Hi i done a s-video mod on my sega genesis 2 and it works but when something white comes up on the screen, the screen rolls up.

Any other color like a dark color the scrren dose not roll up. I got my caps on the jack right and all is good so what is the problem?

If you know the anwser pls reply if you are not sure or dont know please dont waste my time. And no stupide anwsers like trolling or any other type of crap. all i want is to have a clean subject.

What video encoder is in it?

And why the paranoia of being trolled?

Becuase I had a lot of bad history thats why.
