Compiling under VS2002

I have tested out compiling under Visual Studio 2002 Pro and it works! Here is what you need to do...
The project files are saved as VS2003 project files so you will need to edit the following files in notepad.
For the solution file src/Game_sdk.sln
change the first line from ...
Microsoft Visual Studio Solution File, Format Version 8.00
... to ...
Microsoft Visual Studio Solution File, Format Version 7.00
For the C++ project file src/cl_dll/client_sdk.vcproj
change the version on line 4 from ...
Version="7.10"
... to ...
Version="7.00"
And finnaly for the C++ project file src/dlls/hl_sdk.vcproj
change the version on line 4 from ...
Version="7.10"
... to ...
Version="7.00"
Then open the src/Game_sdk.sln
file in VS2002 and compile the solution. This process worked for me. --Created by: X 17:57, 1 Sep 2005 (PDT)
A program on Code Source entitled "Visual Studio Converter 2.0"[1] will also do the trick to convert from 2003 to 2002 VS file format.
