Maybe I am just doing it wrong, but
_NT_SYMBOL_PATH=. winedbg warzone2100.mdmp
doesn't change anything... (Even supplying the full path doesn't.)
The exe (not all dlls, because I don't have a copy of the user's system) is of 
course in the working directory.

That only shows me the memory ranges of some modules. The minidump includes 
more info, like the paths to dlls and similar. I am not sure whether it 
includes version information, but it certainly contains the commandline used 
to start the app.

How do I do this? And what will it provide? I tried
winedump -G warzone2100.exe
but I have no idea what I shall do with that tremedously long and cryptic

If the general debug info worked, that would also show me the function
