TETRIS (TENGENS VERSION) To select any level up to 17, pause the game with the Start button, and then enter this sequence on the control pad: up, down, up down, left, right, B, B, and A. To convert any piece into a long red bar, pause the game and enter this sequence: up, up, down, down, left, right, left, right, A and A. Though this always works the first time it probably wont work the next time, if not then just try entering the sequence again.
