Hopper Robo

Hopper Robo is a platform arcade game, which was released by Sega in 1983; it utilizes a Zilog Z80 microprocessor (running at 3.072 MHz), with a General Instrument AY-3-8910 running at 1.5 MHz for sound. The player must use a two-way joystick to take up control of a robot (the eponymous "Hopper Robo"), and a single button to make him jump - and his objective is to collect the numbered boxes on each round in numerical order (the one he is supposed to collect next will flash), then drop them onto one of the two conveyor belts at the bottom of the screen. However there are several kinds of enemy robots that guard some of the boxes; they all move in preset patterns and you will have to learn their movements in order to figure out the best moment to sneak past them, because if any of them touch Hopper Robo they will drain some of his energy. If Hopper Robo should run out of energy, it will cost him a life - but when he clears a round, his remaining energy will be awarded to the player, as bonus points. It's also worth noting that this game runs on the same hardware as Orca's Marine Boy, which was released in the previous year, and is not related to the 1969 anime television series of the same name; the player took control of a diver who swam underwater rescuing mermaids and avoiding fish.
