Marios Star Quest 2

Mario's Star Quest 2 is an upcoming ROM hack of Super Mario 64 DS being developed by Oreo, which is a sequel to Mario's Star Quest. This hack plans to replace each and every single vanilla area from Super Mario 64 DS and feature new elements, such as new objects, new designed power ups, story elements and more. The overall content of the hack is expected to be about six times larger than its prequel, Mario's Star Quest, in terms of power stars and about ten times longer in terms of playtime (when trying to complete the hack for the first time).

Plot
After traveling through the lands of Mario's Star Quest, Mario receives a letter from Princess Peach telling him to come to her castle. Mario goes to the castle to find out that Bowser has stolen the Eternity Star, the star that holds an extreme amount of power that secures life for every single creature, as long as it's not on evil hands, which is not the case in this situation, as Bowser uses its power to become Dark Bowser and conquer the universe. To save the Eternity Star, Mario travels with Peach to Bowser's new castle, The Dark Castle. Once arriving in the Dark Castle, Mario finds many warp pipes to different worlds, containing stolen stars from the Mushroom Kingdom. Mario has to go to all these worlds and get enough stars to face Dark Bowser in his own world, The Dark World, only then to see his extreme form. Will he be able to save the universe from this cosmic disaster?
