If you want to use a 3DS analog stick on your portable, due to size or comfort, this is the diagram for you. I strongly suggest you also take a look at SonyQrio's guide (viewtopic.php?f=36&t=8250). I just thought that the N64 thread deserved its own 3DS analog stick thread. With the help of SonyQrio, I have successfully wired up the 3DS analog stick to the N64! This mod also works for GC. To get to the contacts as shown below, pry up the plastic above the ribbon cable until it cracks. You can use a screw driver to pry it up if you need to. Once you have done this, simply bend it back and forth until you can pull it right off. Next, pull back the ribbon cable until it comes off. You can now successfully solder to the pins! Now, here's the schematic for the stick itself: Thank you Sony for theorizing the putting of a 1K resistor between the X and the Y axis. It eliminates the conflict that caused the inverted axis problem. Once you have wired it up, It should look like this: Hopefully it looks less beta than mine . I'll have a video soon. In the mean time, wire up those 3DS analogs! - mymixed
How hard would this be to do in reverse? As in wire the GC analog stick to replace a 2ds analog stick?
Wire the single +5V terminal to the Gamecube's dual 5V inputs and single GND to the dual GND. X to X and Y to Y, and pray the impedance works with the 3DS hardware.
