Micro Sd With SD adaptor?

Hi there,

Would it work to install hombrew channel,
If i put the files onto a Micro Sd memory card and used the sd adaptor in the wii?

Yes. I did this :).

Anywhere you can use an SD card, a MicroSD adaptor should work just as well. The cards work the same way, the adaptor just extends the connectors to fit in an SD slot.
