About

Ads-Boy is a custom Game Boy cartridge that captures the VHF radio signals transmitted by aircraft and displays real‑time flight data on the original handheld. By embedding a radio receiver and a small microcontroller onto the cartridge, the device turns the classic console into a portable plane‑tracking system. It also runs a simple game that visualizes the aircraft’s position and heading. The project demonstrates how modern electronics can breathe new life into retro hardware.

The case

Who it is for

Retro gaming hobbyists and hardware hackers who want to repurpose classic consoles for real‑world data capture.

What is broken today

Classic Game Boy cartridges are limited to pre‑installed games and cannot interface with external signals like aircraft radio broadcasts. Enthusiasts lack a way to use the handheld for real‑time plane tracking without resorting to emulation or modern devices.

What it does about it

Ads‑Boy embeds a VHF radio receiver and microcontroller into a cartridge that plugs into the Game Boy. The hardware decodes aircraft transmissions and feeds flight information to the console’s display, while a small program runs a simple visual game of the plane’s position.

Why not the obvious alternative

Unlike generic plane‑tracking apps that require smartphones or PCs, Ads‑Boy runs directly on the original Game Boy hardware, offering a tangible retro experience and demonstrating how to integrate modern radio modules into legacy cartridges.

Questions

How does Ads-Boy receive airplane signals?
It includes a VHF radio receiver tuned to the standard aircraft communication band (108–137 MHz). The receiver’s output is processed by a microcontroller that extracts the flight identification and altitude data, which is then sent to the Game Boy’s display.
Is it legal to use this device?
The radio receiver only listens to public aviation frequencies that are already broadcast; it does not transmit, so it complies with FCC rules for passive receivers.
What hardware is required to build it?
A Game Boy cartridge board, a small VHF module, a microcontroller (e.g., ATmega328), and a few passive components. The project uses standard 8‑pin DIP sockets and a soldering kit.
How do I play the game on my Game Boy?
Insert the cartridge, power on the Game Boy, and the program will automatically start. It displays a simple map and shows the plane’s position, heading, and altitude in real time.
