Yesterday I played with my 3DS, and I found by accident something that probably no one had mentioned. Probably most of you know that when you press the right button combination on DSi or DSiXL , you can get touchscreen setup on startup. OK. What about 3DS? Press and hold L + R + (dpad) UP + A and press Power once.This combination will get you straight to the update screen. Don't worry, you can cancel it Another interesting thing is that I set 3D function restricted by parental control. No other options are restricted. While update-startup screen system asked me for the PIN. Dou you know other hidden features?
