Is there a way to boot to the Wii menu in Dolphin? I've used a bunch of different configs and forgotten what saves are on what config. I'd be easy to look at them in the Wii system menu (and I'd imagine that should also allow exporting to an SD card for transfer to a real Wii).
Extract it anywhere into its own folder and run the exe
Hit the Database button
System -> (towards the bottom) System Menu -> v513
Check the Pack WAD box and hit the Start NUS Download!
After it's finished it should be in (the directory you extracted nusd to)\titles\0000000100000002\513
Take the .wad file and place it in the directory Dolphin checks for your games
Open Dolphin, right click the new entry in your games list, hit Install to Wii Menu
Now to load it up go to Tools -> Load Wii System Menu
