Carefully hinge unit so the screen half is face down on your desk with the circuitry portion sticking vertically upward. There’s a fairly short ribbon connector connecting the screen half of the Gameboy to the circuitry half. Once you take those screws out, don’t pull the Gameboy apart quickly. There’s four obvious ones on the back of the Gameboy, and two inside the battery compartment. It’s not super difficult, but you definitely want to be careful to avoid stripping the screws. If you don’t want to spend a couple dollars on a triwing driver, you can do what I did and use a small flathead in one of the three slots in the screws.
Triwing screws, for those of you unfamiliar, are Nintendo’s favorite way to make opening their products just ever so slightly more irritating. There are six screws, and depending on when your Gameboy was made, they are either going to be triwing or phillips. The first step is to remove the back cover of the DMG.
