@Sparg0ssb It means your SD card is dead or is starting to die. I suggest you backup all of the files you have on it and copy them to a new SD card as soon as you can.
@ThassGamer For someone like me that doesn’t know anyone, I like the zen mode bc I can play the same vs anyone regardless of my opponent’s rating. And I won’t get nervous if I end up fighting like a top player or something.
