 Although the connection to the rest of the Megaman (Rockman) series  is rather dubious, the creators have commented that all of the games  are (tenuously) connected. The Megaman series takes place is 20XX  (later became 200X), the X series takes place in 21XX (implied to be  22XX in later games), and the Legends (Dash) series takes place in  56XX. However, other than the creators saying so, there is very  little that connects the events of Legends (Dash) to the events of  the previous series, although there are little things like a poster  of Zero and a TV show with the original Megaman and Protoman.
