Plus I cloned my Wii's NAND so I have all of the Virtual Console games and savegames, and I also dumped all of my GameCube memory cards and put everything to the Dolphin memory cards images.
Everything is cool and future-proof now!Highly recommend doing this if you have a working Wii - just install Homebrew Channel and CleanRip.
Jailbreaking the Wii U is a little bit more involved as it requires some "special" equipment. It's in quotes as not many are going to have a USB A to ethernet adapter, nor a compatible model, but they aren't all that rare either. But once it's done you don't have to worry about jailbreaking it again. Dumping Wii U games isn't much harder than GC/Wii either.
No adapter is necessary, I set mine up recently.
Some WiiU NAND chips have been prematurely failing, so I recommend adding isfshax when done with the Aroma setup; it makes it easier to unbrick a console with bad NAND.
