For years, clever makers on the Sudomod forums have been building their own portable video game emulation consoles by putting Raspberry Pis into original Game Boy shells. What started with a lot of parts and soldering evolved into all-in-one printed circuit boards such as the Kite Circuit Sword. While Kite's brilliant Circuit Sword PCB takes a lot of the pain out of building your own Game Boy Zero, it still requires a substantial time investment, a knowledge of hobby electronics and soldering, and access to certain tools.

At howchoo, we've been teaching you how to build similar unique systems for years. Finally, we're excited to announce that a legitimate company has built what we've all wanted: a portable Raspberry Pi retro gaming rig in the form of a [slightly smaller] original Game Boy DMG-01.

Introducing the Retroflag GPi Case

Retroflag, the company behind many amazing Raspberry Pi cases and USB gamepads, is about to release the Retroflag GPi -- the first commercially-available Game Boy Zero.

Release date and price

As confirmed by Retroflag, the GPi Case will be released in the beginning of June at a cost of $69.99. We'll update this guide and make further announcements on our Facebook page as soon as it’s available. Because it is priced so low, we anticipate the first batch will sell out on the first day.

Don't miss out! We'll notify you know when the GPi is released.

The RetroFlag GPi will be released sometime in the beginning of June and the first batch is expected to sell out. At the request of a few howchoo users, we're going to send an email out the second it goes on sale on Amazon.

The GPi is an all-in-one unit that emulates retro video games on the tiny $10 Raspberry Pi Zero computer using the free RetroPie software library.

To build it, simply install RetroPie on a Raspberry Pi Zero W, insert the Zero into the included game cartridge, and slide it into the GPi case. Finally, add your own RetroPie ROMs.

That's it!

Retroflag GPi features

The GPi features many of the features of the original Game Boy -- including an internal speaker, DC barrel power jack, screen contrast wheel, volume wheel, headphone jack, and power switch. It also adds a few -- like easy external SD card access.

The unit features a DC barrel to USB cable that will power the unit without batteries. You can connect this to any 5V power source -- such as your computer's USB port, an AC adapter, or even a portable power bank.

It remains to be seen how well the unit will handle the power switch. A Raspberry Pi power button generally requires a software component to send a safe shutdown signal to the Pi.

The GPi comes with the case itself, a power cable, and a reversible screwdriver. You'll need to bring your own Raspberry Pi Zero W, micro SD card, and batteries.

At 135x81x32mm, the Retroflag GPi Case is slightly smaller than the Original Game Boy (DMG-01) — but is otherwise a faithful recreation.

Conspicuously present on the face of the device are new X and Y buttons, allowing you to play additional games from the Super Nintendo era onward. On the back, two shoulder buttons further cement the number of games you'll be able to play.

Gone are the days of waiting for the next street lamp to pass so that you could unpause and continue your game on a hellish green screen. The GPi features a full color IPS LCD display with a wider aspect ratio than the original Game Boy's. At 2.8", it's also noticeably larger than the original screen, despite the handheld itself being smaller.

The GPi screen resolution is 320x240. This is sufficient for playing retro games, which were designed for low-resolution displays to begin with.

The plastic looks identical, and the D-Pad and buttons also work brilliantly.

As far as quality goes, Retroflag got this right. As Nintendo Life reports, "the plastic looks identical, and the D-Pad and buttons also work brilliantly".

It's refreshing to see that Retroflag got these right -- cheap plastic and mushy, unresponsive buttons would be a dealbreaker for most.

Retroflag GPi power

The GPi is powered using three AA batteries, providing a total of 4.5V. Since the Raspberry Pi requires 5V to run, internal circuitry boosts this 4.5V to 5V. Boosting voltage decreases the total output amperage and, thus, the overall capacity (mAh) of the batteries themselves.

It remains to be seen how long you can play on these, but in any case I recommend picking up a set of rechargeable AA batteries to keep you going.

You can also connect a power bank to the GPi's power port to play on the go.

The GPi features an internal speaker as well as a headphone jack in the same location as the original. Of course, you can also output sound via bluetooth directly from the Pi to your bluetooth headphones or speaker of choice.

The speaker gets surprisingly loud and the sound quality is decent. There is a small amount of static present, but this can be fixed with some software tweaks inside the system itself.

Retroflag won’t officially release the GPi Case until the beginning of June, but when they do it will be available for purchase on Amazon.

As soon as the GPi is released, we will add links to purchase it here. You can also follow us on Facebook and we'll announce when it's available.

The Retroflag GPi Case is a solid, faithful recreation of our beloved DMG-01. It seems they've nailed every detail -- except maybe for power. It would be really nice to have a rechargeable internal battery rather than hauling around a bunch of primitive AAs.

And at just $69.99, this system is an amazing value. You'll still need to bring your own Pi Zero, SD card, and grab some rechargeable batteries, but even with those costs factored in, the GPi is well worth it.

Check back soon!

We'll add more details to this article as they become available. For more photos and coverage of the Retroflag GPi, check out the feature on Nintendo Life.
