A lot of animated graphics sequencies was created for the game. Animated sprites of the hero and enemies are mixed with backround using an accelerator. The number of actually available elements of backroung is higher what can be loaded in video ram at once, because the elements are reloading in realtime. The combined sprites are used for the hero (a bag for the diamonds is a separate sprite).
