Top Cat

Top Cat (full title: Top Cat in Beverly Hills Cats) is an action game which had been developed by PAL Developments and Twilight for Hi-Tec Software, and released upon the Sinclair ZX Spectrum, Amstrad CPC, Commodore 64, and Commodore Amiga in 1990; it is based on the Hanna-Barbera television series of the same name (which aired on US television from 1961 to 1962, and renamed Boss Cat when it initially came to the United Kingdom, due to a cat food that had that same name).
