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.
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.
