So i followed the guide on this video to hack my wii u: I understand each time I wanna play a game I need to load the bootcfw file. And indeed, it works perfectly. I just dont understand whats the difference between this IOSU exploit and mocha? I'm planning on getting Haxchi soon too, so then I wont need to do this, but I need to know what I'm doing first. Also, the Homebrew Launcher channel gives me an error/blackscreen when I try to load it, I dont know what I did wrong.
