PowerA Wireless Gamecube controller analog triggers?

[Alderisio23]

Trying to use my PowerA wireless gamecube controller to play Mario Sunshine for GC on Dolphin, but the L and R buttons cant be made into analog triggers (which means for example in the game I cannot spray water while running).

Does anyone have a work around for this? Would like to stick with this wireless GC controller but seems like it isnt an option.

You'll need to configure something for R/L Analog, you will also need to change the threshold/deadzone, but I'm not sure what they should be set to.
