Battle Unit Zeoth Cheats (GameBoy)

Wait until the music on the Title screen stops, then press Down, A and B at the same time
very quickly and repeatedly. Occasionally, you will hear a tone. Keep this up until you
hear the number of tones that matches the stage number you want to skip to (three tones
for Stage 3). Then press Start. If you hear six tones and press Start, you will see the
end of the game.
