Just ahead of the Nintendo 3DS firmware update scheduled to go live this week, Nintendo in Japan have pre-emptively released a warning that the update could cause a freezing bug within Ridge Racer 3D.
The bug occurs on the“Race Select” or “Machine Select” screens, prior to starting a Single play or Grand Prix race, if you press B. This could cause your game to freeze up. If it does, you can hold down the Power button to turn the 3DS off, then restart the game.
Nintendo apologize for the error, and say they will provide a second firmware update in mid-June that fixes the problem. It isn’t clear yet whether this issue is specific to Japan, or if it applies to other regions as well.
Update: The bug affects U.S. systems as well, according to Nintendo of America. Thanks to SJ in the comments for the heads up!
