Codes for VC Games don't work

[MichiS97]

Hey, I'd like to use some gecko codes on my PAL VC version of Majora's Mask. I did everything exactly the same way as with Wii and Gamecube games.
The codes I used can be found here right in the first post: http://wiird.l0nk.org/forum/index.php/topic,3344.0.html
I tried every single hook type in Gecko OS and it always says "SD Codes found..Applying" but the codes just won't work. Can you help me with this?

Try uninstalling and reinstalling the VC game a few times.
