Sorry, that's what I was thinking.

But sprite flicker is kinda the same thing. Example, that polo demo(I
don't remember the name). I can't find it(I don't remember if I have a
copy), but IIRC, it does flickered venitian blinds. Isn't this the same
thing as the frame flicker of a tv image? I mean it is every other line
drawn on oposite frames. The only difference I see is that the lines on
the VCS are double height(in spaceing). And the polo demo's flicker is
obvious.

That is true, and the images are more continuous through the lines, but
what about the polo example?

Really? I mean in interlaced mode, shouldn't it be doing the same as a tv
signal? I've use a character generator that had very obvious pixals, one
per line, and it does not appear to flicker.

Nope, your right, it doesn't work. Well, it doesn't hold the frame, it
scrolls quite abit...
