Nintendo 3DS gets UI firmware update
Nintendo chose an unusual Saturday window to update the 3DS in addition to introducing New Super Mario Bros. 2. New firmware will let users organize folders as well as more easily slip in game expansions and patches. More features were expected as part of an ongoing Japanese event.
The firmware will appear well ahead of the game itself, arriving in Japan on April 25 where NSMB2 doesn't show until August. Nintendo hasn't said when Americans will get the same upgrade.
