I have Wii 4.1u. I use the old method of installing wads (bannerbomb + wad installer + wad folder). I don't have homebrew channel installed. When installing wads I get "ret = -2011" error. When I move some of my old wads (non-bought, installed back in firmware 3.x) to my SD card and play it from there, I get a this cannot be played error. How can I install and play my wads on Wii 4.1u? What cIOS do I need to install (if I need to install any)? I heard something about installing custom Trucha Signers or something similar.
