Veering to the right in Super Monkey Ball 2

[CaptainMonochrome]

I use Dolphin a lot to play GameCube and Wii games alike, and one of those games is Super Monkey Ball 2. I played it in versions prior (late 4.0), and I decided to play it again, although the reason why escapes me (maybe because it's fun.) However, whenever I start a stage, if I'm holding straight forwards, I immediately veer off to the right just a tiny bit for no apparent reason. I've tried tinkering around with the settings, even going as far as to disable the x-axis on my controller at one point, but nothing worked. Can anybody help me?

tl;dr For some reason that's not my controller, I veer to the right every time I start a stage in Super Monkey Ball 2, and I need help.

Please show a screenshot of your controller configuration in Dolphin.

The Mayflash Adapters are difficult to calibrate and what you're describing isn't all that odd. Get a screenshot of the controller page while you're holding straight up, and we'll be able to tell for sure.
