They are just some extras added into the game, I am fairly sure that info is accurate, hope I answered your question.

but what are those extras?

They are all right in my other post, just read the info I quoted from the site.

Ok, I redesigned it so perhaps you can read it more clearly.

but what post you talking about?

Its the third post on this thread, its all 24 of the treasures, and how to obtain them.
