==History with the ''Mario'' series==

[[Hiroshi Yamauchi]] hired Ikegami Tsushinki to assist [[Shigeru Miyamoto]] in developing ''Donkey Kong'', as he had no programming experiences at the time<ref name="Gamasutra"></ref>. Miyamoto's would produce various ideas and sketches, that Ikegami would then program into the game.

The contract gave Ikegami exclusive rights for manufacturing ''Donkey Kong'' arcade boards. Due to the unexpected demand for the game, [[Nintendo]] ignored the clause and produced arcade boards of its own<ref name="Gamasutra"></ref>.

Nintendo later hired a company named Iwasaki Engineering to reverse-engineer ''Donkey Kong'''s code in order to produce [[Donkey Kong Jr. (game)|a sequel]]<ref name="Gamasutra"></ref>. In response, Ikegami Tsushinki filled a lawsuit for copyright infringement. In 1990, a court ruling decided that Nintendo did not own the arcade ''Donkey Kong'' code. The two companies settled out of court<ref name="Gamasutra"></ref>.
