Re: Screenshot
Split screen, and similar tricks, were very easy on systems such as the Commodore 64 due to the very useful and flexible IRQs. Changing everything about the display from the display data source and display mode to the background colours and the overlaid sprites allowed for some very useful techniques. It was very commonly used to separate vertical sections where one section was scrolled and the other was not - for example a status/score panel separate from the gameplay area.
