I was woundering if i could hook-up multiple USB flashdrives at one time through a USB extention, that makes 1 USB into 4.
Using 4.3U 2006 Wii...
... also, can USB Loader GX load burned DVD-Rs?
I think you can, but have not tried myself. And yeah gx will play backup discs if your Wii's DVD drive is capable.
