This Nintendo Game Boy Might be the World's Smallest, Here's a Hands-On Look

Remember those Classic Console key chains that you can still find at gas stations? Well, one modder turned one into what could possibly be the world’s smallest Nintendo Game Boy, or at least its shell. Inside, there’s an ESP32 processor, 8MB of RAM, 16MB of Flash memory, integrated Wi-Fi, Bluetooth connectivity, and even a built-in speaker.

Best of all, it can run NES, Game Boy Advance, Master System, Game Gear, and more games from some of the earlier consoles. The biggest caveat is trying to play games on its 1.3-inch display, which for short sessions isn’t too bad, especially when you don’t have mobile data available. This was a fully custom build, so you won’t be able to get one online or anywhere else, although you could attempt to recreate something similar using either a Classic Console key chain or 3d printer.
