+# FortPatcher
+
+This project is designed to modify the FortniteClient-Win64-Shipping executable for two purposes:
+
+1. **Run the executable in headless mode**: Ideal for setting up game servers for hosting.
+2. **Apply bug fixes**: Automatically detect the game version and apply the corresponding patch for that version.
+
+The patcher works by detecting the game version and applying byte modifications to the executable based on pre-defined patterns for different versions.
+
+## Features
+
+- **Headless Mode**: Modify the executable to run without any gui or directX requirement (nullrhi).
+- **Bug Fixes**: Automatically apply version-specific bug fixes by replacing specific byte patterns in the executable.
+
+## Usage
+
+1. Run the patcher.
+2. Select one of the following options:
+   - **Option 1**: Modify the executable to run in headless mode (for game server hosting).
+   - **Option 2**: Apply bug fixes based on the detected game version.
+   
+3. The patcher will guide you through selecting the correct executable and will apply the necessary modifications based on your choice.
+
+## How to Contribute
+
+To contribute new patches for different game versions, follow these steps:
+
+1. **Identify the game version**: Determine the version for which you want to create a patch.
+2. **Add a new version entry** in the `GetVersionSpecificBytes` function:
+   - In the function, create an `else if` block for your version.
+   - Replace the periods (`.`) in the version with underscores (`_`).
+   - Add the corresponding old and new byte arrays that need to be replaced.
+
+### Example Contribution
+
+Suppose you want to add a patch for version `6.10`. You would modify the `GetVersionSpecificBytes` function as follows:
+
+```csharp
+else if (arrayName == "bytesold_6_10")
+{
+    return new byte[][]
+    {
+        new byte[] { 0xAA, 0xBB, 0xCC }, // Old byte pattern 1 for version 6.10
+        new byte[] { 0xDD, 0xEE, 0xFF }  // Old byte pattern 2 for version 6.10
+    };
+}
+else if (arrayName == "bytesnew_6_10")
+{
+    return new byte[][]
+    {
+        new byte[] { 0x11, 0x22, 0x33 }, // New byte pattern 1 for version 6.10
+        new byte[] { 0x44, 0x55, 0x66 }  // New byte pattern 2 for version 6.10
+    };
+}
+```
+
+3. **Test your changes** to ensure that the patch is applied correctly for the specified version.
+4. **Submit a pull request** with your changes and a brief description of the patches you've added.
