[SOLVED]MW2 Steam Files

I wanna try make hacks for steam version not alteriwnet, so i need the following latest files below:

iw4mp.exe
aIW.dll
aIW-xmpp.dll
steam_api.dll

If i missed other important files please added it too to attachment.

Thanks for your help

The Steam version does not come with aIW.dll or aIW-xmpp.dll! I added SteamAPIUpdater.dll and UpdateDLLWrapper.dll. Not sure if they are important though.
