      I’ll test it with a monitor tommorow.
      Though where would I go about to get an already modified SCART cable for the SNES and PC Engine RX?

      Preferably ones that are compatible with the OSSC.

        Hey, I get the confusion, its an arcade monitor, so it accepts 15khz. Forgot to mention that. It’s currently wired to the H pin on VGA and displays fine on the monitor, just doesn’t get picked up on the OSSC. I can wire up a sync separator if it wants separate sync, I guess if LM1881 isn’t what I want, can you suggest an alternative?
        So you have genesis pin1 directly wired to VGA HSYNC pin, and it works on a monitor but not with OSSC using AV3 RGBS?

          Yes, it’s wired to HSYNC, and works on my monitor. I’m using AV3 with RGBS and it won’t display at all, strangely.

          Just checked again and… not sure how/why but my Sega actually just straight up stopped working. -_-
          I’m gonna have to get a new one… I’m sure it will work. Thanks for your help!

            Most likely just bad coincidence, but I’d be extra careful with that SYNC line since it comes directly from Genesis VDP without much of an ESD protection – hotplugging and such should be avoided.

              Thanks for the suggestion… Anything I can do to alleviate that?

                OK I got the European Scart cables, and now my SNES and PS2 now work fine.
                However, my PC Engine RX still doesn’t pick up any sync signal.

                Ok I got it, it was a switch in the back of the console to switch the video mode.
                Everything is working now.
