What's the problem? Describe what went wrong.
It's a soccer game and it happens when one player using dolphin plays against another one using a regular Wii. Randoms loading happens, but that's not the main problem. The main one is that action seems to "rollback" very frequently, for example, when you tackle an opponent and take the ball, the game "rollbacks" and your opponent gets the ball back. When the ball is entering the goal, the game rollbacks, and the ball gets back in the goalkeeper's hand. Pretty random issues, but it makes playing between Wii and Dolphin borderline impossible :
The issue never happens with Dolphin-Dolphin and Wii-Wii
What steps will reproduce the problem?
Wiimmfi Patch the game, launch it on Wii and on Dolphin, go online and start a match between the two players, try to tackle, do special moves to score.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Yes 12716 is the one I tested it on
Is the issue present in the latest stable version?
Yes - 5.0
If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer
What are your PC specifications? (CPU, GPU, Operating System, more)
i3-6100, gtx 1050, 8GB Ram, Windows 10
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Here's a video I recorded showcasing most of these bugs (I can send the full match too if you want):
Or here's a video from another match, at the following timestamp you can see :
- 3:03 : tackle rollback (alongside players T-posing)
- 3:08 : shot cancelling itself
- 3:40 : same thing
- 4:20 : tackle
- 11:11 : goalkeeper getting the ball back
This sounds like CPU emulation inaccuracies. Something you could try to do is enabling the debug GUI in Dolphin in interface and try running the game, pausing, and disabling parts of the JIT to see if any of that affects it. I'd suggest using interpreter, but in a case like this I think it'd require you to be running full speed, so this is the best we can do.
Alright, sorry for the late response.
Unfortunately, changing the Emulated CPU Clock did not fix the problem (and under 33%, the game's framerate decreases, which is normal).
I tried pausing and disabling part of the JIT with the debug GUI, but it caused a loss of connection everytime, so I couldn't do that.
The FPRF didn't affect the problem either.
What you're going to have to do is try disabling parts of the JIT in the debug before the game connects and see if maybe one of those fix it while maintaining full speed. If not, does the game support recording replays or something like that? If the physics are desyncing, it may manifest in replays.

I tried to record while enabling and disabling afterwards, by comparing side by side you can see that they're the same picture, I don't think there's a difference outside of online play.
And I don't know how to build Dolphin unfortunately, but I could try, from what I see I have to download Visual Studio.
