Overview

• Sydney-based modder Natalie the Nerd demonstrated the Lego set booting real Game Boy cartridges using original chips rather than emulation.
• Her custom board uses an MGB (Game Boy Pocket) CPU with on-package RAM, allowing a PCB smaller than a cartridge to fit the enclosure.
• The prototype powers via USB-C and employs a tiny backlit display after removing a few bricks to make space.
• Controls are operational but not finalized, with buttons wired pending a dedicated PCB mounted to 3D-printed Lego-compatible parts.
• She plans to release the design or a mod kit once refined, as outlets note Lego intended the retail set as a non-playable display model.
