I agree! It’s extremely difficult to discover the right h.samplerate for optim mode. The MVS optim settings have been discovered and are available here and they look great:

I tried to do Espgaluda by trial and error (no test pattern available on the PCB that I know of) and this was as close as I got but there is a wavy pattern through the background as it scrolls vertically:

Line5x mode 512×240 optim.
h.samplerate 680
h.backporch 67
v.backporch 13

Sampling phase on the other hand doesn’t seem so difficult to do by trial and error.

I’m trying to figure out the right way to determine h.samplerate here:
