I have a 3DS XL on firmware 4.4.0-10U. Should I update to 4.5 before using Gateway? I may be misremembering, but I thought I'd read somewhere region-free only works with 4.5 or maybe it's that it doesn't work with 4.1. Can't seem to find that info now. At the very least it would have fixes and may be a little quicker than 4.4.0-10U, right? To that end, I borrowed this: Can I use Luigi's Mansion: Dark Moon [USA] with 100% certainty that the 3DS XL will update to 4.5?
