Dolphin cannot create in-game saves

[Asith]

Right at the start of the game, it gives me a pop-up saying "You will be unable to save the game" and lets me continue to play with saving disabled.
On my Wii, this screen usually displays "Checking Wii system memory..." before loading the game correctly. I assume there's just some Dolphin setting that is misconfigured.
I'd prefer to use actual in-game saves rather than savestates. The game itself is called Spectrobes Origins though I doubt that matters

Probably worth starting by checking that Config, GameCube, Slot A is GCI Folder or Memory Card. If that's fine then it is probably some sort of permission issue. Or maybe onedrive.
