A creator has made Lego’s non-playable Game Boy set playable

When Lego announced its near 1:1, 421-piece Nintendo Game Boy set I wrote that it was charming, but “sadly not playable.” Now that it has started shipping (as of yesterday), creator Natalie the Nerd proved me 100 percent wrong. She added the power to play genuine Game Boy cartridges, using real hardware and not an emulator, according to her post on Bluesky and a story on The Verge.

The project was right up Natalie’s alley as she specializes in circuit board design, having even created a transparent one for another Game Boy project. To make the Lego Game Boy run, she created a custom circuit board with Game Boy chips soldered on, including working buttons. She then added the “smallest screen kit on the market,” she told The Verge, removing a few bricks to make it fit. You won’t even have to worry about batteries as it has a USB-C port to run everything.

It’s fully functional but not quite complete — on Bluesky, Natalie pointed out that the A and B keys are currently held in by an elastic band. To fix that, she plans to 3D print a lego piece that will hold a custom PCB for the buttons. Once it’s all ready, she’ll share her designs as she has with past products. “I am going to release it once I am happy with it,” she wrote on X.
