Emulator

Can you bisect to a more exact build? a 5 year range doesn't really help us much with determining what may have caused the issue. If you cut the range in half and bisect it, it's possible we could find out who change the behavior and how, which will let us assign this to someone.

I will try to find with version after 5.0-11195 breaks it for me

Ah sorry, I missed that. Yeah, that makes the range much smaller. If you can find out what change broke it that'd be great. My DolphinBar no longer has working infrared so I can't verify it.

so far I found a bulid that started breaking dolphinbar - https://dolphin-emu.org/download/dev/d31249593421dcdb4f6ef09485ec7e3e96cb4632/

I just found isssues are fixed as long as option Enable Speaker Data is enabled in controller settings after 5.0-13221

I can confirm enabling Speaker data makes the cursor work smooth again.

Arch Linux, dolphin-emu 5.0.r13772.6c23e163e1-1 package

Also on the newer 1:5.0.r13869.a45a0a2066-1 and dolphin-emu-git 5.0.r13871.gbc4d0b3ef8 packages.
But on those packages Dolphin bar is not working when I run games from the command-line (dolphin-emu -b -e /path/to/iso). Wiimote connects (rumbles and notification at boot) but there goes something wrong when game is loaded with error message "communications with the Wii Remote have been interrupted.".

Strange enough Dolphin Bar and the Wiimote work when I start games from the Dolphin GUI.
Shall I make a ticket for this?
