Can't get Wii Sports Resort to work from your USB drive? Just follow the video to select an alternate DOL file. You'll have to painstakingly watch the motion plus video (i already did). Then change back to default DOL.
Disclaimer: This should NOT cause any issues with your Wii or ability to play games. If you follow this video all the way through you should be able to play your backed up copy of Wii Sports Resort. I am in no way responsible for any damage you may cause to your Wii or yourself.
