The classic Nintendo handheld has been recreated using Lego pieces and real Game Boy hardware: a developer named Natalie built a Lego model that can run original cartridges and functions as a fully operational console with screen, sound, controls and a rechargeable battery.
How the Lego Game Boy works
Natalie created a kit called Build A Boy that installs working components from a damaged Game Boy Pocket inside a Lego-built housing. The goal was to make the conversion simple and accessible, avoiding soldering when possible and letting the Lego model function exactly like a handheld console.
The preassembled Build A Boy kit includes a custom board equipped with the original Nintendo processor, a 2.7-inch functional display, properly positioned operational buttons, a speaker with volume control, and a rechargeable battery with a USB-C charging port.
Natalie says the fully pre-built version will be “plug and play,” allowing anyone to assemble the console in minutes. The planned price for that ready-to-use unit is US$99 (about R$530).
Options for makers and DIY enthusiasts
In addition to the prebuilt kit, Build A Boy will be offered in alternative formats for users who prefer to reuse parts or build from scratch.
Reuse-your-own-parts version
One option requires the user to supply the chipset and memory from an existing original Game Boy. The kit’s circuit board handles the remaining integration so the salvaged components become operational inside the Lego shell.
Full do-it-yourself version
For experienced builders who are comfortable with soldering, a fully DIY version will be available. Natalie plans to publish the project files for free, encouraging the maker community to modify and improve the design.
Planned accessories and upgrades
Natalie is also considering optional enhancements for future releases. Proposed additions include a glass lens to replace the screen’s plastic cover, video output for playing on a TV, and possible Wi‑Fi transmission, provided it does not degrade performance.
Other Lego Game Boy projects emerging
The Build A Boy concept has already inspired other creators:
- Hairo Satoh from Japan built a Lego Game Boy Color that accepts real cartridges, though his version requires more complex modifications and has no release date yet.
- BrickBoy offers a sustainable alternative that runs an internal emulator and does not use original Nintendo parts.
As kits and creative mods gain traction, fans now have new ways to revive the Game Boy experience—even inside models constructed from Lego pieces.
