Find game files (main, zone) from current working directory rather than where the binary is

[PureTryOut]

I'm trying to optimize my server setup and part of this is moving the game executable (cod4x18_dedrun) to a common bin directory with other executables. I have this directory added to my $PATH so I can execute it from everywhere but CoD4x (well, vanilla CoD4 as well) seems to search for the other game files in the directory where the executable is rather than the current working directory.

So say the executable is ~/.local/bin/cod4x18_dedrun and the current working directory is ~/game_server and has the main and zone folders, it currently looks for ~/.local/bin/main and ~/.local/bin/zone rather than ~/game_server/main and ~/game_server/zone.

It would be great if it could look for the files it needs in the current working directory, or maybe even change the location using an environment variable.
