This game has a hidden sound test.
Get a game over and when the game over tune plays (or right before it ends), hold S + C + D + T until the sound test appears. Use the directional keys to select and play the sounds.
While playing, hold the Select key and press Stop. You'll see some numbers appear in the score area. Use the directional keys to increase or decrease the numbers which in turn will modify the colors in the entire game.
While playing, press the Stop key to pause the game. Now, hold the Select key and press the directional pad to adjust the screen centering.
