This is cool! You’ve probably seen homemade mods that do something similar to this but this is a professionally manufactured version of a portable game playing device that plays vintage Nintendo Entertainment System cartridges. The Retro Mini features a 2.4″ LCD TFT screen, built in speakers, a headphone out jack and a composite (NTSC) video/audio out cables for playing on a TV. At last, a handheld NES system! It runs on 4 AA batteries and that will give you over 8 hours of playing time. Where was this in 1988?
