RetroPie Nes Cartridge
I made this RetroPie gaming rig using a Raspberry Pi inside a NES Cartridge. Its running a Raspberry Pi Zero with RetroPie installed. Currently the emulators are NES, SNES, Sega, Sega Megadrive. It has a 8gb SD Card which allows plenty of games to be played. The HDMI and Micro USB outputs allow the case to taken anywhere and plugged into any TV aka plug & play ready!
