RED4Ext doesn't work on Steam Deck without adding a Launch Option

[s3r1al]

Improvement

winmm.dll is needed for red4ext, however it's not found after installing the mod. it would be great if you could add this to the games wine config automatically.

This feels mostly out of scope for a the mod manager, except in cases where the mod manager is directly running the game itself (which it currently defers to steam on linux).

I think the most that should be done here is try and detect if the game is configured correctly, but that seems difficult since wine dll overrides can be configured either via the WINEDLLOVERRIDES env var (in steam's launch arguments) or persistently via winecfg.

Such a detection would therefore be rather complex, especially for something that isn't directly the responsibility of the mod manager...

In addition to the dll overrides, winetricks (or protontricks) should also be used to install the d3dcompiler_47 and vcrun2022 libs. I'm not sure there's a same way to detect that they are installed in the wineprefix either...

Perhaps the best course of action here is just to link to the cyberpunk wiki (or similar documentation that could be maintained by the nexus team if preferred).
Such a link could be included in a "tip" popup that is displayed when users first manage cyberpunk, or perhaps when they first apply a mod loadout for which the docs are relevant?
