I have a buddy who would like to try the USB installation method. He obviously can't use my favorite tool (Wii U USB Helper) because he doesn't have a windows machine. Linux only. I know that jnustool is java based so I guess that will work. For someone that has been lazy and is just used to clicking a game name in Wii U USB helper how would I use jnustool on Linux? I assume I'd have to find a ticket after that correct? Does jnustool download a valid ticket?
