I'm just following this guide https://wiiu.guide/ to homebrew and I'm guessing its the "coldboothax" version?
Also, if I need more storage I can just use an external HDD like I would do for the OFW Wii U?
There's already games on my SD card so I want to know what will happen to them after installing CFW? Will my Wii U work as normal just with the new homebrew stuff?
