That's not a Nintendont problem. That's a Wiiflow problem. Run it from the HBC.
I've tried. It won't load, gives the message "This is not a valid Wii application." I've also tried using USB Loader GX, but no games (Wii or GC) are showing up there. In Wiiflow everything except GC games works fine, which is why I mentioned it in that context.
