I'm pretty new to the Wii U cfw/hacking scene and I've been doing some research. I've hit some confusion about the modern way of installing Wii U backups to an external HDD without using an SD card and have been getting conflicting info. What's the best accepted way to go about this? i.e. not using an SD as a middleman to transfer the files? And is it preferable to use loadiine or directly install the titles to the home screen? Thanks
