Classic mode: Enter the "Marathon" option at the main menu,
then hold L and press Select. Enter the Marathon
screen and select the "Popular" option to play the classic
version of Tetris. Note: L and R will move
the piece left and right.
No music: When you go to the screen after you select "Popular
mode" but before you actually start playing, press L
+ R + A. You will enter the original game without
the music, but you still have sound effects. Note: When the game
ends, the screen freezes requiring the Game Boy Advance to be
turned off.
