While my BlazBlue was saving, I ejected it, and while the 3DS was restarting to the home screen, I kept slotting the game in then back out, and now the 3DS icon is blank, and the top screen doesn't show anything no matter what I highlight, and when I moved the 3DS icon somewhere else, it froze, but the music's still on. Had to force power off.
Then I froze it again, but this time I can't navigate anymore. Probably cause the timing's different. Just a small glitch, if you want to try it out.
