Nintendo Game & Watch: Donkey Kong

The clamshell Multi Screen Game & Watch is the clearest ancestor of the Nintendo DS: two LCDs in a case that opens like a compact. Donkey Kong, released in June 1982 in this orange case, also debuted Nintendo's cross-shaped directional pad, at bottom left, the control that went on to become standard on gamepads. Mario dodges barrels on the lower screen and climbs to the upper one, with the jump button on the right.
