Before your edit, you previously asked about extracting from a GameCube memory card. I don't know if you edited it out because you figured it wasn't possible or because you found out yourself, but for anyone else reading the instructions are in that same Devolution setup guide I linked to:
http://www.wiihacks.com/other-faq-g...ion-guide-usb-loading-gamecube-games-wii.html
Specifically under Part 4: Using An Emulated Memory Card
Yes,I figured it out by actually reading the whole paragraph of your link!

As I understand it,we are absolute obliged to have the Devolution app installed always in our HBC even if we use only a Loader like Cfg/USB Loader and Wiiflow.
In other news,I had forgotten the disc verification issue!Oh my...

I have over 50 GC games,so Devolution for Wii was never a problem for me. But for Wii U , it is currently impossible to enable a disc verification without some ultra weird solution...
