* Multiple plus raster interrupts are used to make the shading in the sky
* Plus sprites are used for the Gremlin logo on the title screen (this actually overlays a smaller, software sprite Gremlin logo), and for extra colours and scenery in the game.
(Sprites are x2 in X and x1 in Y, which give a mode 1 equivalent pixel size)
* Plus screen split is not used
* Plus pixel by pixel hardware scroll is used.
