If the answer is Yes then how much size vWii support (32 GB, 16 Gb or smaller) ?
And why we need a SD card when we can use a USB instead ?
He probably meant a thumb drive, if that's the case then the answer is yes(it works on a normal Wii so it should work on the vWii too). A 32gb thumb drive should work fine.well im not quite sure what your mean exactly.... re-reading your question.... can i use a USB instead of a HDD.......??? the usb part is what you connect your hdd to the wii/wii u with.
