How do I uninstall the mail patch?

It’s like this now, and I don’t have an uninstallation tool. What should I do?

Hi there!

First, I’d like to know why you’re removing the patch. If you’re trying to resolve an issue, this is unlikely to fix it.

Otherwise, can you let me know if you’re on a Wii, Wii U or Dolphin, so I can tailor the instructions.
