Did a bit of digging.
Looks like IntifaceCLI.exe is packaged with the game.
Intiface can read configuration files. How is this done in game? What is the command-line?
I've seen people use an IntifaceCLI.bat to add configuration that is easy for users to change, if "IntifaceCLI.exe" is replaced with "IntifaceCLI.bat" (which just runs IntifaceCLI.exe) that might work.
