I finally figured out how to make almost any *mod* work for the xbox version of Morrowind. It so damn easy, can't believe I didn't figure it out earlier. Anyway, here it is. Copy the Morrowind.esm file to your hard drive. Rename it to Morrowind.esp. Open the newly renamed Morrowind.esp file in MWEdit, and set it as active. It loads everything from the esm file as if it were a mod. Do whatever mods you wish to it, and save it to another place on your hard drive. Rename it BACK to Morrowind.esm, and replace it with your xbox's Morrowind.esm files in both the save game file, and in the main file. I still have to figure out how to get building in there, but when I do I will post it. If anyone else figures it out, please let me know.
