Crouching Tiger Hidden Dragon 2003 (set 1) is a hack of The King of Fighters 2001, an arcade fighting game. While details on the specific creators of this hack are scarce, it leverages the engine and assets of the popular KOF 2001.  Gameplay likely maintains the core fighting mechanics of KOF 2001, but with characters and perhaps story elements themed around the Crouching Tiger, Hidden Dragon movie.  The 'set 1' designation might imply multiple versions of the hack exist.  Given its hack origins, it was not produced by SNK Playmore (the original KOF developers) but rather by an independent member of the fighting game modding community.
