A remastered edition is out now:
https://steamproxy.com/steamstore/app/2292260/STAR_WARS_Dark_Forces_Remaster/

This mod comes highly recommended, instead of all the steps below

https://theforceengine.github.io/downloads.html

I will leave the rest of this information below as well, in case it's still needed at some point.

This solution uses GlovePIE to give you vertical mouse aiming, alternate fire with the right mouse button and weapon scrolling on the mouse wheel.

Download GlovePIE[glovepie.org]

Alternate download link[sites.google.com]

Run GlovePIE whenever you play Dark Forces.

Enter the following script:




If you want inverted mouse, switch the first two lines for:


If you do not want the vertical aim to be as sensitive, replace the 1s with a higher number, example:


If you want the weapon scrolling to scroll in the other direction, replace the last two lines with:


"Save As" to save the script. Then you can go to the "Recent" or "Open" menu option to re-load the same script next time you play. Press the "Run" button to run the script. Then load up the game!

Save it as mapper.txt to
C:\Program Files (x86)\Steam\steamapps\common\dark forces\ (or the location of your Steam directory, if not Program Files).

If there is already a mapper.txt file, you may want to back it up. Easy way to back it up - rename the original to mapper.txt.bak

This solution uses the DosBOX key mapping tool. When the game is running, press Ctrl-F1 to open the dosbox key mapper.

These are my suggested changes. This should give you enough information to play around for yourself and make different changes if you desire.

Click on the Backspace button in the keymapper (it looks like a left-pointing arrow, but it's where the backspace key on your keyboard is).
Click on the Del button on the keymapper
Click Add in keymapper
Press Q on your keyboard
Q key now quickswitches and backspace does nothing.



Click on Left-Ctrl in keymapper
Click on Del in keymapper
The control key no longer fires weapon

Click C in keymapper
Click Del in keymapper
Click Add in keymapper
Press Left-Ctrl on your keyboard
Left ctrl now does crouch and C does nothing (it's important to also do the step above, or else you will also shoot whenever you crouch)

Click Numpad 5 in keymapper (it's in the box below the main keyboard)
Click Add in keymapper
Press Backspace on your keyboard
Click Add in keymapper
Press V on your keyboard
You can now re-centre your view vertically by pressing Backspace or V as well as the default numpad 5.

Click F1 in keymapper
Click Add in keymapper
Press P on your keyboard
You can now access the PDA by pressing P as well as the default F1

Click F2 in keymapper
Click Add in keymapper
Press G on your keyboard
You can now access the Infrared Goggles by pressing G as well as the default F2

Click F3 in keymapper
Click Add in keymapper
Press I on your keyboard
Click Add in keymapper
Press C on your keyboard
You can now access the Ice Cleats by pressing I or C as well as the default F3

Click F4 in keymapper
Click Add in keymapper
Press M on your keyboard
You can now access the Gas Mask by pressing M as well as the default F4

Click F5 in keymapper
Click Add in keymapper
Press F on your keyboard
You can now access the Flashlight by pressing F as well as the default F5

Click F8 in keymapper
Click Add in keymapper
Press H on your keyboard
You can now holster your weapon by pressing H as well as the default F8

Save and exit when you are finished.

Note: Pressing the Next button in the keymapper will cycle between the different keys that an event is bound to.

Binding Page Up/Down to mouse up and down will cause issues navigating in Steam/other non-game programs. It also causes the Mission Briefings in-game to scroll up and down when you move your mouse. You can start a mission and then alt-tab to your desktop and start up GlovePIE to minimise problems.

It will be difficult to enter an Agent Name if you have rebound a lot of the keys. For example, with my suggested control scheme Q will make backspaces as well as Qs, Backspace will make 5s and C won't do anything. You may wish to create your agent before you change key bindings, or temporarily unbind them. Although the Agent Name is really just a save game name, so it doesn't matter too much.

This is migrated from part of a thread I made over on the old forums.
