GameMenu.res ignored

I’m trying to modify the GameMenu.res file. Normally that file controls the options you have when you start up the game or press ESC ingame. (Play Singleplayer, Load Game, Play Multiplayer, etc.)
The problem is that whenever I open up GMod, that file gets overwritten with the file from the gcf. So all my changes get overwritten. Does that mean I can’t modify that menu in GMod?

I think you should modify one in .GCF also.

Because we can all do that.

Ahh right, steam will redownload .GCF, am I right ? I never tried to modify .GCF tho.

You can’t modify .GCF. Nobody has found a way to do it.
