Is the Plailect LUMACFW guide the same with a Japanese N3DS Do US carts work through the region unlocker? I would like to use this as my main DS. Is it possibly to transfer all the data from my U.S. 3DS to the Japanese N3DS? Are there any downsides to having a Japanese N3DS with U.S. Firmware? (Assuming I can install U.S. firmware on it) The only reason I'm importing is to have a non XL black N3DS, not to play Japanese games, so if there's a way to install U.S. firmware to essentially turn the handheld into a U.S. region DS I'm willing to do that. If the above is true, could a friendly GBAtemp user guide me in the right direction?
