You slightly underestimate the semi-cleverness of my flicker
algorithm but your point is valid.
(I don't do all Pterry, all Players on alternate frames...
if 1 = player 1, 2 = player 2, and T = Pterry, I do
1 2
1 T
1 2
T 2
1 2
etc: Pterry every 2, Players 3 out of every 4
Basically what you're saying to do is move my exact repositioning
routine to between the score and the action. I'd have to do it
at most once I think at the cost of 2 or so scanlines, since I
can put the score above each player, and then there's just a 1
in 2 chance I have to move one of the players to be Pterry.
It might be worth looking into...but I'm not sure, since I
think right now I have the ball bouncing off the 'ceiling'...
I'd have to be very careful about when I turn off the BGCOLOR
for that....
I'll take a look into it, though behind making Pterry movement
more interesting, dumbidfying the AI, tweaking the physics,
and fixing my title screen frame bug....

> So you'd position your sprites twice per frame which will cost you a scanline (maybe 2 depending upon how you're doing the positioning) but doesn't really require any new code - You should be able to do it all just by re-using some code and shifting around some code. All you should need to do is:
