Rockman Complete Works is a series of ports of the first six Rockman games released in Japan for the PlayStation console. New features include graphical improvements (including menu updates and new title screens), a new "Navi Mode" hint system, and Rockman 4-6 feature a full arranged soundtrack. They were later released as PSone Books in 2003. All six were released together with Rockman X7 in the Rockman Collection Special Box for the PlayStation 2, also only in Japan. The Mega Man: Anniversary Collection contains some of the new content from the Rockman Complete Works games, and was localized for different regions.
A Navi Mode and a difficulty select for all the games. In the Navi Mode, the player can receive hints when pressing the select button in areas where an exclamation appears.
Mini-games in each entry, like a Boss Time Attack (Rockman 1-3) and a Mission Mode (Rockman 4-6).
Eight new unlockable Power Ups, only available in Navi Mode.
The ability to play as Rockman without his helmet at will; simply hold R2 when selecting Original or Navi Mode.
An unlockable Sound Room option that allows you to listen to all the music from the games.
In the Rockman Complete Works version of Mega Man 4 to 6, there are eight power-up parts that can be unlocked by obtaining battle data for the game's database. They can only be used in Navi Mode and Mission Mode, and Mega Man can equip two at a time.
