Tip

Regarding Engine.ini

• To locate the game's Engine.ini, the easiest way is to go to PCGW and look at the Configuration file(s) location section.
  • Example - for Clair Obscur Expedition 33, it's located in %LOCALAPPDATA%\Sandfall\Saved\Config\Windows, create if missing
  • Example - for Witchfire, %LOCALAPPDATA%\Witchfire\Saved\Config\WindowsNoEditor
• If the Engine.ini doesn't exist, you'll have to create it, and possibly make it Read-Only if the game deletes it on boot or doesn't work in general.
