HaloMods "Classic" Read-only Archive

first of all sorry no pic.
I made it in milkshape 3d, and i was wondering if possible how would i import it into halo or halo 2. or how would i get a 3d modle out of halo so i could skin it myself. i would appreciate all the help possible.

so i started messing with it after i posted this topic and i looked to see what the original hex value was and changed it to that and it went in but multiplyed and got distorted. the files were the coag_ring, and coag_moon.

Ok, I extracted a .dds fill converted it, modified it, converted it back, and I got an error saying that it has to be DXT1, so I open it up in the Hex view, and it says that it is DXT1. I'm a little confused! If anyone would be so kind I would greatly appreciate it.
