I believe Candy Château is completely different, the rest not so much. I get the feeling that there were more differences during development but there was a directive to harmonize the versions, which is why Allegro Presto is so ridiculous.
Although at least they must have used different translators: "The Forgotten Swamps" is infinitely more pleasing to the ear than the name it got stuck with in the English version on other platforms, which I won't repeat since it's quite probably the greatest insult to the language of Shakespeare I have ever seen in a commercial work.
