has some one know about d2dv's files format?
Which files? MPQs can be opened with MPQ extractors, such as Ladik's MPQ Editor (http://www.zezula.net/en/mpq/download.html). The sounds and music are standard audio formats, the videos are Smacker (http://www.radgametools.com/smkmain.htm), and I believe the character info is some proprietary format (Ringo was getting into it (http://forum.valhallalegends.com/index.php?topic=14493.0) some time ago, maybe he's got more info on it).
