I know I posted this earlier in the questions answered thread for 2.0 but I just wanted to make sure those who are struggling with this problem see this.
Basically, some people have had a problem with saving in Zelda:ALBW. When the exit to the home meny and press "x" the 3ds hangs for them. This problem can easily be solved if you simply update your emunand. I tested this already but my problem was with Batman:blackgate and Zelda. In both cases they hanged when my emunand was on 4.2 firmware but were perfect when on 6.3 firmware.
I hope this helps!
