The nag screen doesn't instantly update the 3DS. First, the System Settings opens after pressing A, /then/ you probably have to accept terms, and after accepting the terms it finally updates.When I get the prompt asking me if I want to update when I open my 3DS, I'm always afraid I'll hit A, intending to start a game, but that the update prompt will appear before I have a chance to react. If I do click OK by accident when that appears, will it give me any chance to cancel before it's too late?
