I have a Generation Nex too and it's awesome!! I just put in any nintendo game and it turns right on, like a brand new nes from days past. It indeed does play japanese famicom games. I ordered my Nex off ebay for $60 and I also got Mother for $45. It is well worth the investment. There is a slight downside, some games' sounds come out all weird, but it's ok to play awesome old-school games. When you are playing famicom games, the sound comes out almost crystal clear. Oh yeah, I almost forgot! The nes games are really hard to pull out when they are in it.
