What's the problem? Describe what went wrong.

The controls are pretty messed up. I compare the Gamecube Version with the Dolphin:

Gamecube: if you push the stick in a 90° angle left or right, Mario is running a very large circle except if you are running around a small object like a tree, then the circle is very small.
Dolphin: Mario is running in a small circle every time, it doesn't matter if you run around an object or not.

I tried this with a XBOX 360 Wireless gamepad, a XBOX One Wireless Gamepad and finally an original Gamecube gamepad. All the same. It has nothing to do with the deadzone or any other setting you can set either.

What steps will reproduce the problem?

Nothing special is needed to reproduce this issue, not even a special gamepad is needed. Just start the game and move around.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

I tried many versions up to 4.0-9262, but all the same. The first mention i found for this was on May 2014 in this thread: https://forums.dolphin-emu.org/Thread-mario-sunshine-xbox-360-controller-problem?pid=404140#pid404140

What are your PC specifications? (CPU, GPU, Operating System, more)

CPU: Intel Core i5 6600k @4500 MHz
GPU: nVidia GeForce GTX 770
OS: Tested with Windows 8.1 and Windows 10
Mainboard: Gigabyte GA-Z170X-Gaming 7
RAM: 16 GB G.Skill Trident Z 3200 MHz

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I made a comparison video for you, since this is hard to explain. In this video the joystick was pushed in 90° angle to the right on both, Gamecube and Dolphin.
