If I lets say was using a backup of Smash Bros 3DS. Would it still be able to receive patches like new updates to allow me to have amiibo support and etc? If so could they be natural ones like from the software or would I have to download some file from an outside source? Also if I then paid for DLC yet wanted to use it on the game would that work too? BTW are there ways to get DLC for free like .cia to install or something?
