Turbo mode Recommended. The main idea is to take a sprite, and fill it in. How this works is it creates 300 clones, and gives each clone an ID. When the clone is created, it changes its y pos by 0 - (var) ID. Then, it uses the scanning system to scan its y level of the screen. Later on, the clones get re-used to cover the screen. That is a (brief) explanation on how this works.
