I am reading the only microsd hc will work and not microsd xc - does this mean that 32gb is really the largest we can go (am thinking to use with gateway 3ds) or should a 64gb microsd xc work ok formatted to fat like on the old 3ds xl with the bigger SD card? Have my n3dsxl (aus) and gateway - but not ordered the microsd yet as I don't want to get one that isn't compatible. Thanks bob
