Ok, I know someone has already made these, but I absolutely loved my NES and would absolutely love to mod the one controller I have left. I will post pics when it's finished. All input is appreciated of course. Just a couple questions.... What should I make it? 3.7v, 5v reg, 6v, or variable voltage. Should I make it a regular 510 connection or a bottom feeder (I do not think I can fit a squeeze bottle inside to make a practical bottom feeder though)? What would you like to see?
