While on the intro screen type "SERIALINTERFACE" then while playing press 'F9' to top off Robocop's energy and 'F10' to skip to next level. Try this one as well: once loaded press 'F3' to access the high score table and type in "BAMBOOZULEM", then press 'Help'. You should have infinite energy. When you're in the shooting gallery, don't move the joystick and you will have 1,186 targets.
