I already got a some advice on this, but I still wanna double check. I just got my refurbished 3DS XL, and it has 8.1 system version. I wanna use Gateway sometime in the future, so it's imperative I don't update to the latest version. I have a retail cart of Pokemon Omega Ruby that I would like to use online for battling/trading. Can I do this safely without triggering an update? I have already switched on Parental control (but no actual restrictions), and haven't even accepted the TOS that keeps showing up. Also, how to game updates and DLC work? AFAIK they need the eShop to download. Does that mean that updates are not possible?
