Donkey Kong 64
November 6, 1999
Donkey Kong 64 features the complete game Jetpac as an unlockable minigame.
It could be played in Cranky Kong's lab, and if players successfully got 5000 points, they would be rewarded the game's Rareware Coin. After taking pictures of 6 Banana Fairies, the player would be able to play it and Donkey Kong at any time by going to the Mystery Menu of the main menu.
Donkey Kong 64 was developed by Rare, that holds the rights for Jetpac, so they could freely include it in the game.
