Fix HDMI timings #1

Closed sy2002 closed 2 years ago

sy2002 commented 2 years ago

Just as an internal reminder for not forgetting the TODOs: In the gbc4mega65 project, we are currently fine-tuning the HDMI video and audio compatibility. The results of these three issues need to be ported to the MiSTer2MEGA65 framework, too:

HDMI protocol analyzer complains about: "Invalid combination" Q1/Q0, Y1/Y0, YQ1/YQ0

720p @ 60 Hz CEA-861E Video Format Timing Error

Question: Is there an easy transistion?

The "Fix HDMI timings" part of this issue is done by the merge mentioned above. What is still missing is HDMI audio.

What is still missing is (outside of Audio, which will be done separately):

Bring this in sync with gbc4mega65's activities between July and November 2021:

Double-check the final values in commit 9e7b915e1b898865a1155789aadb9d39f4330797
Replace Scott's VGA timing generator by Adam's timing generator
Make sure we are not using hardcoded values but well-defined constants for the timing generator (double-check gbc4mega65 as well)

Done and double-checked on March, 28.
