Donkey Kong 64: how to unlock every Kong, Jetpac, the coins and Hideout Helm
Quick answers for unlocking Diddy, Lanky, Tiny and Chunky, Jetpac, DK Arcade, the Nintendo and Rareware Coins, Hideout Helm and the B. Locker cheat.
Original 1999 Nintendo 64 release, which requires the Expansion Pak packaged with it. The 2015 Wii U Virtual Console release offers the same game; later remakes, mods and randomisers are outside this guide.
Diddy Kong
Free Diddy in Jungle Japes. DK must open his cage on the mountainside, after which Diddy joins and Tag Barrels let you swap between them.
Lanky Kong and Tiny Kong
Both are imprisoned in Angry Aztec. Explore the temples with DK and Diddy, using their instruments and moves, to reach the cages.
Chunky Kong
Chunky is the final Kong, held in a hanging cage in Frantic Factory.
Jetpac and the Rareware Coin

Collect 15 Banana Medals, then play Jetpac on Cranky's machine. Score 5,000 points to win the Rareware Coin.
DK Arcade and the Nintendo Coin
In Frantic Factory, use DK's Gorilla Grab on the arcade lever. Clearing the original Donkey Kong arcade game once gives a Golden Banana; clearing it again awards the Nintendo Coin.
Hideout Helm

Collect 100 Golden Bananas for B. Locker and shut down the Blast-o-Matic. The final key is behind doors that need four Battle Crowns and both the Nintendo and Rareware Coins.
B. Locker cheat
In front of B. Locker, press Up, Down, Left, Right on the D-pad. Then approach him as the Kong associated with that level to enter with fewer Golden Bananas (for example 50 instead of 65 for Crystal Caves with DK).
The coins are the usual reason a 101% file stalls: play Jetpac and the DK Arcade as soon as you have the medals and Gorilla Grab.
