Ikegami Tsushinki Co., Ltd.(JP) is a company that assisted Nintendo with the programming of several of their arcade video games. Although Ikegami wasn't formally given credit for the games they were involved in, they owned the copyright to the code they created for them.

Legal dispute[]

After the release of Donkey Kong Jr., the arcade successor to Donkey Kong, Ikegami sued Nintendo for the unauthorized duplication of the Donkey Kong program code.[1] Nintendo managed to settle the dispute out of court after the two companies came to an agreement. At the time of the suit, computer programs were not considered copyrightable material. The Tokyo High Court gave a verdict in 1989 that acknowledged the originality of program code. Ikegami and Nintendo reached a settlement the following year; the terms of it were never disclosed.[2]
