Hyperkin is targeting consumers annoyed at Nintendo's decisions about the 60 game NES Mini Classic being discontinued so early. It plays your NES carts, in 720p. Comes with a controller, and has ports for your original ones. I have no idea if its any good, but since its shouting 'all hardware - no emulation' I'm guessing its an NES-on-a-chip design system.
