The boot music is the famous jingle played during the eyecatcher at startup, and often during the attract sequence.

The music is only played when the flag byte at $114 is = 0. The System ROM always uses code 2 to play it.

Many games remap and/or add instruments (different instruments in Blue's Journey, drum loop in Neo Bomberman for example), but all games seem to use the same melody.

The original music is FM only and uses all 4 channels as 2 pairs of "echo" channels (2 melodies only, each being played with a slight delay). It's played at 192 BPM and uses down to 1/32 notes.
