Hi guys need a little help, not sure if this is normal to happened or not, tried googling for an answer but didn't find one, so i decided to ask here. Ok so i get all the things done as it says in the manual for 3ds Gatwey etc. I play the game on the 3ds all is fine etc. When i would like to access my sd card on the pc afterwords to delete the game and add some other one or whatever, every time i insert the sd card into the pc i always get the message that i need to format the SD card so i can use it, i tried on few pc's, same thing. If i put it back into the gateway and the 3ds, all good, can play the game as i have before, so why the SD card isn't anymore readable by the pc once iit has been accessed and used by gateway, do i have to format it all the time once i used it with gateway card? Thanks guys, i appreciate your help.
