Check out this cool mod of a fully fledged NES emulator that has been built into an NES cartridge form factor. It boasts a 2.8″ LCD display as well as original NES controller buttons, crammed into an ancient Super Mario Bros./Duck Hunt combo cartridge. The cartridge connector board at the bottom has been broken off for added convenience. Being an emulator, it also handles Game Boy and Game Boy Color games while handling MP3 playback and FM radio. A video-out port has been retained just in case you’re tired of action on a 2.8″ display.
