This is one from the same seller I bought my csync NTSC SNES cable from. I'm assuming this should work fine? Looks like it uses composite video as sync.

Or this one, which claims to get csync:

It's possible that the 2nd one has a sync stripper in the cable (usually at the scart end) to clean up the composite line's sync. You could try messaging the seller and asking.
