In 2004, an unlicensed remake of the original F-1 Spirit was released by Brain Games, chiefly for the 2004 Retro Remakes competition [REF].
This remake retains much of the gameplay and content of the original, but with changed physics, a number of sound and graphical improvements (some of the latter make the game resemble titles such as F-1 Grand Prix), and online leaderboards.
