Hi,
I just registered because of this issue.
I updated to the latest version of dolphin and my gamepad didn't work ingame anymore.
It worked in the gc-pad config menu, and everything was configured correctly, but it didn't work in the games anymore.
So I unzipped the latest version to another folder and reconfigured the gamepad completely, and now it works again.
I thought you might want to know that.
This problem occures if you just unzip the latest version into the folder with an older version.
I don't know if this occured with every version and is commonly known, though XD.
EDIT:
Also because of this problem I accidently deleted my memory card files ... luckily they still were in the recycle bin XD.
