We never get tired of playing the classics, and we never get tired of new ways to play those classics -- especially hand-crafted portable ones. A modder by the name of loveablechevy has been working on this custom creation for over two full years now, a combination of a RetroDuo gaming system, providing NES and SNES compatibility, with a PSOne portable screen and a whopping 4,250mAh battery. The resulting creation, shown in a video after the break, looks to be on the beefy side, but we would definitely make room for it in our backpacks.
