How come only the packed version of the Buldge Bomb works for me, where as the others won't even open?
   The packed version may work for you, where as the others may not because the packed version is a program that does not require any unzipping programs. You will need to download some unzipping software, along with winrar. I suggest winzip to unzip the buldge bombs. You can download winzip here, and winrar here.
