What's the problem? Describe what went wrong in few words.

When trying to use netplay with 2 Emulated Wiimotes each using Nunchuck extension, desync always occurs within the first 30 seconds of loading the game. The desync is sometimes noticed even at the main menu, but can quickly be seen by starting a new game and moving around.

What did you expect to happen instead?

Gameplay to be synchronized for client and host

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Setup two portable Dolphin directories with identical settings (including same Cache and Wii NAND).
2. Enable two Emulated Wiimote controllers each with Nunchuck extension.
3. Host a netplay session from the first Dolphin instance and join the session on the second Dolphin instance.
4. Assign Wiimote 0 to first instance (host) and Wiimote 1 to the second instance (client). Disable all other pads/wiimotes.
5. Start netplay session. If a desync has not be noticed by the main menu, start a new game and move around and swing the lightsaber. The objects in the starting room are destructible and drop currency that is picked up. The currency picked up in one instance will not match the currency picked up in the other instance, and player positions will likely vary between the instances.

When testing, the desync was noticed with 2 instances on the same machine and across a network to another computer.

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?

dolphin-master-4.0-6490-x64, dolphin-master-4.0-6482-x64, dolphin-master-4.0-6270-x64

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

Using dolphin-master-4.0-4784-x64, the desync does not occur (not sure what the latest version that does not desync is, but this version worked correctly).

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