So a few days ago I received a 3DS XL, first thing I checked firmware 6.2, not surprising as it was the black/black and I'm in Montreal, Canada. With a little searching found a store that sells some, found one new 4.2 WOOHOO. So now my question, Gateway 3DS supports 4.1 to 4.5 is there a difference at all between the firmware. Should I update to 4.5 before using the Gateway? Thanks in advance for your answers.
