Mounting multiple games
The following short section of code allows you to mount additional files from the following games:
- Counter Strike Source,
- Hl2MP,
- Episode 1,
- Day of Defeat Source,
- Half Life 2 (fixes),
This code will now fix bugs which may be featured with a game, also this allows you use the CS:S and DOD:S etc maps.. Though the info_player_*** will not work, you'll have to bind that to the original info_player_start which isn't hard.
Firstly for cdll_client_int.cpp (CLIENTSIDE)
Go to about line 622 (EP1) or line 710 (Orange box beta) - after the big list of conditions to return false in CHLClient::Init - and paste this:
	filesystem->AddSearchPath("hl2mp", "GAME");
	filesystem->AddSearchPath("hl2", "GAME");
	filesystem->AddSearchPath("episodic", "GAME");
	filesystem->AddSearchPath("dod", "GAME");
	filesystem->AddSearchPath("cstrike", "GAME");
	filesystem->MountSteamContent(-220);
	filesystem->MountSteamContent(-320);
	filesystem->MountSteamContent(-300);
	filesystem->MountSteamContent(-240);
Now open GameInterface.cpp (SERVERSIDE)
About line 551 (EP1) or line 567 (Orange box beta) - after the list of conditions to return false in CServerGameDLL::DLLInit - and paste this:
	filesystem->AddSearchPath("hl2mp", "GAME");
	filesystem->AddSearchPath("hl2", "GAME");
	filesystem->AddSearchPath("episodic", "GAME");
	filesystem->AddSearchPath("dod", "GAME");
	filesystem->AddSearchPath("cstrike", "GAME");
	filesystem->MountSteamContent(-220);
	filesystem->MountSteamContent(-320);
	filesystem->MountSteamContent(-300);
	filesystem->MountSteamContent(-240);
Compile or rebuild and run your game.
 Note:This now works in debug mode, you have to "negate" (Put a - sign in front of the number) the AppID (Thanks to Tony Sergi - Aka Omega for this fix :D)

You can also select how the path should be added to the directory table, to affect the priority given to files of the same name:
filesystem->AddSearchPath("dod", "GAME", PATH_ADD_TO_TAIL); //Add to the Tail
filesystem->AddSearchPath("dod", "GAME", PATH_ADD_TO_HEAD); //Add to the Head
