It's me again. What I want is install an USB game loader from external HDD. The problem is that for some reason I can't read any sd cards, I did everthing but keep getting this The device inserted in the sd card slot cannot be used . But I gave up to fix it . So, a sd adapter could do the job. There are some SD card adapter, like gecko SD, PEGA SD. It is an adapter using GC memory slot. Can I use this adapter to install a wii homebrew? maybe there is a SDLoad. I google for it, but didn't find anything. My config is: 4.0U, wiikey ( the first one ), no Homebrew installed.
