Theme - Ninja Scooter Simulator (C64)
Theme starts every time you enter the main menu (but not a new high score, which is on the same screen). It stops if you choose FX ONLY and level 1 appears.
Theme was recorded from a real PAL C64C with an 8580 R5 4091, but sounds the same on every SID chip.
The bass and main section are more rock-flavored. On channel 3, arpeggiated chords and sweeping-down snare drums are played by a 25% pulse wave.
Channel 2 starts off with white noise drums and 4 steely notes: 3 on pulse wave, and the 4th on a quieter triangle wave.
After 2 loops, it switches to a trilling melody, which changes key signature so much that some people perceived it as out of tune. This section sounds a bit circus-like.
After 2 more loops, the song transposes 2 semitones down, and channel 3 one octave up again.
All instruments except for gongs have a slight vibrato.
