Superpack

Could someone please explain me what the difference between the normal client (found in robocode/robocode.bat ) and the Roborumble Superpack (found at http://robowiki.net/wiki/RoboRumble/Starting_With_RoboRumble#With_the_Roborumble_Superpack ) are. Is the second one better ,faster? Everytime I try to download the superpack from the wiki I get a Dropbox 404 error ,so I downloaded it somewhere else, but after I unzipped it , I only found roborumble.sh and twinduel.sh. I have some Linux distrutions installed on my system, but I almost never use them. So where can I get a superpack for Windows? Thank you.
