Wow, what a great idea. Playing older consoles on TVs now is a pain because few TVs have co-ax inputs. There are solutions, but this one is particularly elegant for those of us who have a stash of old NES and SNES cartridges.
The system operates by reading the game cartridge then coding that content through an emulator. That does not really matter inasmuch as the hardware is not original either, but there is something philosophically interesting about the step-removal between the original cartridge and the emulation produced: it is not like playing the original game because one is not playing the original game. This is no more authentic than using any other emulator, despite using original cartridges. Still, copyright holders and cartridge hoarders rejoice: the ghost of Christmas past has arrived!
