I used Wii U USB helper to download some gamecube games (following the proper injection process), and installed them on my Wii U. But whenever i boot the game i get a Nintendont menu saying "Failed to create save data". I have both the Nintendon't forwader on my Wii U menu and Nintendon't on the homebrew channel on my vWii (enabling a virtual memory card). What can I do to fix this?
