I'm trying to hook up an external control for the analog input on the 3ds. I bought a few extra circle pads and was going to just carefully modify the ribbon cable to be used in my project, but I figured someone might know which test points on the 3ds / 2ds correlate to the ground / x / y / vcc points of the circle pad? That would be way easier. I assume they would be numbered the same for 3ds and 2ds, as the digital inputs (abxy, dpad, LR) are numbered the same on both systems. If not, does anyone happen to know which lines on the ribbon cable correspond to what on the circle pad part itself?
