It is unclear from the C-64 Prog. Manual, but it seems that the sprite
collision registers are only set once per scan (60 times a second for
NTSC versions).  If this is true, it means that a sprite can move no faster
than 60 pixels a second if you want to the detect when it hits the *edge* of
a background object of another sprite.

If this is true, how do some of those fast moving games get around this
problem?  

Please respond by mail and I will summerize to the net.
