DaftMike has created a miniaturised version of the classic NES (Nintendo Entertainment System) and used a Raspberry Pi to play retro games. At 40% of the original size, this is a lovely small build accomplished using a 3D printer. He has used an NFC reader to read mini cartridges which tell the Pi which game to play via an Arduino which actually reads the built-in tags. He added functional buttons and also adapted a gaming controller to communicate with the system. It really is a lovely build and you can read more about it here, on Mike’s blog.
