Hello.
Now I see a little clearer (after tinkering around with Guitar Hero DLC´s)
This WAD File(s) are "Packages" like a .zip/.rar File.
It contains ALL of the
downloads.
YOU CAN NOT install THIS WAD File on your Wii´s REAL NAND.
CustomizeMii and
WADer (Tools for creating/extracting a WAD file) can not handle it because it is no Channel WAD.
WADMii extracted all Files:
but I can not repack a single file (Error: At least one file is missing,the WAD cannot be packed.)
Maybe you can try to use it on an
emuNAND.For that my "wisdom" is very limited,I do not use it for myself,sorry my friend.
--------------------- MERGED ---------------------------
Maybe this helps you:
Banner (and I think Sound and Icon too..) - 00000000.app
The Loader - 00000001.app
DOL File - 00000002.app
I have "tinkered" around with the "
Wii.cs-Tools" but there is so much more I have to learn about this great Tools.Maybe you can do it better.

Good Luck.
