I'm considering buying an N3DS from Japan because the not-xl special editions in the US are expensive and I can get a japanese one easily for $170. I really don't want to get another XL, my O3DS XL frustrates me because of how big it is. I know you can do region changing with secureinfo_a but the eshop won't work, right? I've heard about secureinfo_c but I don't really understand the complexities of the whole process. Can someone clarify?
