Ok. Just to clarify this up, these are NOT legit, not by any means. They are Japanese Nintendo Famicom clone systems, with the rom images built in. There are hundreds of variations of this exact same thing, and they're ALL pirate. Not a single one of these games is licensed.
ALSO, yeah, the pix they show there look nothing like the actual games you'll be playing on your TV. They're almost all 1st gen NES games that nobody really liked. There are a few prize items on there, and some of these go the extra mile by putting a cartridge slot for playing your own carts, but overall, it's mostly a lot of old games.
And like this other guy said, this one's overpriced. I would expect to pay less than $30 for something like this. Check your local swap meet, or Ebay. I always see them there. Search using "Famicom" or "Famicom Clone" for best results.
