I know I might be the millionth person to ask such an "easy" question, but I've been trying and failing for the past two hours to get my Brawl (and other locked save files) off my old Wii so I can use them on my new one. I've read the GAF Wiki, Wiibrew, etc. I've tried Priiloader, Savegame Extractor, Savegame Manager, and StartPatch.
The old Wii is 4.3U and has Homebrew Channel, BootMii, and Homebrew Browser freshly installed. Any help would be full-stop, 100% appreciated.
StartPatch shouldn't be an issue.
Make sure to check all options to allow to copy locked saves, go back to the Wii menu, to the save and even when it appears grayed out; just click Copy; then accept. The only "thing" it doesn't allow is to "move" them.
