I heard about this a long while back and decided to open the cart today. Lo and behold there is a black adapter type deal that has connects two boards together. This will work for playing Famicom games on the US system? Does anything on the adapter need to be modified to accept the famicom carts such as breaking off the two plastic tabs on the sides of the converter that connected it the the cartridge housing? I don't have any famicom carts to test and was just wondering who else has done this..
