    Thanks for the feedback, appreciated. I will try luma for the C-Sync line and also composite for C-Sync too and see if there is any difference on the SNES.

    YES ; S-CPUN pin 151 connects to pin 7 of the S-RGB chip.

    Thus, modern RGB bypass mods applied to a PAL SNES 1-chip can utilize buffered c-sync on pin3, so long as you have also free'd pin 3 from its 12v rail.

    Normally people use NTSC SCART RGB cables these days for any bypassed SNES 1Chip consoles, which uses sync on pin 3.
