I have NES pad here I want to hack for my jamma test station. I have a few diagrams I found on the net but my search has turned up empty for direct instructions on the best way to do this. So I figure with some help we can work out the best way here on the forum so everyone can do this.
So to kick it off I have these two diagrams. They do seem to be a little different from each other.
