Right, exactly why I told him to make sure both 75ohm and sync was raw (not buffered or regenerated).It's not the LPF that makes a difference here, it's the sync level
I suspect he had it set to regenerated, and the OSSC was dropping sync not frames.
Long story short the HD15 port is designed with VGA input in mind, the Taito F3 work around is only that... A work around.
This is NOT how you should be running the average 15khz arcade PCB.
That's why I haven't sold this extra HD15 hat I've got... Once someone pops up and says "I need one for my Taito F3" I'll offer it to them.
