How Do I Fix A Wet Gameboy Advance Game?

Let it air dry. Clean the connections with a q-tip dipped in alcohol, not saturated. Hopefully whatever liquid spilled in it didn't get inside the game. Give it a day or so. Don't use heat or put it in the sunlight to dry. That is unless you dropped it in the toilet or a bucket of water. At that point it might be a complete loss.

You could let it air dry then try it in your game if it doesn't work if u have a repair thing at your local game stop go there and they will give u a new one sorry if u had a BIG record on it and u lost it :(

You can either have a repair guy fix it or else throw it out and get a new one.
