Catch Monkeys without the RC Car
There is a simple way to catch monkeys without the use of the RC Car. This is a huge time saver as you don't have to wait unti the end of the game to get the RC Car. All you need is the Slingback Shooter and one flash bomb. Here's what you do. Switch to first person veiw with the slingback shooter and fire away at the money until it runs to one of those little cracks. Then switch to the flash bomb and nail him. Run over to him fast and equip your net. Grab him and poof that's it. That's all you have to do. It may take a bit of practice but when you learn it it really helps.

Hidden Mini-Game Boxers
You can get extra boxers on the Specter Boxing minigame by defeating them on Championship mode, although you'll have to run through it multiple times to get ALL of them.

Peak-Point Matrix
To get to the secret board in Ape Escape, you must beat Specter at the Level Monkey Madness (the carnival), wait to the ending finishes (including the credits), and then when the game gives you the option, go back to the Time Station and save your game. Then, go to all the levels, and finish catching the Monkeys you missed. When you catch every Monkey, the Peak-Point Matrox will open up, where you will get to fight Specter for the last time, and finally catch him. Then, you'll see the true ending.

Save A Life
When you fall off a cliff, press START and choose EXIT.
Then you will go to the time station with the same amount of lives before you fell of the cliff.
