Scramble Formation was released in April 1986.
Despite this release period, the high score is anonymous.
Changing the language from Japanese to English in dip switches changes the title from Scramble Formation to Tokio.
The English title is misspelled - Tokio. This should have been written with 'y' (Tokyo).
The bullets fired out of aircraft are actually ASCII exclamation marks.
This game has no end.
