Reply To: Snes screen distortion on top of the screen
It seems the info about the SNES on the wiki contains an error, suggesting to adjust coasting rather than loop gain (I had a feeling there was something off.)
I suspect there to be this mistake too.
The text quoted below describes exactly what happens when I increase Loop Gain. Post-Coast set to 1 would be a decrease from its default value on the OSSC Pro (4). A Loop Gain of higher than 1 indeed breaks compatibility with my capture card, while Post-Coast even at 4 does not. (And Post-Coast is supposed to be decreased to zero in the OSSC instructions.)
PLL bandwidth can be increased via “AV1-3 sync opt -> H-PLL Post-Coast“. Usually value 1 is enough to clear the jitter while preserving display compatibility. With higher values framelock may need to be disabled to ensure display can sync with the signal.
