What should I do if I’m using the standard Dolphin NAND and can’t verify my account?

I tried to verify my account using the WiiLink Account Linker but got an error because I’m using the standard Dolphin NAND; it’s asking me to use the NAND from my actual Wii, but I don’t have one.

You need a real NAND, you can’t link to a WiiLink account without one.
