Transferring save game files from one Wii to another?

notes (if you don't read the whole thing) : there are some games that you can't copy for certain reasons

• If the game has never been played on the target Wii, you must load the game first (no need to play), return to the home screen then copy the game data file from the SD card to Wii memory. The Wii will now recognize the copied data file.

Games you can't copy normally have an online component or mode, making those savedgames tied to the console.

And this bullet is true. When I got my WiiU last year I didn't do the Wii2WiiU transfer but I manually passed a few saved files... each time I had to launch the Wii title before copying the save file.
