The title and even the image made this sound like a re-release of the NES hardware (2A03/6502 and all) with a slot to put in actual carts. That would have been a neat way to address limited functioning NES supply. Instead this is just a novelty item like so many other "Plug and Play" arcade packs that have been coming out for the past 10 years. A used Wii costs under $30, but of course people value these things differently. There are emulators that accept SNES and NES carts and plug into a TV, reading the cart data into memory. There are also emulators that try to fully emulate the hardware timings correctly such as puNES and BNES.
