I just need some confirmation that I'm doing this right. I got a 3DS with firmware 4.4U, and I have a bit of OCD that makes me want to update to 4.5U using New Super Mario Bros 2, so I just bought the game pre-owned from Gamestop, with 7 days to return it. So if I'm right, do I insert the game, turn on the 3DS, launch the game and run the update that the game offers? (Through sys nand) Should I stay on 4.4 for any benefits, or just update to 4.5? I know they're exactly the same, I couldn't help but to want to get 4.5.
