I bought two controllers recently, and they both work great individually, but there is some sort of problem with Dolphin version 5.0-4703 not recognising the analog stick of the second controller. Specifically the emulated analog stick, it doesn't matter which buttons I bind to the analog controls, or which controller's input is used for player 2. Or player 4, for that matter.
However, when I reverted to an old version of Dolphin (version 5.0-1828), the problem was not there. This means my controller issue was not a pressing matter, but it is a problem that is probably worth bringing up with support. I'm not sure if the developers are aware of this issue, or, for that matter, if they already fixed it, but I felt it would be prudent to bring this problem up in case nobody knew about it.
The controllers I was using were both Sabrent 12-button USB Controllers.
