Another unnamed listing was also published in a special feature entitled "Sonic Boom". It plays a short piece of music.
''Amstrad Action'' neglected to mention that the Basically Basic listing and ''Mini-Cars '' do not work on CPC464 machines, due to their use of commands that are only available in BASIC 1.1.
''Parrot'' is a modified version of a listing that was published in the book ''[[Sensational Games for the Amstrad CPC464]]''. This was confirmed by a reader who wrote a letter to ''Amstrad Action'', which was published in the [[Amstrad Action, Issue 104, 1994|May 1994]] issue (#104).
