Second protontricks.
Also, when you open random exes with proton tricks, it will give you a list of existing proton instances. If you have a decent steam library already using proton, it’s going to be a list of installed games. If a game on there uses the dll that you need, you can just pick that game and you don’t need to setup anything, it already is.
I asked Google for a list of games that use directx9c, and it gave me Fallout: New Vegas, The Elder Scrolls IV: Oblivion, Portal (early builds/legacy render paths), Left 4 Dead 2, and Mirror’s Edge. L4d2 is free I think, so you can just install this game then run your game through that proton instance. Zero headache.
This probably has some hidden caveat I’m not aware of, I’m just trying to play games.












Image files can contain thumbnail exif data. Basically the thumbnail isn’t created on the fly every time its needed, it’s a second image in the same image file. Some software doesn’t edit that exif data when it edits the image, so you can end up with a mismatch like this.
Try a different image editor
