Cry of Fear Linux Patcher

A patcher for Cry of Fear on Linux, addressing various bugs by replacing game build and engine libraries with patched versions. The patcher automates the process, making it easier for users to apply the necessary modifications. Written in C++.

Usage

Prerequisites: git

To use the patcher follow these steps:

• Clone the repository:

  git clone https://github.com/hinqiwame/cof-linux-patcher
  

• Navigate to the cloned repo:

  cd cof-linux-patcher
  

• Grant patcher executable permissions:

  chmod +x cof-patcher
  

• Run the patcher:

  ./cof-patcher
  

The whole process will look similar to this:

[kys fedora ~/Coding/C++/cof-patcher] $ ./patcher
[~] Enter your FULL path (should begin with /home/) to Cry of Fear installation: 
/home/x0/.steam/steam/steamapps/common/Cry of Fear

Patcher assumes that you have installed Cry of Fear along with the Proton 5.13-6.
The patcher will prompt you to enter the FULL path to your Cry of Fear installation (should begin with /home/). After entering the path, it will check the directory's existence and proceed with the file replacements.

If you install Cry of Fear through official Steam client (not flatpak or whatever), typically the path is /home/your_username/.steam/steam/steamapps/common/Cry of Fear.

Optional Arguments

• -h, --help: Display the help message and exit.
• -v, --version: Display the version of the patcher build and exit.

Patched files

The patcher replaces several files to improve the Cry of Fear experience on Linux. Here's a summary of the modifications:

1. cof.exe - Replaces the main game executable. It is an official patch from Team Psyksckallar. Uses x64 bit instead of x32, makes the game generally much more stable.
2. opengp32.dll - Used for dynamic lighting in the game. References to it are corrected in /hw.dll and /cryoffear/cl_dlls/client.dll. Wine may lack the wglGetDefaultProcAddress function. To address this, I've patched Cry of Fear's opengl32.dll by changing occurrences of jne(75) to jmp(EB) at the specific addresses:
