Sales figures suggest Nintendo did pretty well with the Game Boy Color during its original run, even if the hardware and visuals feel a tad archaic and limited today. [Chris Hackmann] has taken the Game Boy Color design and reworked it from the ground up as the Frog Boy Color, kitting it out with modern upgrades in a GBA-like form factor while retaining the original hardware underneath.
[Chris] went to the wide-style GBA layout for comfort, which he considers superior to the original rectangular Game Boy format. He iterated through over 50 3D-printed enclosure designs to get the design to work, ensuring that the final housing could be CNC machined. He then set out to trim down the original Game Boy Color circuit layout to cut out hardware he considered unnecessary. The original LCD driver could go, since the Q5 replacement LCD he intended to use didn’t need it, and he also considered the IR port to be surplus to requirements. He also set out to replace the original audio amp with his own stereo design.
The result is a wide-format Game Boy Color with a gorgeous modern LCD, USB-C charging, and excellent compatibility with original games and accessories. Files are on Github if you want to build one yourself. Of course, he’s not the only person working on building the best Game Boy ever, but we always love seeing new work in this space. Video after the break.
If you didn’t grow up clutching Nintendo’s original DMG-01 Game Boy, it might difficult to see the appeal in 2023. It had the ergonomics of a brick, the system’s unlit LCD screen utilized a somewhat nauseating green color palette, and when compared to its contemporary competition like the Sega Game Gear or Atari Lynx, it would certainly appear to be the inferior platform. But despite its faults there was just something magical about the machine, and those who have a soft spot for the iconic handheld are always eager to relive those glory days.
The original Game Boy was the greatest selling handheld video game system of all time, only to be surpassed by one of its successors. It still retains the #2 position by a wide margin, but even so, they’re getting along in years now and finding one in perfect working condition might be harder than you think. What’s more likely is you find one that’s missing components, has a malfunctioning screen, or has had its electronics corroded by the battery acid from a decades-old set of AAs.
That latter situation is where [Taylor] found himself and decided on performing a full restoration on this classic. To get started, he removed all of the components from the damaged area so he could see the paths of the traces. After doing some cleaning of the damage and removing the solder mask, he used 30 gauge wire to bridge the damaged parts of the PCB before repopulating all of the parts back to their rightful locations. A few needed to be replaced, but in the end the Game Boy was restored to its former 90s glory.
This build is an excellent example of what can be done with a finely tipped soldering iron while also being a reminder not to leave AA batteries in any devices for extended periods of time. The AA battery was always a weak point for the original Game Boys, so if you decide you want to get rid of batteries of any kind you can build one that does just that.
After removing all of the components from the PCB, [Taylor] was quickly able to piece together what had happened. Despite the vigorous cleaning the game received after the spill, juice had found its way under each IC on the board. Left to sit in these nooks and crannies for who knows how long, the juice started to eat away at the traces on the PCB. Getting the game back up and running would naturally require considerable board repairs, but they don’t call him Solderking for nothing.
In the video below, you can see [Taylor] methodically scraping away the corrosion on the board before he starts recreating damaged connections with solid 30 gauge wire. Using tweezers and viewing the action through a digital microscope, he deftly bends the wire around to fit the shapes of the original traces and tacks the new conductors down with solder. He even goes ahead and repairs the traces that go to various test points on the cartridge; it’s a completely unnecessary extravagance, but we’re certainly not complaining. There’s a relaxing quality to watching him work, so we were in no rush to see his latest video end.
After fixing the board back up, he replaces all the components and takes it for a test drive on an original Game Boy Color. Confirming that Link’s 2001 outing is working as expected, he finishes the job with a few coats of spray-on conformal coating. With any luck, the next time this particular cartridge has to go face-to-face with some spilled juice, it will roll right off.
Standard cosplay is fun and all, but what is there for admirers to do but look you up and down and nitpick the details? Interactive cosplay, now that’s where it’s at. [Jaryd Giesen] knows this, and managed to pull together a working color Game Boy costume in a few days.
The original plan was to use a small projector on an arm, like one of those worm lights that helped you see the screen, but [Jaryd] ended up getting a secondhand monitor and strapping it to his chest. Then he took the rest of the build from there. Things are pretty simple underneath all that cardboard: there’s a Raspberry Pi running the RetroPie emulator, a Pico to handle the inputs, and two batteries — one beefy 12,000 mAH battery for the monitor, and a regular power pack for the Pi and the Pico.
As you’ll see in the build and demo video after the break, nearly 100 people stopped to push [Jaryd]’s buttons. They didn’t get very far in the game, but it sure looks like they had fun trying.
Since we’re still in a pandemic, you may want to consider incorporating a mask into your Halloween costume this year. Just a thought.
When we last checked in with [Bucket Mouse], he had just finished cramming a Game Boy Advance (GBA) SP motherboard into the body of the iconic Game Boy DMG-01, complete with an aftermarket IPS display. Unfortunately, after a few weeks of using the system, he ran into a few issues that sent him back to the drawing board.
This time, he’s revamped Nintendo’s classic handheld with the internals from its successor, the Game Boy Color (GBC). Obviously that means this new build can’t play any GBA titles, but that was never actually the goal in the first place. It might seem obvious in hindsight, but owing to their general similarity, it ended up being far easier to fit the GBC hardware into the Game Boy’s shell. Though we still wouldn’t call this an “easy” swap by any stretch of the imagination…
Whether you want to follow his footsteps towards portable gaming bliss or just want to live vicariously through his soldering iron, [Bucket Mouse] has done an absolutely phenomenal job of documenting this build. While he cautions the write-up isn’t designed to be a step by step instructional piece, there’s an incredible wealth of information here for others looking to perform similar modifications.
The build involved removing much of the original Game Boy’s connectors and controls, such as the volume wheel, Link Port, and even headphone jack, and grafting them onto a GBC motherboard that’s been physically trimmed down. At a high level it’s not unlike the trimmed Wii portables we’ve seen, but made much easier due to the fact the GBC only used a two-layer PCB. It also helps that [Bucket Mouse] has once again used an aftermarket IPS display, as that meant he could literally cut off the LCD driver section of the GBC motherboard. Of course there have also been several hardware additions, such as a new audio amplifier, power regulation system, LiPo charger, and 2000 mAh battery.
There’s a lot of fantastic details on this one, so if you’re remotely interested in what made the Game Boy and its successors tick, we’d highly recommend taking the time to read through this handheld hacking tour de force. His previous build is also more than worthy of some close study, even if it ended up being a bit ungainly in practice.
The Game Boy DMG-01 is about as iconic as a piece of consumer electronics can get, but let’s be honest, it hasn’t exactly aged well. While there’s certainly a number of games for the system that are still as entertaining in 2021 as they were in the 80s and 90s, the hardware itself is another story entirely. Having to squint at the unlit display, with its somewhat nauseating green tint, certainly takes away from the experience of hunting down Pokémon.
Now on the surface, this might seem like a relatively simple project. After all, the GBA SP was much smaller than its predecessors, so there should be plenty of room inside the relatively cavernous DMG-01 case for the transplanted hardware. But [The Poor Student Hobbyist] made things quite a bit harder on himself by deciding early on that there would be no external signs that the Game Boy had been modified; beyond the wildly improved screen, anyway.
That meant deleting the GBA’s shoulder buttons, though since the goal was always to play older games that predated their addition to the system, that wasn’t really a problem. The GBA’s larger and wider screen is still intact, albeit hidden behind the Game Boy’s original bezel. It turns out the image isn’t exactly centered on the physical display, so [The Poor Student Hobbyist] came up with a 3D printed adapter to mount it with a slight offset. The adapter also allows the small tactile switch that controls the screen brightness to be mounted where the “Contrast” wheel used to go.
An incredible amount of thought and effort went into making the final result look as close to stock as possible, and luckily for us, [The Poor Student Hobbyist] did a phenomenal job of documenting it for others who might want to make similar modifications. Even if you’re not in the market for a rejuvenated Game Boy, it’s worth browsing through the build log to marvel at the passion that went into this project.
