One time I booted up the game, waited for it to load, then the title screen comes up. Y'know, just the normal stuff...until suddenly a red box pops up on the title screen telling me that the data for streetpass or whatever could not be found... I had a HUGE panic thinking my game was corrupted! Since when the game is corrupted it will tell you in a red box... I think I'm kinda paranoid about my data corrupting!
