Dolphin 5.0-6339: Wii games crash when using Hybrid or Emulated Wiimote

[DJBarry004]

Hey all. Having some issues here.

After a month or two without updating Dolphin, I decided to give the build 6339 a shot. So far, I´ve found this sole issue: Dolphin will crash when booting a Wii game, if I set the Wiimote to either Emulated or Hybrid. Setting it to Real does not crash the games (and no, I don´t have any physical Wiimotes. I don´t use Hybrid either, only tried it for testing purposes).

When checking the "Logs" window (View tab -> Log), I noticed a certain line colored in red that appears when booting any of the games with the Emulated Wiimote. It reads as it follows:

IOS\USB\Bluetooth\BTEmu.cpp:1465 E[IOS_WIIMOTE]: HCI: CommandDeleteStoredLinkKey... Probably the security for linking has failed. Could be a problem with loading the SCONF.

Any ideas?

For now, this is keeping me from playing Wii games that only use Wiimotes (namely SMG and SMG 2, I always play MKWii and SSBB with emulated GC controller).

Thanks in advance.

Have you tried deleted SCONF?

Will try in a moment, then report back.

EDIT: Deleted SYSCONF in Dolphin Emulator folder, in Documents. Still crashes and shows that same line.

EDIT: I did some digging inside the code, and found this function.

Was there some recent changes to it? This issue never happened to me before.

Also, did some testing with the last build that worked for me (5934). The same error appears, but the games won´t crash during boot.

And what is the actually last version that worked for you? You can find this by bisecting the builds using the bisect tool made by Helios and can be found in this thread: https://forums.dolphin-emu.org/Thread-green-notice-development-thread-dolphin-bisection-tool-for-finding-broken-builds

I just solved the issue. For some reason, having Emulated Wiimote and Emulated GC controller both enabled did not make the games crash. After that, they never crashed again when only using Emulated Wiimotes.

I will do the bisecting nonetheless.

EDIT: The crashes came back. Did the bisecting too. None of the builds between 5934 and 6339 show the latter´s behavior.

Looking at the exact changes made in 6339, only one appears to not be Qt-specific. Since the error still occurs for me when using WX, the one change to WiimoteEmu.cpp is a likely culprit.

This is now fixed in 5.0-6356. Thanks for bisecting it.

[DJBarry004]

Nice to hear man.

EDIT: @JosJuice - are there any issues with the buildbot? It´s still not available for Windows.
