<short_description>Loads games from USB-devices</short_description>
|
||||
<long_description>USB Loader GX is a libwiigui based USB iso loader with a wii-like GUI. You can install games to your HDDs and boot them with shorter loading times.
|
||||
The interactive GUI is completely controllable with WiiMote, Classic Controller or GC Controller.
