I don't know much about FamicomBox but I do want NR. The units themselves seem semi-readily available with all the same games, mostly black box games that seem to be ~$50-100 ea for lower interest stuff. Out of the list of games, Ninja Ryukenden looks like it might even be the last released one, so I won't be surprised if it's super rare. Am I wasting my time trying to casually find this, and if I do, any ballpark on a fair price? I don't think I can even find a picture of one
