I am trying to make a portable games console using the raspberry pi and i've came across a nintendo ds emulator. I'm trying to find a touchscreen for it but I can't find an accurate one. I found this one and I was wondering if i calibrated it with a stylus would it work like a ds?
Yes that will work. You also might want to look at this article http://readwrite.com/2014/10/22/raspberry-pi-compatible-touchscreens
