Missing shadows #2

Open furrtek opened 1 year ago

Particularly noticeable and annoying in TMNT's sewer stage 3. Must be something with the k051962 or layer mixing.

This is the fix for shadows: https://github.com/paulb-nl/Arcade-TMNT_MiSTer/commit/08cc854d57072bb70de9b29323c5d64afb963117

Shadow buffer Q output was registered so output was 1 cycle too late for AK196/AK154 latch.

Shadows are working but the brightness needs tweaking. I think they are too dark.
