Updated on op too btw.
Yes, you need the untouched files. That's why the patcher makes a backup of them in the "original" folder it creates and ask you to move it to a safe place.
But if you are already on 0.9.1 you'll only need to repatch pack_030_etc, pack_031_message and pack_999_lua which take little time to finish. You can copy only the needed patches to the "xdelta" folder inside the patcher and ignore the warnings of the patcher.
pack_050_movie is optional as only fixes a minor error about Tsubasa age in the intro movie (in the newspaper says she is 13, fixed to 12 in the updated patch).
