I am not sure if anyone else wil find this useful but here goes. Nothing special.
I just got my 3 in 1 Magic Joy Box to use my gamecube controller with Dolphin. After getting all the buttons and d-pad to map, the two sticks just would not work. After a quick google it seems you need to manually map the sticks. To do this right click on the direction you want to map and a new window will appear. To map you want to select the proper direction and then click the Select button and then click OK. See the screenshot below which would map c stick left to Axis Z-
You now need to do this for the other directions of both sticks but figure out what should be mapped to what. To help with this I have done some trial and error and figured it out for you. It's just a case of mapping as I have showed above with the values shown. I also show me independently moving both sticks to show it works.
To make sure this fully worked I tried quick turning in Resident Evil 4 (which is a combination of analog stick and c stick moving in the same direction while beginning to aim with R and it works fine).
