Patch applier

[ghost]

I don't know if you had intentions to do it or not, but I wrote a simple C# code to replace the engine2 string in hlvr.exe with hlnonvr:

   internal void ApplyNonVRPatch()
    {
        string fullPath = installPath + "\\game\\bin\\win64\\hlvr.exe";
        Dictionary<int, string> strings = new Dictionary<int, string>();

        byte[] byteArray = File.ReadAllBytes(fullPath);

        List<char> chars = new List<char>();
        for (int i = 0; i < byteArray.Length; i++)
        {
            byte b = byteArray[i];

            if (b == 0 && chars.Count > 0)
            {
                string word = new String(chars.ToArray());
                strings.Add(i - word.Length, word);
                chars.Clear();
            }
            else if (b > 0)
                chars.Add(Convert.ToChar(b));
        }

        strings = strings.Where(x => x.Value.Contains("engine2"))
            .ToDictionary(x => x.Key, x => x.Value);

        foreach (KeyValuePair<int, string> kv in strings)
        {
            string value = kv.Value.Replace("engine2", "hlnonvr");
            char[] charArray = value.ToCharArray();
            for (int i = 0; i < charArray.Length; i++)
            {
                byteArray[kv.Key + i] = Convert.ToByte(charArray[i]);
            }
        }

        try
        {
            File.WriteAllBytes(fullPath.Replace("hlvr.exe", "hlnonvr.exe"), byteArray);
            File.Copy(AppDomain.CurrentDomain.BaseDirectory + "/Tools/HLnonVR/hlnonvr.dll", installPath + "\\game\\bin\\win64\\hlnonvr.dll");
        }
        catch (Exception) { }
    }

It wouldn't actually be "distributing valve code", and it would call out people who are afraid to use a hex editor.
