Unresponsive/unrecognized controls in Retroarch Wii

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

With this latest version (or versions?) the controls for the Wii are unrecognized by a bunch of cores, controls are unmappable and won't respond during game. I'm not sure if it's just mine, or the issue is with everybody's.

Expected behavior

The cores used to load. And the content loads, and then the controllers respond. Some cores still do, but many of them don't.

Actual behavior

Unresponsive controls, you cannot even map the controls because the buttons for the Wiimote or Nunchuck and possibly even the classic controller won't register. But strangely the retroarch menu still works, and you can still access the menu with the home button, so it's completely baffling!

Steps to reproduce the bug

I have nightly versions from both July and August, and the cores seem to do it on these versions. I've also compiled a couple of cores myself using a virtual machine running Ubuntu and same thing.

Bisect Results

I'm not sure it just happened all of a sudden. I've tried deleting the retroarch cfg files and letting them generate again, and tried replacing the boot.dol file with different versions thinking it could be that.

Version/Commit

You can find this information under Information/System Information

• RetroArch: 1.9.0

Environment information

Wii

Begin by reproducing the issue on Wii with RetroArch 1.9.0 and the nightly versions from July and August, comparing affected cores with cores whose controls still work. Check the generated cfg files and boot.dol while testing Wiimote, Nunchuck, and classic controller input; done means the affected controls can be mapped and respond during gameplay.
