I am very new to wii modding and I installed homebrew channel and browser. After that i unknowingly updated to the bad 4.3u menu. Now I cant use the bannerbomb exploit to install bootmii. I am trying to prepare my wii to play iso's from my usbdrive. I know about the smash bros exploit but want to be sure i have everything ready to install when i rent it. What must i install when i rent that game to play the iso games?
