Hacker International was a Japanese video game company that developed and published games from 1990 to 2001 for the Nintendo Famicom (including Famicom Disk System), NEC PC Engine (including PC Engine CD), Sony PlayStation (as Map Japan) consoles, and Microsoft Windows PCs.
[1] Many of their games were developed by Taiwanese companies and were released in non-pornographic form elsewhere in the world; however, three were released in the United States for the Nintendo Entertainment System with pornography intact (albeit sometimes modified to "Westernise" the girls' features) by another Taiwanese company, Panesian.
The Hacker name was first used by Satoru Hagiwara, an entrepreneur and former music producer, for a monthly PC magazine.
[2] Hacker International was founded by Hagiwara as an outlet for its writers' ideas; its first product was the Hacker Junior, an upgrade for Famicom systems that provided composite video output and turbo controllers, for which they were sued by Nintendo and eventually settled out of court.
[2] Hacker's relationship to other Japanese adult console game producers of the era, such as Super Pig and MIMI Pro, is debated.
