That's the same one I'm using in my N3DSXL. It is indeed perfect. HOWEVER, in order to use a microSD that is larger than 32GB you'll need to format to the FAT32 file system in your PC or Mac.
Yup, it's gonna be easy.
I have never had my finger near the power button either.I'm curious how you folks who hit the power button are holding the system. I have two methods of holding it, and neither have my finger near the power button.
Your NNID can only be on one 3DS console at a time, so you'll have to create a new one.
He could also just call Nintendo (or distributor of his country) to get his Nintendo ID moved.Thanks! I was afraid that was gonna be the case, but so be it
