      Hi

      I’m getting crazy input values when trying to sync my arcade Neo Geo MVS to OSSC. The LCD flickers between many numbers, but the photo I took says 2318i, 750.00kHz 647.10. Not very close to 15kHz…

      At first I had forgot to put 150 ohm on rgb and sync, but the result is the same after adding those. Have tried the h-sync option (8.30) but that does nothing. Otherwise it’s a pretty straightforward setup. Jamma to Neo Geo, video to Scart, +5V measuring 5.06 on PSU.

      Suggestions?

        yes, I do have a suggestion, this happened to me two days ago with my dreamcast ! Check every single cable if it’s correctly plugged in. I had the exact same thing (OSSC was displaying weird resolutions like crazy) and turns out it was my Toro box that wasn’t correctly plugged in.

          Ha! It seems I had forgot to route som power to pin 16 on the Scart. I get a ~15kHz signal now. Thanks!
