AlphaYellow1: So for this tutorial, you will need RInput and DxWnd, just search online and you'll be able to find them easily. Here are the steps needed:

1 - Download and extract the latest version of DxWnd and RInput to the game's directory, or wherever works best.

2 - Run DxWnd. Right-click in the middle of DxWnd's window and select "Add".

3 - Name the profile/game, and browse to game's directory and select the SoF.exe. Click "OK".

4 - Right-click the profile that was just created and select "Modify".

5 - Go to the "OpenGL" tab, and tick the "Hook OpenGL" and "Force Hook" boxes.

6 - Go to the "Video" tab and tick the "Custom resolution:" and "Initial resolution:" boxes.

7 - Write the desired resolution in front of the ticked box.

8 - Select the radiobox that matches your aspect ratio.

9 - Click OK to save the profile settings.

10 - Now run the game, and select a low resolution ingame that has the same aspect ratio of your chosen resolution in the game's DxWnd profile.

11 - Turn off "Fullscreen" in the game's settings and save, it will be all messed up but don't worry. Now alt+tab back to Windows and just close the game.

12 - Before running the game again, open RInput.exe and type SoF.exe (it's case sensitive, so the executable name has to match exactly).

13 - Run the game again, and turn "Fullscreen" on again in the video settings.

14 - Go to "Miscellaneous Options" and change both "Mouse X Sensitivity" and "Mouse Y Sensitivity" to 1. You'll increase the sensitivity with your mouse's DPI instead, since the ingame sensitivity makes the mouse move in a stairstepped way, and not smooth.

15 - The menus' cursor will move in a weird way, but during gameplay it's just fine. Enjoy :D

(I'm not sure if this works for multiplayer, better not try the RInput method since it might detect the game code is being changed and might ban you, but I'm not 100% sure)
