My Brother's game card (Black 2) is not working in my nintendo 3ds. It used to be when I put it in and selected it the screen would say
"Could not access save data. Please turn off power and try again"
Now when I put it in the icon doesn't even show up.
All of my other game cards work perfectly fine.
Has anyone had this problem before and if so were you able to fix it?
p.s. I wasn't sure where to ask this. You can comment if I should ask this somewhere else and I will fix that.
