How to clean a Game Boy game

I have never opened a Game Boy game before, and since I just won a lot of a few titles, I figured it needed to be attempted.

Step One: Completely remove the screw from the back. Unfortunately it does not work like the NES where you can unscrew it all the way but leave the screw in. If you don't take it all the way out, you can't continue.

Step Two: Turn the game over and push the top panel downwards as pictured above. Then you will lift the top of the game off.

Step Three: Clean as you would your NES with a pink eraser. As you can see, this game does not require any cleaning as it looks like it's never been used. Thankfully pretty much all the Game Boy games I got were like that.

As you can see, you do not need to turn it over and clean the other side like a NES game as there are no pins on the other side.

Step Four: Put the game back together, and you're complete!

So above are the games I won from ebay. It includes NES Play Action Football, Battletoads, Duck Tales, Godzilla, Gargoyles Quest, Mega Man: Dr. Wiley's Revenge, and Tetris. I paid a little less than $15.00 for the bunch including shipping. I have played Mega Man: Dr. Wiley's Revenge as a kid and I'm pretty sure most people who ever played a Game Boy has played Tetris on it. The rest of the games I have never played before. I looked at Godzilla only because I've seen a revew of it, but that's it! They all are in really nice condition. Time to play them all!
