I tried putting my Wii VC Game in my SD into the install directory using FileZilla, but for whatever reason the transfers kept failing partway through the process. So I decided to put the Wii VC game in a USB into the install directory and it doesn't show up at all. It only lists the ones in my SD. Does the app even support installing from USB? If it can install to a USB, I don't see why it shouldn't install it from a USB.
