I've just purchased a japanese new 3ds ll as a cheap new "main" system (I wanna keep my old one intact and not have to risk losing it), and I would like to be able to install my collection of games on to it (via CIA files). I'm considering region swapping, but I've heard that installing CIAs containing DLC for games call back to the eShop and therefore won't work on a region swapped 3ds. Is this true? And if so does that mean I just shouldn't bother region swapping if I want to still be able to use DLC CIA files?
