I have 10.3 Reinand on my New 3DS XL. I have access to my eshop, and this is my question. Can I just grab any cia that has online multiplayer and start playing online right away or do I have to grab the cia and patch it?. Are there probabilities of nintendo banning me? I know it happened to flashcart users, but what about custom firmwares?. is it safe to update a game cart with cias and install dlc cias for it?.
