Oh definitely upload the fix. At most I can pick it apart and learn something from it. Since the SFCFix Tool doesn't seem to have an in-depth guide for scripted fixes, I have nothing but a guess as to how they work. I am curious to see if I am correct as I have never seen one of the fixes yet.
Educated guess on my end is the fix is just a folder with proper structure including manifests, dlls, etc that is packaged into a zip. When renamed SFCFix.zip and ran with the SFCFix Tool it uses those files to replace damaged ones. Claims files, replaces, reverts permissions, checks again, done etc.
