Ok, I know that the DS touch screen is basically a compound 2D potentiometer, so it should, in theory at least, work as an analog stick for any console.
Now, I haven't opened my DS in a while as I destroyed it during an earlier mod (I was bad at soldering back then and I destroyed the soft button pads. I also used wire too thick and it stressed the casing apart), so some information would be nice.
The cable that leads from the touch screen to the mother board, how many connections does it have? I'm guessing it either has three or five.
Also, if the voltage returned to the controller is off by a certain amount, what can I do to fix that? I know there's a component (a magnet with a bunch of wire wrapped around it) that will increase voltage, but I forget what it's called. Would that work to fix the voltage offset?
