Speaking of Tactics Advance, Hardedge is a greatsword of similar design on there that seems to be an intentional reference. Also Fire Veil is a Ninja Skill. So...
I agree with you on Hard Breaker = Hardedge.
However, Katon seems to only be called Fire Veil in FF7, Tactics Advance and A2. Everywhere else it's Flame or (as the re-translation has it) Katon.http://finalfantasy.wikia.com/wiki/Flame_%28Ninjutsu%29
EDIT: Turns out I already have Hard Breaker changed to Hardedge in the current patch. I just forgot to add some of the Weapon changes to the Google Doc (Fixed now).

Updated the first post with an updated Canon Addendum.
It is based off of the unofficial update to the re-localization patch I created here.https://dl.dropboxusercontent.com/u/47184537/Projects/FF7-Because.zip
(I hope to adopt it to whatever Green_goblin makes the next official release later).
This newest patch has all changes talked about in this thread applied.
Also, like the unofficial update to the base patch, this is a rebuilt ISO with LBA changed accordingly.
The field data has also had all unused texted cleaned out (using Makou Reactor). This should improve load times (ever so slightly).
I'd appreciate some testers.
EDIT: The damage limit has also been changed back to 9999 in the latest Canon patch. Green_goblin set it to 65000 in the base patch.
