HaloMods "Classic" Read-only Archive

As the topic says, I need help extracting models and other files from HaloPC. I haven't seen a tutorial or guide on doing this, and I haven't seen mention of a program that can extract either. I know there has to be one, because of all the editing that is done on the models, but I cant seem to find info on what this program is. Also, does this program extract them into a useable file type? o-O

And, how do you open the .map files inside of HaloPC? I opened up the CAB files, and it has all the maps in the game, as well as the sound files, but they are all in a file type called a .map. How do you open these?

Thanks!

Sorry for the double post, but I am still in need of help with this.

use hmt to extract the model, then use milkshape to edit it

To open the .map files, use HMT (Halo Modding Tools). Check the files forums
