    Both these systems seem to be broken in firmware 0.71. The LCD will display the correct frequency sometimes, other times crazy values like 794i. Even when the correct values are shown the OSSC will not sync.

    Edit – Tried all the way back to 0.67 Rel firmware and still the same problem.

    Temporary workaround for these issues:-

    1) Connect the console/computer via the AV3 input (D-Sub15/VGA). To do this you will need a suitable adapter. Separate sync is not required so any passive SCART to VGA should work.

    2) For the C64, set H-PLL Pre-Coast to 4 and H-PLL Post-Coast to 4.

    AV3 input requires TTL-level c-sync, so a passive SCART->VGA adapter is not necessarily enough.

    Ah right my bad, all my setup is wired for c-sync/clean sync, it is true.

    Update – C64 works when connected to AV1 if analogue sync LPF is set to max.
