Help About Dornas

can i know which file to open and what number to edit the dorna textures..
i downloaded the texture [.dds] files but i dont know the number for the dorna and which .iff to open..

i know for the backboard you open the sXXXiff file then select the 22 and import the corresponding .dds file..

but how about dornas?.. thanks so much..
