Aspect ratios besides 4:3/5:4 (native) causes the aim to be off. Severity depends on the aspect ratio.
The shotgun shell ammo obscures the gun viewmodel.

1. Changing the aspect ratio:
Replace all instances of AB AA AA 3F with 39 8E E3 3F for 16:9 aspect ratio.
For other aspect ratios, see here: http://www.wsgf.org/article/common-hex-values
2. Changing resolutions:
You can replace the following resolutions by replacing the bold hex values with the hex values of your Desired Resolution :
640x480 ==> 80 02 00 00 C7 86 04 01 00 00 E0 01
800x600 ==> 20 03 00 00 C7 86 04 01 00 00 58 02
1024x768 ==> 00 04 00 00 C7 86 04 01 00 00 00 03
Replacing 1280x960 and 1280x1024 is a bit tricky. Search the hex value below:
[960,1024] x1280 ==> C0 03 00 00 EB 0F 83 F8 04 75 14 C7 86 04 01 00 00 00 04 00 00 C7 86 00 01 00 00 00 05
Now, C0 03 is for 960, 00 04 is for 1024 and 00 05 is for 1280. So the horizontal pixel value must be common if you change the resolution.
Here's a screenshot of the hex values of the resolutions:
Now set the resolution you replaced in your game launcher. That is, if you replaced 640x480, then set it as your game's resolution in the launcher.
Removing the crosshair/ mouse cursor:
Download this file [Source of the file]
Paste the file in the "fs" folder and replace the original.
Crosshair will be invisible now and it will be much easier to aim without distraction and confusion now.
