I have a sandisk 64 gb micro sd formatted to exfat. Once I have loaded past 5 games, the games show up as white blanks and when I click them nothing gets loaded. Does anyone know why? I have tried loading games with the built in card reader on my laptop and a usb sd card adaptor, but get the same results. I have loaded the games 1 by one, or all at the same time, but they still show up as white blanks. All the games work, it is just a matter of which ever game is past the 5 game limit allowed to show is a white blank. Thank you.
