Yes you can play backups on the wii. With HBC installed on your wii you already have a foot in the door. You well need a backup launcher which I recommend Neogamma, various ios(s), and i also recommend Preloader 0.29 to protect yourself from bricking your wii. A little search on the forums should point you in the direction you want to go. If you need help or run into problems reply on this thread and I will help you.
