Taito Corp released Jungle King in 1982. The game’s hero was a Tarzan like character that the estate of Edgar Rice Burroughs objected to and subsequently sued Taito for.
The company then revamped Jungle King replacing the offending character with an explorer and called it Jungle Hunt. Jungle Hunt eventually went on to be ported to most home consoles and computers of the 80’s.
Not satisfied with Jungle Hunt Taito continued to modify jungle King and came up with Pirate Pete. There were some minor game changes in Pirate Pete but the over all game play was Jungle King at its core.
