Probably won't use SanDisk micro SD in 2DS

I’ll wait until I get the New 3DS, and use it in that. Then I don’t have to format it more then once. I’ll know if it’s the New 3DS, if it takes micro SD cards. The old 3DS uses regular SD cards. You should have to take the back plate off too, to get to the micro SD slot. If none of that is the case, I got an old 3DS XL. And I’ll probably send it back to Amazon.
