Behold: The Lego Game Boy has already been modded to play games for real

Today, the Lego Game Boy officially goes on sale. It’s surprisingly good. But in Australia, one woman has already created a more amazing version. Natalie the Nerd, the self-taught circuit board designer and Game Boy modder whose gorgeous transparent Game Boy we featured in August, is doing what Nintendo and Lego didn’t: make it playable.

Let me be clear: this is not an emulator. Natalie did not stuff a Raspberry Pi in here. It’s far more impressive than that. What you’re seeing are real Game Boy cartridges, running on real Game Boy chips, soldered to a real circuit board of Natalie’s own creation. Working buttons, too.

To fit it into the Lego Game Boy, she had to create a complete Game Boy board smaller than a Game Boy cartridge itself — so she did. Adding “the smallest screen kit on the market” did require removing a few bricks, though, she tells The Verge.

It’s not complete — not just yet. The working buttons, for instance, aren’t yet mounted on a PCB; she tells The Verge they’ll fit on a custom 3D-printed Lego piece.

She’s already wired up USB-C for power:

And here’s a look at the insides and where they live:

Now, to answer your obvious question: is this a one-off, or something you might be able to do yourself? The chances are good that you might if you’re skilled! Natalie sells aftermarket components for Game Boy modding, shares circuit board designs, and is planning to share this too. “I am going to release it once I am happy with it,” she writes on X.
