I have uploaded source code here: http://irrlicht.at.ua/load/0-0-0-2-20
ZIP contains only c++ source code and vs2005 sln and vcproj files (no conf file and data folder).
To compile it do next:
- copy data folder and conf file inside;
- forWindows/vs2005: open sln and setup path to Irrlicht.lib and Irrlicht' header files in project settings, also copy Irrlicht.dll 1.6.1 to output folder.
- forNonWindows: comment out #define GAME_WIN32 in ff/graphics/GameGlobals.h; that should be enough, but i haven't compiled it on linux personally.
- if you want to get FPS camera and other dev-stuff i used -- comment out #define DEMO_MODE in CastleWalker/main.cpp; use SPACE to switch FPS camera control.
