Applying PPF's to Halo 1 on Xbox vs PC?

[GnaM]

Normally making and applying ppf's is a pretty simple process...you just pick the proper maps and patches and click a button and it's done. However, when it comes to Halo 1 on Xbox, the maps are compressed, which seems to put a wrench in things.

I am working on a Halo 1 Xbox mod project involving modding all the original maps. I've been trying to create ppf's based on my modded maps to distribute. The only way I've been able to successfully make a patch is to open both the original map and the modded map in Dot Halo to decompress them, then close Dot Halo leaving them compressed, and then make the patch using PPF Studio or Dot Halo.

The same thing happens when I tried to apply patches to clean maps in order to test that the ppf's worked. If I don't de-compress the scource map in Dot-Halo first, the map will work on the Xbox, but won't have any of the changes that the ppf was supposed to apply.

The only way I have successfully applied a patch is to open the scource map in Dot Halo, then use PPF-o-matic, HHHT, or Dot Halo to apply the patch, then open the map up in Dot Halo again and close it to recompress the map.

I don't want users of my mod to have to download Dot Halo along with the whole .NET framework, then open, decompress, patch the map, close and compress the maps all themselves. That's a tremendous amount of work to expect from someone who's just a regular player and not a fellow modder themselves.

Does anyone know a way to patch Halo Xbox maps without decompressing them first, or a program for applying patches which will automatically decompress and recompress the maps for you?
