-bphook is a command line parameter you can run wRobot with.
A shortcut is created by wRobot with the option enabled when you first run it. It's in the wRobot root folder called "wRobot No Edit Memory", which runs wRobot with -bphook. You can also rename wRobot.exe to something else in the event they're somehow leveraging warden to scan for process names. Just rename wRobot and run it, it'll generate the shortcuts just like you ran it as the original filename.
