I just picked up a second 3ds today for cheap and set luma up on it. I am wondering if there is any way to make it so I can use the SD card and games I already have from my other system on this system. I have 4 kids and 4 SD cards so they don't overwrite each others save files and it would be nice if I could set it up so both systems can use all the SD cards. Any help, ideas or just a no can't be done would be greatly appreciated.
