In the past when considering getting a New 3DS XL I read that it could break the eshop and other features. What I've read lately sounds like the newer custom firmware breaks nothing and can unlock region blocking on any device. I live in the US but would ideally like to get a japan New 3DS XL as I like their color options more. IS there any reason I shouldn't do this? I want to play 3DS/ and GBA roms but also want to play all the DS/3DS carts I own. I'm just looking for some final general advice on this before I make a purchase.
