Hi all,
I have an interesting problem which so far I have been unable to solve, and I'd like to consult your expertise on this. I've looked through the winehq docs extensively and even tried to look at the source code of wine but couldn't figure it out.
Here's the problem: MotherVR - https://github.com/Nibre/MotherVR/releases - is a replacement dxgi.dll for Alien: Isolation on Windows that intercepts DirectX calls in order to show the game in Virtual Reality using SteamVR/openvr. It acts this way by being put into the executable directory and by itself it calls the functions in the original DirectX dxgi.dll.
How could I reproduce this injection in wine? I know dxvk is not supported and it not part of the wine project, but in any case regard this as a broader theoretical question. In that case, I would need MotherVR's dxgi.dll to be loaded first, then internally call the functions in dxvk's dxgi.dll for it to work, right? I've tried many combinations with WINEDLLOVERRIDES to no avail, hasn't worked so far. Would I have to change the source code of wine, dxvk, or MotherVR? MotherVR is still not open-source although it is planned to be.
Also, I wonder if this DLL injection would have memory alignment issues, requiring patches like "Map Image Top Down" - https://github.com/hdmap/wine-hackery/blob/master/f4se/mapimagetopdown.patch -- to work? (this patch is required for the Skyrim Script Extender DLL to work on Linux)
Please advise!
