If I am correct, all I need to do in order to enable the extra sound channels on the NES is by soldering on a 47K(Preferably 50) which I have already done and solder a wire between the unused expansion pin on the 72 pin side and the extra audio on the 60 pin side. My question is this: Will this adapter (http://shop.retrogate.com/Famicom-To-NE ... -FTNES.htm) work for this? Is there anything missing on the adapter itself? Will this work the same as the NES gyromite converter? Thanks
