Receive the Bad Ending.
To get the Bad Ending, you must be playing as 2 players. You must also be in 2 player mode before Level 8 or else player 2 can't come into the game on Level 8. When both players reach Mr. X in the final room and he asks his question, make sure one player answers yes and the second answers no. Mr. X will have both players fight each other to the death. Have one player lose and choose game over. Afterwards, Mr. X will ask a second question. Be sure to answer NO to that question as well to trigger the final boss battle. When you beat him, you will become the Boss. NOTE: If you answer yes, you will again be shut back 2 levels and still not be ale to get the bad ending.
