http://lofi-gaming.org.uk/blog/2013...-upgrade-your-3ds-sd-card-to-64gb-and-beyond/I bought a 64gb micro sd card upgrade for my 3ds and it's formatted but when I copy and paste from my old one to the new one, I get the blue light and nothing comes on screen. Also I have no emunand. I have everything copied over to the new one.
