About This File
The patchers remove pillarboxing from the game at 21:9, 32:9 and 48:9, resulting in more horizontal FOV.
Some of the in-game images and cutscenes do not appear to be wide enough to fully fill the screen, but the main cutscenes, menu and gameplay become free of black bars.
Unpack the archives using software like PeaZip or 7-Zip and pcgw as the password, then patch \ChildrenOfMorta_Data\Managed\Assembly-CSharp.dll within the game folder.
Tested briefly at 2560x1080 and 5760x1080 in the latest GOG version.
