LEGO Game Boy: A Technical Experience Combining 3D Printing and Hands-On Game Modification
LEGO Game Boy: Merging Fun with Technology
LEGO recently released the LEGO 72046 Game Boy set as part of its fall celebrations, representing one of the smallest video game sets the company has launched. However, there was a missing technical aspect in the original set: the ability to play real Nintendo games.
Modifying the Set to Run Original Games
Natalie the Nerd, renowned for modifying Game Boy devices within the tech community, successfully transformed the set to run original Game Paks or any modern homebrew games. She announced that she would offer a modified version for $50 to gaming enthusiasts, allowing them to enjoy arcade games on the LEGO Game Boy.
Technical Challenges of the Project
Before the set was officially available, Natalie took measurements from the press kit to create a custom version. Thanks to her deep expertise with the Game Boy, she found that redirecting the CPU, printed circuit boards (PCBs), power management, and capacitors were not major challenges.
The biggest challenge, however, was fitting all these components into the compact structure of the set in a way that allowed the games to run efficiently. This demonstrates how compact design and technical precision can be combined to deliver a complete gaming experience even on the smallest devices.
Precision Challenges in the Modification
What might seem like an easy task for Natalie is far from simple. The project requires taking precise measurements at the millimeter level, followed by 3D printing custom components. Additionally, Natalie built a custom circuit board to operate the device without resorting to easy solutions like emulation.
Space-Efficient Design
Natalie leveraged the original cartridge slot in the LEGO model to insert real cartridges and run games, serving as a clear example of how compact design can be utilized to achieve functional performance within limited space.
Tuning the Tactile Buttons
Since she received the real set only a few days ago, Natalie faced challenges with the tactile button behavior on the LEGO device. Fortunately, LEGO manufactures precise buttons that perform well for actual functions. Currently, to make the A and B buttons work efficiently, Natalie used a rubber band for temporary stabilization. For a permanent solution, she plans to 3D print a LEGO piece to hold a custom circuit board, enabling the buttons to function perfectly.
Power Circuit and Smart Connections
According to Natalie, the power circuit used is the same as the one in her Safety Charger boards, with a minor modification to include a soft-latching power button. The board also features additional outputs to connect the 3D-printed button matrix and audio outputs, reflecting meticulous attention to organizing functions within a limited space.
Power Connection and Mounting
Electricity is supplied via a USB-C port connected to a 3D-printed adapter, designed with LEGO-like pegs for secure fastening, ensuring component stability within the set’s compact structure.
Remaining Technical Challenges
So far, the speaker function has not been activated, as Natalie is still exploring the best way to connect it to the audio outputs. Meanwhile, the back panel, which holds the dummy cartridge, has been modified to include a slot that activates the game for real, an important achievement that brings the gaming experience closer to reality.
Additional Set Requirements
The additional set that Natalie plans to create for interested modders requires a basic level of soldering skills and understanding of electrical circuits. This reflects the project’s focus on hands-on technical experience rather than ready-made solutions, making it an educational opportunity for beginners serious about device modification.
Availability Expectations
So far, Natalie has not announced a release date for the LEGO Game Boy DIY kit, but it is expected to be available in the coming weeks. This suggests the original set could transform into a practical learning experience for beginners and enthusiasts of precise electronics.
✦ ArchUp Editorial Insight
The LEGO Game Boy modification project can be seen as an opportunity to experiment with technical innovation within a confined space, reflecting the importance of careful design thinking and component organization, a familiar challenge for architects working with tight spaces and interdependent elements. On a positive note, the project demonstrates the designer’s ability to leverage 3D printing and re-engineer components to achieve practical functionality within a small structure, highlighting the significance of combining technical precision with creative design.
However, there are several cautionary points when attempting to translate this experience to broader fields such as architecture. First, the project relies heavily on individual expertise and specialized skills, making it difficult to replicate or scale as a practical example in educational or professional environments. Second, the dependence on highly precise modifications and custom parts may limit the feasibility of applying the concept on a larger scale without significant additional costs or resources. Finally, the end-user experience requires prior knowledge of electronics and circuitry, which restricts the project’s direct applicability to those with a strong technical background.
From an architectural perspective, the project’s concept can serve as a lesson in smart space utilization and component organization to achieve a specific function, whether in miniature models, playrooms, or interactive devices in educational settings. It also emphasizes the importance of integrated thinking between form and function, a fundamental principle in modern architecture, where aesthetic design must harmonize with practical performance.
