While this dungeon is "A Cove", it does look exactly the same when being on a pirate ship or somewhere else. Most of the content is transported by text in this game. Will be lots of effort to transport all this into todays standards.
Or to put it in different words: You could say that if they put Shadows over Riva and Blade of Destiny into the same technology, so that they would look the same side by side, you would realize that Riva is not more of a fraction of what Blade of Destiny is.
But that is of course, because back then they didn't need to graphically visualize all the details and so it was easier to produce content.
