Something I have always wondered about is how to do smooth fast scrolling.

If we assume the game runs at 50 fps and scrolls one pixel per frame then it can scroll 50 pixels per second. At 50 fps it will take 6 seconds to scroll across the screen.

How do games do quicker scrolling?

Do they just scroll more pixels at one time? And where does AGA 1/4 pixel scrolling come in - can AGA scroll between pixels and wouldn't this be even slower????

Confused - I know I am!
