Okay, for all of these you need to do the following first -- 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, hit Ctrl-Tab to bring up the console in which you type the cheats.
Ctrl-Tab will also close this console. Type in the cheats exactly as they
