Golf US Course competition
April 1, 1987
The Famicom version of Punch-Out!! was originally released in limited edition on a gold cartridge as a prize for a Golf US Course competition.
Specifically, 10,000 cartridges were made, with 5,000 of them given out to high scorers, 1,000 of them given randomly to competitors who got a hole-in-one, and 4,000 of them given randomly to competitors who had a 1, 2, 4 or 9 at the end of their ranking.
Copyrights for both series are held by Nintendo.
