How many grown-up hardware hackers whiled away their youth playing Tetris or Mario on their Game Boy? Fond memories for many, but unless you are lucky your Game Boy will probably be long gone. Not for [Gautier Hattenberger] though, he had an unexpected find at his parents’ house; his Game Boy Classic, unloved and forgotten for all those years. Fortunately for us his first thought was whether he could use it as a controller for a drone, and better still he’s shared his work for all of us to see.
Back in the day a would-be Game Boy hacker would have been deterred by Nintendo’s legal defences against game piracy, but with the benefit of a couple of decades the handheld console’s hardware is now an open book. Unfortunately for [Gautier], he seems to be the first to use one as a flight controller, so he had to plough his own furrow. His Game Boy Game Link serial port feeds an Arduino/FTDI combination that converts Game Link to USB, which is then sent to his laptop on which a small piece of software converts them to commands for the drone through the Paparazzi UAV framework.
All his code is in a GitHub repository, and he’s posted a video of his work which you can see below the break. For a child of the early ’90s, the mere thought that their handheld console could do this would have been mindblowing!
For being more than 20 years old, [Max]’s old brick-sized Game boy still has a lot of life left in it. Even though his Game Boy was still in good condition, there were a few vertical lines in the display, making it a perfect candidate for a restoration. While he had his DMG-01 open on his work bench, [Max] also decided to put in a back light.
After researching the blank vertical lines in his Game Boy’s display, [Max] learned the problem was probably a loose solder connection. [Max] whipped out his tri-wing screwdriver, disassembled his classic plastic friend, took a soldering iron to the LCD’s flex connector, and fixed the problem easily.
Since his Game Boy was already taken apart, he decided to add a 3rd party backlight. The installation was a snap – [Max] only removed the reflective LCD backing and shoved an edge-lit backlight panel into the Game Boy.
If you’re wondering why anyone would still be interested in a 20+ year-old Game Boy, the DMG-01 is highly regarded in the chiptune scene when paired with Little Sound DJ, in part because of the noisy amplifiers and unique sound. Anything that keeps these wonderful machines out of the garbage is alright in our book, so we’ve got to hand it to [Max] for putting together this wonderful tutorial.
