I haven’t needed to update it for a while, so I am probably using a semi-old way to do this. I am still on tiramisu for the hack loader, I am just seeing right now there’s a more recent one (Aroma?) with new features. I don’t know much about that.

My drive is just an external HDD with Wii U’s standard formatting (though I have a Y cable for it, since one Wii u usb port is not enough to power those). It’s literally the same HDD I already used before hacking the console.

I have cleanrip on the virtual Wii to dump Wii and GC discs on a SD, then on PC teconmoon injector to make a virtual console channel from them. Then I install them with Wup Installer GX2 on the Wii U system itself. For GC you need Nintendont on the virtual Wii for controller support etc.

I don’t remember the name for the homebrew that dumps Wii U discs right now, but it’s even more direct since it creates a Wup to install.

Edit : got my wires a bit crossed in here, I do rip and inject my GC games too, but I can’t rip them with the Wii U, that drive can’t read them. I still have an actual Wii with cleanrip to do that. Otherwise it’s the same process.
