Can i set a custom global save dir?

[Douwe]

I want to set a custom global save directory on the drive on which my dolphin builds are installed so I don't have to move them from build to build or have them on another drive.
I'm using windows 7

Is there anything wrong with the current global directory located in My Documents?

If you really want to set the global user directory location manually, you can do it by editing the registry: https://dolphin-emu.org/docs/guides/controlling-global-user-directory/#Choose_the_Location_of_the_Global_User_Directory

But if you just want to set the location for saves (GameCubed memory cards and the Wii NAND) rather than the location for all Dolphin data, you can do that in Config > Paths.
