While every Nintendo 3DS owners are easily anticipating for the firmware that adds the 3DS Shop, the DSi gets the head start by receiving a new firmware.
The new DSi 1.4.2 firmware is now available via download on your Nintendo DSi. No word as to what new features are added in this firmware but a lot of people said that it mostly blocked flashcarts from working and it may prepare the handheld for the DSi game transfer soon.
I guess we can wait for Nintendo’s official announcement as to what the new firmware really adds to the handheld.
