For the NES? King Kong
There is a King Kong 1 for Atari 2600 though
for the Atari 2600 was made by TigerVision and was based off of the original King Kong
movie; Konami had nothing to do with the game, nor did they make any games based off of the original King Kong
This game, along with the quite different game Konami made for the MSX, is based of the King Kong Lives
movie which was released as King Kong 2
in Japan. This is not only clear from the original Japanese manual and box, but also from the gameplay itself which deals with Lady Kong from the King Kong Lives
movie, who was not present in the original movie.
