I have sent you a friend request in case if you are interested so we can talk more about VCD stuff.

That is surely possible.
It depends on how much was changed from the original map.
I think he mostly added some kismet stuff as i remember in that map.

I also remember that he modified No Mercy as well that was made by Purple Parrots also and changed the wall textures much later what somewhat destroyed the nostalgia of the map when i first played it some years ago.

Any chance you could do a faithful reupload/recreation of Purple Parrot's Caged that doesn't add a bunch of stupid stuff like A JANITOR's version does?
