Game Boy LCD sniffing
A guide and toolset for extracting screenshots from an original Game Boy by sniffing its LCD data bus with a logic analyzer.
What is Game Boy LCD sniffing?
Game Boy LCD Sniffing is a hardware hacking project that enables capturing screenshots directly from an original Game Boy by intercepting and decoding the LCD data bus signals. It provides a guide for physically connecting a logic analyzer to the Game Boy's internal connector and includes a C program to convert the captured digital data into grayscale images. This approach bypasses emulation and offers a low-level method for extracting visual output from the classic handheld console.
Hardware enthusiasts, retro gaming hobbyists, and embedded systems developers interested in reverse engineering or preserving Game Boy gameplay through direct hardware interaction.
It offers a unique, hands-on alternative to software-based screenshot tools by demonstrating how to extract raw video data at the hardware level, providing educational insights into the Game Boy's display system and signal timing.
