Hello,
I did all of this, per your instructions, and ran into an issue when it asked me about a memory card (on my Wii). For some reason, when I tried this earlier today, I didn't realize that I had to use the classic pro controller that was plugged into the wii remote in order to select format, etc.
So tonight I launched it, without the disk, formatted my "virtual"? memory card, and started to play the game.
My question to you is, all of this data is on a 2gb SD card. On that card I have the homebrew install, devolution app, the ISO of Smash Melee, and now I suppose the game save. Will I simply be able to use this card on the WII U, or will I have to repeat the process there as well, losing any progress I have made in the game?
