Classic NES Series: Castlevania Cheats (GameBoy Advance)

Succesfully complete the game under the normal difficulty setting.

On the title screen, let all three demos cycle through then start a new game or continue a
saved game. The background music won't play. To disable this, you can either lose a life,
fight the boss of the level, or reset the game. Note that when the demos are cycling by,
don't skip them. If you do, the glitch won't work.
