I recently bought a non-working Gameboy from eBay with the intention of hacking it to run RetroPie using a Raspberry Pi Zero. I chose a non-working Game Boy not only to reduce cost but also so that I wouldn't have to destroy an original, perfectly fine Game Boy.

The listing stated that it suddenly stopped working -- and when I received it, I noticed the battery terminals were extremely corroded, caked with a greenish residue. It seemed obvious to me that this is why it stopped working. This is an extremely common reason for these old Game Boys to not power on.

I plan on getting this one to work, keeping it, and then ordering another non-working Game Boy for my Raspberry Pi Zero emulator project (check back later as I'll be writing that guide here on howchoo).

For this guide, I'll show you how to clean your Game Boy's battery terminals, hopefully restoring your Game Boy to a working order.
