Mappy

Mappy (マッピー, Mappī?) is a 1983 arcade game by Midway Games (until Namco Classic Collection vol.1 is released, it was made by Namco). In the United States, it was manufactured and distributed by Bally/Midway. Mappy is a side-scrolling platformer that features cartoon-like characters, primarily cats and mice. The game's main character itself is a mouse. Mappy runs on Namco Super Pac-Man hardware, modified to support horizontal scrolling. The name "Mappy" is likely derived from mappo, a Japanese slang term (slightly insulting) for a policeman.
