Compatibility Report

This can be fixed by setting the os compatibility to Windows 7, which can be done by running the following command.

protontricks 3681810 win7

to add on Renari comment, you can instead install install wmp11 with
protontricks 3681810 wmp11
apparently for other quartz was needed instead

But now game don't run at all
and will crash after a dozen minutes on last proton-ge following the 14th october patch adding ACE

The crashing appears to be an issue with Proton, the exact same code to add the proper sys calls for ACE support work in wine, but are causing crashes in proton. It is being looked into.

blue protocol is working fine for me on Proton-GE10-21. GE pushed a fix.

As for what Proton upstream needs for the game to work (already included in latest GE from EM imports, hence why the game works):

• Backport of this coremessaging MR from upstream, else the game complains about DllGetActivationFactory missing
• This Wine merge request to fix the game crashing due to Wine unwinding on access violation
• Needs Windows version override to win7 for videos to play, likely due to issues with their Unity video player (see https://github.com/Open-Wine-Components/umu-protonfixes/pull/406)
• Backport of ntdll-Syscall_emulation from wine-staging 10.5 like this one, to also trap syscalls in the top-down reserved area.

Since Proton has its own workaround for the latter (see https://github.com/ValveSoftware/wine/commit/c1f2b81a98ed4116e7ab7bbc9fe8aa26c70549c9), I tested the following and it works too:

Thanks a lot for the info! This should hopefully work with Proton Experimental bleeding-edge branch now (https://github.com/ValveSoftware/Proton/wiki/Proton-Versions#proton-bleeding-edge), yet besides the pre-existing video issue so far. As my initial checks went, the coremessaging part wasn't needed so far (so it wasn't pulled) and I made a different patch instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/9218 .

In "Proton Hotfix" this issue seems to be fixed.
