Where to place save files for TLoZ Twilight princess on GC?

[Wuuxia]

Been looking forever for a solution, I tried using one with the Memcard Manager (GC) but it never shows up on the file selection screen. Does anyone know or at least try to give me some pointers? Thanks.

Did you check that your game is from the same region as the save file?
