Problem installing backup games to usb loader gx

Hi guys,
i was trying to install my burned backup games to uusb loader GX, but it tells me "not a wii disc", those backup games work perfectly fine on softchip loader..

anyone has any ideas?

thanks for helping

If you HAPPEN to still have the ISO files on your PC, then you can transfer those files via WBFS Manager. As someone who has not worked with burned games in the past, you MIGHT be able to simply make a copy of the disk onto your PC like you would with any other disk. All of this is pure speculation quite frankly, but I don't see why it wouldn't work. >.>
