Hi I am having a similar question as I am looking to buy a japanese 2DS XL. So to confirm, the region changing process does or does not affect the NNID? If it does affect it, is there a way to prevent that? An alternate method or something? Also if i want to make a new nintendo network if after...
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
