You're file doesn't work, dude. I tried. Can you tell me what I'm doing wrong? Or your file need to be updated.
I still use a version of it practically every day, so yes... it still works.
As to what you might be doing wrong, I'm not sure.
The first idea that comes to mind is that you are putting the file in the wrong place. It should go in the game's
/game/
folder.
Beyond that, I wonder what your expectations are. Perhaps you're expecting it to do something it doesn't actually do. It adds a keyboard toggle for auto-forward. Once the file is put in the game's directory, you should be able to press [ALT+PGUP] to toggle whether auto-advance is active or not. You can edit the file to use a different combination of keys... I dunno, if you're perhaps using a laptop where the PageUp key isn't easily used.
The other settings... The sound volumes are only set for the very first time the game is run and the file must be placed in the game's folder before the game is run for the
first time. After that, the volume is left completely alone so the player can change it to whatever they like without this file constantly resetting it for them.
The most obvious sign the file is working correctly though is the way the game's dialogue is displayed. By default, most games show the text immediately. My file changes the default behavior so that text is shown progressively, almost like one character at at time at what is a comfortable reading speed for myself. Again, this is only the "default" behavior and can only be done by copying the file before the game is run for the first time. After that, it will use whatever settings the player was already using.
