Works fine with my Kingston 8GB HC 4, but can´t get it onto my 64GB SanDisk Extreme PLUS XC I. Both cards are in exFat format, so that can´t be the reason. Can anyone please explain why?, or is there another way to transfer? Also, does this game save directly to the rom?, because I can pick up the game from the last point when switching between systems. (Using Gateway. I thought games were saved on the normal SD card.) Thanks to any who might be able help.
