PicoDMG rebuilds the original Game Boy experience with modern microcontrollers while preserving the original shell, controls, and AA-battery feel. Game files live on microSD, and a game can be selected by holding a cartridge fitted with an NFC tag near the system.

On the original Game Boy, changing games meant inserting a cartridge into the console. PicoDMG modernizes that interaction too: the open-source project by dodger-one can associate an NFC tag in a cartridge or other object with a corresponding ROM and launch it when scanned.

Generative image models usually suggest large GPUs, but this project asks whether one can be squeezed into an RP2350 microcontroller with just 4 MB of flash. It produces 128×128-pixel faces at roughly one image every 20 seconds.

The model and inference code fit into the tiny memory budget, and output can even be displayed directly through a VGA adapter. Instead of scaling AI upward, the project explores how far it can be compressed downward.
