 Both run on modified "Crazy Climber" hardware, and in addition, there are other versions that run on "Scramble", Jeutel, Orca, and Alca hardware.The official "Crazy Kong" versions came in two different stand up cabinets that featured a large and angry, rather than comic, ape embedded in the artwork; they were manufactured by Zaccaria (also Italian distributor of the game).As Nintendo released "Donkey Kong Jr." (a "Donkey Kong" sequel), Falcon developed and published a cloned-sequel as well entitled "Crazy Kong Jr", also known as "Crazy Junior", but unlike the previous one, it was unlicensed by both Nintendo and Nintendo of America.
