[Kite] has been making custom PCBs for GameBoys for a long time. Long enough, in fact, that other people have used his work to build even more feature-rich GameBoy platforms. Unfortunately some of their work had stagnated, so [Kite] picked it up and completed a new project: a GameBoy that uses a Raspberry Pi running on his upgraded GameBoy PCB.
At its core the build uses a Raspberry Pi 3, but one that has been shrunk down to the shape of a memory module, known as the Compute Module 3. (We featured the original build by [inches] before, but [Kite] has taken it over since then.) The upgrade frees up precious space in the GameBoy case to fit the custom PCB that was originally built by [Kite], and also eliminates the need to cut up a Raspberry Pi and solder it to the old version of his PCB. The build is very clean, and runs RetroPie like a champ. It has some additional features as well, such as having an HDMI output.
For anyone looking for that retro GameBoy feel but who wants important upgrades like a backlit color screen, or the ability to play PSP games, this might be the build for you. The video below goes into details about how it all fits together. If you’re looking for more of a challenge in your GameBoy hacks, though, there’s an ongoing challenge to build the tiniest GameBoy possible as well.
