Right now, I've got v4.1U on my modified wii and I play games via Homebrew Channel > Configurable USB Loader. I was able to use the latest version of Wii Backup Manager to transfer a 4.08 GB Call of Duty: BlackOps wbfs file to my external USB hard drive successfully. However, the 6.92 GB Super Smash Bros Brawl wbfs file I downloaded will not transfer and gets a disk read/transfer error. Any idea why? I was suggested to upgrade to 4.3U via modmii but are there any suggestions on how to copy SSBB to my external hard drive? I've read articles on burning the file to a dual-layer disk but I have no idea how to do that and I also have no idea where to buy a dual-layer disk. I've also seen save files for the game but I have no idea how to play a save file on to my wii.
