Jonathan "Joffa" M. Smith (1 February 1967 – 26 June 2010) was a British games programmer, best known for his titles for the ZX Spectrum. His games were notable for containing a large number of sprites and parallax scrolling, features which were largely unknown on the Spectrum at the time.
His most notable games include Cobra, (which was a license extremely loosely based on a Sylvester Stallone film) one of the first Spectrum games to exhibit full-colour parallax scrolling and his conversion of the arcade game Green Beret. A notable "trademark" of Smith's was his habit of writing his name (with "Jonathan" and "Smith" spelled various ways) as a mirror-image in his games.
