Mountain Palettes being moved and overlay help!

Ok! So at first I thought I could avoid this but at this point I really just need someone to help me with this because it's difficult without. I need to know if the palette data for the mountain area can be moved to a different map? This map is actually Area 00 which is the forest map which might be problematic because of the forest overlay BUT I don't want the overlay gone I want to replace it with the parallel worlds snowing overlay!

I could easily implement the graphics for the snow if someone showed me how I just need the colours from the mountain moved to Area 00 since if you haven't already guessed its a snowy mountain area! I've been just working on the tileset for the mountain lately but now as I'm getting close to finishing it up with a few minor things like entrances being addressed I'd like to see if anyone can help me with these things  

Also sidenote: where's everybody been lately? Just busy or something, the forum isn't nearly as lively as it usually is

The goal:

Patch world colour loading to be area dependant.

This note includes all the changes done to the rom in the .ips patch, and their locations.
Just in case it needs to be moved later on etc, keep this note with the patch.


Notes:
- all Hex offsets in this note are for headerless rom.
- Patch file is for a HEADERED rom. As the original supplied rom was headered.

world color 1 pal 0 is light world non death mountain areas (areas other than 3,5 and 7)
world color 1 pal 1 is dark world non death mountain areas (areas other than 43,45 and 47)
world color 1 pal 2 is light world death mountain areas (areas 3,5 and 7)
world color 1 pal 3 is dark world death mountain areas (areas 43,45 and 47)

Map 1, indicates which pal to use, only proven to work with 0,1,2,3.

^^Your request is exactly that patch! With it it's possible to attribute any area colors you like to any of your areas!

Don't know anyone else status, but on my part I've been etremely busy with real life lately and had no rom hacking time at all

The link to this is broken, any mirror?

You can find this patch in my conker asm files pack, which you can find here:
