Arcade consoles are great nostalgic fun, but their immense size makes it unrealistic for most people to personally own one -- unless the tech wizards at Adafruit get involved. Using a Raspberry Pi Zero computer and some technological know-how, Phillip Burgess built the world's smallest Multiple Arcade Machine Emulator, or MAME.
The tiny MAME from Adafruit is fully playable and hosts classic games like Pac-Man and Donkey Kong. Though its screen is just 0.96 inches from corner to corner, it is a high-definition RGB OLED display that can play arcade games in their original colors. Not to sacrifice the glorious 8-bit sound that accompanied classic arcade games, the miniature machine somehow manages to squeeze in an audio amplifier as well.
Though the machine is not for sale on the Adafruit site, the company gives a moderate overview of how to build it for oneself.
