I have looked all over and am unable to find documentation on Wii Backup Fusion. After loading the ISO you can right click and there is an option for "Transfer to image with patching". What is the reason for patching and when is it necessary? I was able to transfer the image without patching to my USB drive and it seemed to play fine, but I am just curious what patching is, what it is for, and when it is required. Thanks.
