Reply To: Sync problems with NTSC Sega Genesis


IIRC the OSSC has a built in sync filter and reccommends that you don’t use any external sync cleaner/boosters (in the cable for instance) as they can cause issues with the OSSC.

If the retro gaming cables cable is like the cable I got from retro_console_accessories on ebay it might have the in built sync cleaner/booster. Opening the cable and seeing what’s inside won’t hurt anything you know…

And AV3 RGBHV requires TTL level sync, AV1 RGB SCART does not it requires 1Vp-p 75Ohm terminated, so if it works in AV3 then the cable might be boosting the MD’s Csync output to TTL level which is why it cant lock to it on AV1.
