I don't have a GameCube controller but I know where I can borrow one. More to the point, my question is: Well, I've heard that you need to take apart your GameCube controller in order to use SaveMiiFrii. Can you put it back together again afterwards?
I used a DDR mat to start the SaveMiiFrii method, a Konami one. Didn't have to modify it. Hope that helps.
Nice, I didn't even think of DDR mat. Lulz, I can be stupid sometimes.
So, it should be possible to reassemble the GC controller in case I can't find a DDR mat?

If you don't have a triwing screwdriver to take it apart, you can mod a flat head to make it work (or use a pen, but that is a ton harder). You need to remove a certain part of the gamecube d-pad if you want to keep the savemiifrii mod forever. Otherwise, just take it apart, and put it back together.
