Gecko 1.9.3.1 no sd codes found error.

[thunder999]

I run the latest version of gecko from homebrew browser and the most up to date homebrew channel and put the .gct file in sd:/codes and named the game ID, but when I run gecko it says no sd codes found,
How can this be fixed?

What game?

How did you make your GCT file?

Did you enable SD cheats in Gecko OS?
