Wacky Races

Wacky Races is a platform & game which was originally developed by Enigma Variations and released by Hi-Tec Software upon the Commodore Amiga in 1991 but was later redeveloped by PAL Developments for the Sinclair ZX Spectrum, Amstrad CPC and Commodore 64 (the last version was released by Rave) in 1992; it's based on the Hanna-Barbera cartoon series of the same name, which originally aired upon US television in 1968, and begat two spin-offs, Dastardly and Muttley and Their Flying Machines (also known as Stop That Pigeon) and The Perils of Penelope Pitstop, the following year. It was also the only Hi-Tec H-B game which had its 8-bit versions released after the 16-bit one.

And now, here are the most dare devil group of daffy drivers to ever whirl their wheels in the Wacky Races, competing for the title "World's wackiest racer." Take the part of Dick Dastardly, the master of villainy and with your unfaithful dog Muttley in this Wacky Computer Game Race. © Hanna-Barbera Productions Inc. 1991

Although all ten of the other Wacky Racers were present in the original Commodore Amiga version of the game, only the Slag Brothers (1), Peter Perfect (9) and Rufus Roughcut (10) are in the 8-bit ones.
