I have extracted pathfinder W3ds (all of them!) and Skins and changed ther file names.
eg) AIPFDR_SKN.W3D -> NIHONG_SKN.W3D
All file names should be modified.
Note that AIPFDR and NIHONG are 6 letters long.
Then I open all of the w3d with Ultra Edit.
I have used Search and Replace to replace AIPFDR to NIGHONG.
Now for skin, I've searched for ZHCA_AIPthFindr.tga and replaced it with ASDF_AIPthFindr.tga
It worked
