Inaccurate directions on GCN Controller.

[TailsGuy]

I can't do a straight line on this controller for some reason.
It's official, and I'm using a mayflash adapter on Wii U/Switch mode.
When I Z target in Zelda, I don't go directly backwards, I just shuffle to the left and back a little.
Here's some pictures from a controller test.

These are down, up, left then right.

I have the exact same issue as TailsGuy. GCN controller is plugged into port 1, I have been able to remap the buttons as I would like by editing the config file.

Regardless of the adjustments I make to stick sensitivity, deadzone, etc, the controller naturally rests in a down-left position at neutral which should not be happening. Something seems wrong with the neutral position using this plugin.

I have tested many other games and know that my controller does not have a drift issue. Would be awesome if this was fixed as everything else about this plugin is great.
