This super small Nintendo Game Boy emulator is the keychain accessory we all would have killed for as kids. Called the Keymu and created by Vincent Buso, this cute little console has four buttons and runs on an Intel Edison chip.
It is basically a clamshell design of the Game Boy Advance SP, just in a keychain size. The Edison chip is a hefty bang for your tiny computing buck, a dual-core 500Mhz processor, 1 GB RAM, 4GM of flash storage, Bluetooth, Wi-Fi, a power management unit and your pick of input/output interface including USB or SD cards.
In the video, Buso plays a variety of NES, SNES, GBA and Game Boy games on the tiny device. On the small 1.5-inch OLED display the Mario Kart Super Circuit looks surprisingly great. But if you are looking to buy one and have this gaming console travel with you everywhere, you are going to have to build your own. Buso has open sourced all the instructions you may need for building your own Keymu!
