Texture Pack Directory Linux

[Mephisto-DCIX]

I'm trying to use some custom textures, so I have downloaded the textures, and I've ticked "load custom textures". It then instructs me to place the textures in the user/load/textures/<Game_ID> directory.
However, as I am on linux no such directory exists and despite my searches I cannot find where to put the textures. If anyone could help me it would be much appriciated.
Thanks

Your Dolphin user directory is at ~/.dolphin-emu. So the Textures directory is at ~/.dolphin-emu/Load/Textures (do note that your filesystem is most probably case-sensitive).
