pixel shader related modification done from within the push buffer command stream

Should those games that pop up the pushbuffer messages/warnings be a part of this issue?

Edit (April 2020):
Fixing this issue could fix the graffiti menu glitch in Jet Set Radio Future (old problem mentioned there in September 2018).

I think Sega GT Online has this problem too.
