You would probably have to make it Loadiine ready by yourself with the correct encrypted files. Loadiine is really getting outdated. There is a site that I will refer to as "The Brigand's Cove" with a popular european download that you can use Cdecrypt on after for Loadiine
Download w/ USB helper, then after its finished, right click (should now be in your downloads section in USB helper), then choose pack/unpack. I have never tried it with WiiU because I don't use loadiine anymore, but it worked for me to turn a 3DS dl into CIA.
Yup. I heard someone talk about 15 minute load times. While that might be exaggerating a bit, it really does seem like the game is almost unplayable with Loadiine. Not surprising considering they had to bundle an update on-disc containing a lot of the important files to shorten the load times.
Use USB helper and get the installable one and install it with wup installer then you can also use online features ,for this game is the dlc addon content ,what also can be Installed if you choose to do so what you can't do online stuff with loadiine either.
