Replace game files

This guide gives you three methods of how to replace the game files from data.bcp with your own modifications. Note that there are differences between the first WK and WK Battles in how they load the BCPs. While the second method works for both WK and WKB, the first one is recommended for WKB because it uses less disk usage.

The unofficial patch now allows you to use the WKB method for WK, plus it adds a third method compatible with WK and WKB: the "data" directory.

Patch BCPs

If you have the WK Battles, or first WK with unofficial patch, you can make “patch” BCP files (like patch_1_1.bcp) that only contain the modified files. When you copy the patch BCP into WKB’s directory, the game will find it, load it and use the modified files of the patch BCP instead of data.bcp.

    1. In the modding kit go to “BCP Packer/input”.

    2. Copy your modified files into this directory. Note that you will also need to make new directories to keep the file’s path in data.bcp. For example, if you want to change “Interface/FrontEnd/Warrior Kings Logo.tga” then you need to make the directory “Interface” in “BCP Packer/input”, then make the directory “FrontEnd” in “BCP Packer/input/Interface” and then copy your modified “Warrior Kings Logo.tga” into “BCP Packer/input/Interface/FrontEnd”.

    3. In “BCP Packer” directory, double-click “Pack Input Folder to BCP (WK - B).bat”.

    4. You should now see a new file called “yourbcparchive.bcp”. Rename it to what you want.

    5. Copy your BCP file into WKB’s game installation directory.

Now when you run the game, the mod should take effect. If you want to stop using it, simply move your BCP file into another directory (for example the desktop), or delete it.

Creating a whole new data.bcp

For the first original Warrior Kings without patches, there are no other choices than making a new whole data.bcp.

    1. Extract all the files from “data.bcp” (see “Extract data.bcp”).

    2. In the modding kit go to “BCP Packer/input”.

    3. Copy all the extracted files (content of “bcpxtract”) into this directory.

    4. Make some modifications to the files.

    5. Go to the “BCP Packer” directory and:

      1. If you use Warrior Kings v1.0 – v1.3 (published by Microïds), double-click “Pack Input Folder to BCP (WK).bat”.

      2. If you use Warrior Kings v1.4 (published by Empire Interactive, Strategy First, or downloaded from Steam, GOG), double-click “Pack Input Folder to BCP (WK - B).bat”.

    6. You should now see a new file called “yourbcparchive.bcp”.

    7. In WKB’s game installation directory rename “data.bcp” to “data_original.bcp”.

    8. Copy “yourbcparchive.bcp” into WKB’s game installation directory and then rename the copy to “data.bcp”.

Now when you run the game, the mod should take effect. If you want to stop using it, rename your “data.bcp” or move it into another directory (for example the desktop), then rename “data_original.bcp” back to “data.bcp”.

"data" directory (requires unofficial patch)

In the game's directory (with the exe), create a directory named "data". Now you can copy new game files into this directory. If a file is present in both data.bcp and data directory, the one from data directory will more likely be loaded if its modification data is more recent.
