Here are some files, tools and tutorials which were crucial in developing KeeperFX.
I wouldn't be able to "synchronize" my source code with the original binary data without a good disassembler. After some research, I've chosen IDA Pro - it's a great tool, and with additional plugin it can even generate pseudo-C code for some functions.
Here are the IDA Pro projects which I made from Dungeon Keeper executables:
Note that these are not exactly IDA projects, but executables which you can load in IDA and IDC scripts to re-create function names and type definitions. There is also a readme file which explains how to properly load the IDC file.
Here's a collection of mentor scripts. Based on these, you may create or record a script for your language. Note that SVN repository contains latest version of the scripts, and also the .PO files which allow even simpler translation.
You can download a pack of PNG files which can be used to generate graphics files for KeeperFX. To generate the files used by the game, you have to place the "gfx" folder downloaded here into KeeperFX repository (downloaded from SVN), and invoke "make pkg-gfx" before "make package".
The launcher uses wxWidgets library, and you need it in order to re-compile it from SVN. If you're not interested in making your own build of the library, you can use the selected static libraries published below. They're enough to re-compile the launcher. Just place them into "wx" folder inside the launcher project.
And here is my tutorial for EXE-to-DLL file hacking
To be able to understand the Bullfrog Engine structure, I searched for executables from Bullfrog's games which would contain Debug Information block. Debug Info usually contains names of functions, which is extremely helpful in determining how the code works.
Here is a pack of all executables with Debug Info I could find. There are also scripts that allow to extract these debug information, which allows to load it into a debugger.
Please report any problems or dead links.
Read README file before using any of the programs!
