The hook has now been updated to dump the xml values from the exe into the mods\Settings directory when it is first run.
On subsequent runs the xml values are loaded in to the exe before it is started.
So you can now change all the xml values without needing to change your base install or run the patch.
As the files are loaded into fixed memory areas in the exe you must not exceed the original length of the file. You can usually remove some comments etc if you need extra space after your changes. The hook will warn you if you have exceeded the original length and not load the xml in.
