Wii U GC Adapter not working well with Netplay

[IDGeek121]

Today, my friend and I had trouble playing together on netplay. With me using the Wii U GC adapter and my friend using another controller (DS3), we found that we kept desyncing, even though we have the same config settings and have disabled memory cards. We have spent about an hour with different controller configurations and two different games.

Everything that we have tried has been on Dolphin 4.0-5222.

Kirby Air Ride
(Config/General) DualCore ON
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread ON
Result: Desync, unresponsive controls for the GC controller (tapped buttons would act like they were held in-game)

(Config/General) DualCore ON
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread OFF
Result: Crash soon after starting game, no indication for why it would've crashed

We turned off DualCore just in case.

(Config/General) DualCore OFF
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread ON
Result: Desync, unresponsive controls for the GC controller (tapped buttons would act like they were held in-game)

(Config/General) DualCore OFF
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread OFF
Result: Crash soon after starting game, no indication for why it would've crashed

This is when we thought it was a controller issue. However, we decided to try another game we had played successfully over netplay.

Bomberman Generation
(Config/General) DualCore OFF
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread ON
Result: Desync. Controls were responsive on my end, unlike with Kirby Air Ride

(Config/General) DualCore OFF
(Controllers/GameCube Adapter) Direct Connect ON/Use Thread OFF
Result: Desync, random crashes.

At this point, I tried using my 360 controller just to make sure that it was not just a problem with netplay.

(Config/General) DualCore OFF
(Controllers/GameCube Adapter) Direct Connect OFF/Use Thread OFF
Unplugged GC controller from the adapter.
Result: Synced. Played perfectly.

It's late here, so we are done troubleshooting for the night, but he's getting his own GC adapter tomorrow. When he gets it, we are gonna see how netplay works with both players using GC adapters. Has anyone else had success with GC adapters on netplay?

I thought when I tested it that buttons were unresponsive because I had two copies of Dolphin running on the same computer. Maybe it is legitimately broken again.

Do you find the analog sticks playing up or is it just the buttons/dpad?  How many GC controllers do you have connected to the GC adapter?

Yeah, the analog sticks were acting wonky as well. I could tap a direction really quickly, and Kirby would stay turning for a few seconds at a time before finally straightening out. While the stick was acting up like this, the game couldn't take any other button inputs either. With the input overlay on, it looked like the controls kinda froze every few seconds, and during this time, the game wouldn't take any new inputs. The issues were only happening while in-game, during City Trial. The controls weren't acting up during the menu. We didn't try any other game modes.

I was using the 1st port on the GC adapter, and I only had the first controller turned on in my controller config. I was also hosting netplay.
