I bought a 3ds running Luma 9.1 on 11.6 firmware, I've been wanting to play pokemon ultra moon online since I have an actual cart for it and I was wondering if it is safe to update to 11.9 so I can download the update files to be able to use it online. I also have Animal Crossing on there but in .cia form and was also wondering if that would still work/ perhaps be able to go online with it also.
