This is a fairly meaningless question. The answer is, as fast as you want to scroll 'em. Scrolling depends on frame rate (which on the 2600 is 50/60fps) and upon your BG update - which can be from 40 pixels/frame (ie: one screen/frame - any higher is fairly meaningless) way down to 1 pixel every eternity. Basically, you will get any speed you want, because scrolling playfield graphics is not really the limiting factor. There is no hardware scroll, if that's what you're asking. You have to do it all manually by changing what you write to the PF registers.
