Knowing that a court battle lay ahead, Hadl contacted Rissman, the errant Tiger licensee, to compromise on the handheld "King Kong" game. Hadl wanted to remove the exclusivity provision of the license and to distinguish the handheld game from "Donkey Kong" so as to weaken any potential counterclaims that one of Universal's licensees had violated Nintendo's intellectual property rights. Rissman complied, giving the hero a fireman hat, replacing barrel graphics with bombs, and making the game platforms straight instead of crooked. This design was approved in early June.
