Screen sizes have finally caught up with the size of NES cartridges, enabling the creation of Game Boy XL-like consoles like the Retro Champ. Sporting a 7-inch full-color screen, it has slots for both NES and Famicom carts and built-in controls. Done traveling for the day? A built-in kickstand, HDMI output, and bundled wireless controllers let it connect to a TV for couch-based gaming. It also has a rechargeable battery, and a built-in cleaning kit to keep older cartridges in tip-top shape — no blowing required.
