Gamecube control stick won't work

[iiLoggicZxx]

I'm using the mayflash adapter with my GameCube controller and for some reason the control stick won't work. I'm at the Pikmin home screen and i can press start, the a button and everything else but i can't move up or down. Is this a common error, something to do with Pikmin or is my GameCube controller broken (My GameCube controller has worked before but i haven't used it in around 6 months so that may be the issue).

Edit- Checked with other games as well, control stick either doesn't work or just seats me walking at a specific angle and doesn't stop. The GameCube controller also works fine on the Wii, so is it a dolphin error or something?

I have a Mayflash adapter and I had some similar problems with the control stick always being pushed slightly up and buttons not working quite right. I thought it was the adapter or controllers at first, but I tried moving controllers around and it was only certain ports on the adapter that had the behavior. Blew some air in the ports and the controller plugs and everything worked fine again.
