Scrolling backgrounds are formed using a set of sprites positioned directly next to each other. A sprite is only 16 pixels wide so many are needed to fill the screen horizontally. The Sticky_bit is often used to make this simpler. A set of 21 chained sprites can be used to make a single full-screen scrolling background layer.
