      Setting 480i/576i proc and 480p/576p proc to passthru. Then reduce H sync tolerance to as much as possible without getting a black screen(mine is 0.61). Never an official fix but this solves it for me

        It’s the PS1 cable from Retro Gaming Cables which contains the scart capacitors.

        I need to check but I think if it’s during the sequence it doesn’t happen it’s almost like theres an initial spike when you 1st turn the PS1 on.

          Thanks for taking time to look into this issue. I think the OSSC is a seriously great product and I love it, so I don’t mean any disrespect by saying that I think this is an issue with the OSSC and nothing else.

          Let me clarify the issue exactly.

          I only use PAL PS1 software but its irrelevant in regards to this, as the problem occurs if there is no game in the console.

          It’s not the display, my primary TV is an LG TV and once the shimmer has started to test I have moved the HDMI to my secondary Samsung TV and the shimmer still occurs.

          To fix I change the input on the OSSC then change the input back. This fixes the issue until the PS1 restarts. There are no shimmer effects reoccurring from 240p to 480i transitions.

          Turning the OSSC on and off also stops the shimmer effect and also turning the OSSC off once the shimmer effect has gone does not make it come back.

          There is only one place the shimmer effect occurs and that is if the OSSC is already on during PS1 boot/restart and the Sony Enternainment screen is displayed (White background and orange diamond). If you turn the OSSC on after boot the shimmer effect doesn’t happen.

          Something to note when the shimmer is occurring the OSSC shows 49.88Hz.
          After either turning the OSSC off and on, or changing input making it work fine again the OSSC shows 50.00Hz.
          (This is on the PS1 boot and menu screen that shows Memory Card and CD Player)

          I hope that clarifies everything and sorry if I’ve come across rude in anyway or misinformed.

          I’m hopeful there can be a firmware update that maybe could fix this issue but to be honest it’s no major gripe as it’s simple to remedy and will last until you restart the PS1.

              I also have this issue. Only way to fix is to change to another input and then go back to input1 (RGBS – AV1). This issue does not occur on PS1 games on PS2, only on PS1 so is not game specific.

              The Sony intial boot up logo causes the shimmer and then once its gone if you switch inputs it clears the problem.

              If you turn the OSSC on after the Sony logo has disappeared you don’t get this issue.

              I’ve had a playabout with the settings but nothing fixes other then switching to another input and switching back.
