      Hello,

      I want to install the Dejitter mod on my SuperCiC’d PAL 1Chip-01 SNES, since my display is constantly losing sync in 60Hz mode. The available installation instructions all cover NTSC boards only. Additionally I want to use it together with my SuperCIC chip.

      Here’s a picture of the back of my SNES PCB: https://i.imgur.com/tZunJYJ.jpg

      Anyone able to help? Thanks in Advance!

        Ok passing this information on since I chased up my friend for it, hope it helps:-

        Here’s the info for installing de-jitter on PAL SNES with SCIC. It’s been a while since I installed one of these, hope I haven’t forgotten anything.

        Remove X1, C3, R28 and D1 from SNES motherboard.
        Leave JP2 open
        Leave JP3 open
        Connect 5v and GND to regulator output or any other 5v and GND points.
        Connect MCLK_EXT_i to SCIC clock output
        Connect CSYNC_i to pin 7 of S-RGB chip or any via connected to that pin.
        Connect MCLK_o to left hand through hole of X1 (TC1+)
        Connect CSYNC_o to top pad of R28
        Connect CLK_SEL_i to SCIC mode pin

            I think I have everything down besides:

            Connect CLK_SEL_i to SCIC mode pin

            SCIC mode goes to pin 111 of S-­CPUN. Do I keep this connection parallel, so SuperCIC mode goes to 111 and CLK_SEL?

            EDIT: connected it parallel, that was the only way it made sense, thinking about it. Thanks for the help, everything works perfectly!

              Aha, just found this whilst looking at what to do with my 1chip Super Famicom, it has a SuperCIC board installed and a borti designed RGB bypass with CSync and I’ve been looking for how to install the dejitter board I purchased a while back.

              Will crack open my console and see if this will work with also.

                There is no way of seeing this on pictures or any video? Thanks!
