Robotech Remastered (also digital remastering and digitally remastered) refers to changing the quality of the sound or of the image, or both, of previously created recordings, either audiophonic, cinematic, or videographic.
The Robotech saga was remastered and re-released in early 2004 by ADV Films, with a new sound mix, updated opening titles for the three generations, and re-added scenes.
That is the version included on all subsequent releases.
