To enter cheat codes on a Wii, do you need a wireless keyboard?
no unless a game just has cheat codes in it you can look thoses up online and it will show letters on the screen and you can select them with the wiimote otherwise you need to look up the homebrew channel online download it to an sd card and the bannerbomb if you have a certian version of the wii menu and if it says you need to pay for it its a scam and you need to leave that site and go elsewhere once you have both the bannerbomb and the homebrew channel on sd card put in the wii and go to the sd card menu it will ask you something you say yes and the bannerbomb starts it will disable the secruity thing nintendo put in an updated wii menu to stop people from loading the homebrew channel and load the hombrew channel on to your wii from their happy hacking
