Ape Escape: On the Loose

To unlock Specter Boxing, collect twenty Specter Emblems. The characters are 1-Ton and John.

If the monkeys see you and jump into their UFO, equip your slingshot and shoot it down. If it falls, the monkey will be temporarily stunned.

There are certain mini-games that you can unlock by finding Specter Coins which are placed in a variety of places throughout the levels.

When you go to save the game, go to the view monkeys section (the floppy disk with a monkey on it). To view a monkey, you are instructed to press X, but instead you can also use Circle. Highlight a monkey and press either X or Circle. Move to the last monkey you have (you must have over two pages), then move back to the first monkey. There will be an "L" at the bottom left hand corner of the screen, but you cannot move back with L. To exit this glitch, press R once and when you press L it will be gone.
