Reports from multiple users suggest the 3DS is suffering from a recurring crash issue, across multiple titles.
Super Monkey Ball, Street Fighter IV 3D, Pilotwings, Ghost Recon, Lego Star Wars, and Mii applications have all been mentioned in connection to the error.
Some users have found the issue is resolved by the reset suggested on-screen, while others have reformatted their SD cards to FAT-32 format and eliminated the problem.
Others have had less luck resolving ongoing crashes, and have resorted to returning the console to the retailer for replacement.
We've reached out to Nintendo for official comment and more information.
Thanks, Go Nintendo.
