1. Downloaded ArmageTron 2.1 source for Windows.
2. Downloaded ArmageTron 2.6 source.
3. Un-archived the 2.1 source and read the readme.txt
4. Renamed the Armagetron folder to Armagetron-2.1
5. Un-archived the 2.6 source into the folder of the other source.
This gives a directory listing of:
armagetron <-- this is the 2.6 source folder
armagetron-2.1
debug
dist
libs
libs_binonly
At this point I followed the instructions in the readme, as follows:
6. Copied the dll's from the libs_binonly folder to both the debug and armagetron\build folder
7. Copied ALL of the files from the following folders to both the debug and armagetron\build folder
- arenas
- config
- language
- models
- sound
- textures
8. Created a "var" folder, and another in the armagetron folder
9. Finally, I opened armagetron\VisualC\Armagetron.dsw
Unfortunately, there are some problems. No source files are loaded. Not surprisingly, it also won't build -- everything in the Build menu is grey. So what I did was insert a project for this workspace, choosing the armagetron.dsp file. At this point I get the following error message:
"This makefile was not generated by Developer Studio."
It lets me create a new Developer Studio project to wrape the makefile, though, which I do. This doesn't get me any closer.

Does anybody have an idea of where I went wrong?
