Golden Sun: The Lost Age Cheats

walk on water
At SW Atteka Islet, push the box off the cliff and save while on top of it.
Reset and go into your file again. You will be on the water and be able to
walk around in it.
(While testing this glitch, I noticed that if you push the box left 3 times,
up, then left, from it's original location, the fence above it messes up.
The fence that is now above it, can go on top of your character graphic.)

Why it works: When you save, the game stores your location and the location
of the box, but when you load the file, it doesn't record that you're on top
of the box. When the file loads it sends you down to a probable height.
