Jinglefruit said, that there are no way to load the updated version via. hans. I need the preinstalled version of the game :/
Sorry, thats what I meant by retail (I had meant to type Welcome Amiibo's Retail copy, but I must have missed it) if its not preinstalled, it wont work in hans since hans can't load any dlc.
If you use eshop copy already, dumping the new (welcome amiibo) retail copy with braindump and compiling a cia to install will work as long as you delete the old eshop one from your system first.
