After the release of the original arcade game in 1988, the game was converted to most of the game consoles and home computers of the time. Most home releases came in 1989, with some arriving later through 1990–1992. The home computer versions were published by Ocean Software, and their home computer versions refer to Wally as a walrus on the packaging; however, the original arcade version specifically mentions him as being a leopard seal during the closing credits. The NES version was developed by Software Creations and published in the PAL regions by Ocean. In North America the NES version was published by Taito as Kiwi Kraze, instead of "The NewZealand Story". The game received more publicity due to being included in the Amiga 500 Batman Pack, which was launched in September 1989 and sold over 2 million units. Home conversions generally received good reviews in video game magazines. The game was also converted for the Japanese FM Towns and Sharp X68000 systems, providing arcade-perfect conversions, but released exclusively in Japan since both computers were only available there.
