The way these Mii files work, is that they're all files that are read/seen on the Wii itself. If you open them up in a Hex editor, you can see what they're all like internally.

If you're having trouble extracting, use Winrar to get all the files. You should get an unzipped folder names "Mii Files Untouched", with all the .rsd files inside of them.

However, they still can't be used in the Mii Channel, due to the way the CPU Miis are programmed. They've got two extra bytes attached to the end of their files. By removing these bytes in a Hex editor (I'd personally recommend HxD), you can then read and use them in an online Mii editor, like this tool:

However, things still aren't done quite yet! (I know, there's a lot of parts regarding how this works.) If you notice, all the Miis, when viewed in online Mii editors, have an emptied out ID number pair (with 20-00-00-00 as the Mii ID, and 00-00-00-00 as the console ID). You'll have to replace these with valid Mii IDs (I used ones dumped from the Wii itself) to be able to finally put them back into the Mii Channel.
