What's the problem? Describe what went wrong in few words.
In the menus and in-game of these games, when I press my 360 controller's left stick (which is currently mapped to the GameCube's left stick) all the way to the left, the game will interpret it as right. The same happens when pressing down; it will register as up. This only happens in the games themselves; the stick tests in the controller config shows no sign of this happening. When tilting the sticks in these directions the problem does not occur; only when I fully press in the direction does the problem present itself.

What did you expect to happen instead?
I expected the stick to register correctly; that is, for a full press left and down would register as left and down respectively.

What steps will reproduce the problem?

1. Map a 360 controller's left stick to the GameCube controller's left stick
2. Load one of the aforementioned games
3. Use the stick in both the menus and in-games (the in-games tested were Sonic & Knuckles, the Legend of Zelda (NES), and the Legend of Zelda: Ocarina of Time)

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
Version 4.0-2208

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
Yes; most versions from at least three weeks ago work (I cannot remember the exact versions, just that time frame). Dolphin 4.0.2 works as well.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
None that I can think of at the moment.
