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. Paul J.
