is priiloader a homebrew app or homebrew type?That's right again. It needs to be connected to a Wii Remote that is paired to the console. There are some knockoff Classic Controllers that plug into the GC ports, but they won't be able to navigate the Wii Menu. An alternative to all of this if you really want to go that route is Homebrewing and installing Priiloader or something like that, which will allow you to navigate your Wii in simplified menus with any controller you might want to use. I do this when I want to just boot up a game or homebrew without touching my Wii Remote.
Priiloader is accessed, when installed, by holding the Reset button while powering on the console.
