Of Couse, all the cheats from the original Baldur's Gate work too
 with the expansion.

 File Editing

 Open the file Baldur.ini in your Baldur's Gate directory and add the
 line Cheats=1 under the [Game Options] entry. Then save the file and
 run the game.
 Once in the game, press [Ctrl][Tab] to bring up the console in which
 you type the cheats.
 Type in the cheats exactly as they appear below and hit [Enter] to
 activate. Close console with [Ctrl][Tab] again.

 After editing the Baldur.ini file in the Bgate directory, (as was
 done for the other cheats), you can use the following codes:

 CLUAConsole:CreateItem("xxx") where xxx is the code for an item. For
 an entire list of all items download the Baldur's Gate Item List file.
