Ultra Games
Ultra Software Corporation was a shell corporation and publishing label created in 1988 as a subsidiary of Konami of America, in an effort to get around Nintendo of America's strict licensing rules in place at the time for the North American market. One of these rules was that a third-party company could only publish up to five games per year for the Nintendo Entertainment System in the US. Nintendo's licensing was inconvenient for Konami, which had begun releasing more than ten games a year for both the Famicom and its Disk System add-on in Japan.
