Final Fantasy III: Ignore Defense no longer ignoring Safe and Shell

This patch makes “ignore defense” behave like how it does in Final Fantasy 7 on up. If an attack ignores defense, safe and shell are still taken into account.

Title: Ignore defense no longer ignoring Safe and Shell

Urgency: Low, I don't think it's a bug. But since this patch doesn't account
for things that do set damage (items, Blow Fish, etc) it's hard to tell. I leave
it for debate whether or not it's actually a bug.

Description:

Final Fantasy 7 started something that the rest of the series used, and is
something that FF6 did support but for oddball reasons was not used.

Real description:

Any attack, be it physical or magical, if it ignored defense also bypassed Safe
and Shell.

--------------------------------------------------------------------------------
What this patch does:

Instead of completely blowing by all of the defense modification, it now checks
if Safe or Shell is in effect for the target.

Note: The anti patch effectively removes this patch.

Updates:

1.E - August 19, 2009

*insert Darth Vader "nooooooooo!" macro here*

After consulting with everyone known to man, I believe that this time, it does
not conflict with another patch. Hurrah!

1.D - May 31, 2009

*insert Darth Vader "nooooooooo!" macro here*

Patch conflicted with Can't Win for Losing. Code moved, *again.* The next time
this patch conflicts with anything I'll say "fuggit" and move the fix to C0.

1.C - May 30, 2009

Thanks to C. V. Reynolds for pointing out that this patch and "For What Ails Ya"
conflicted with each other. And yet again, code is otherwise unchanged. :P

Perhaps there will be no more updates to this patch? Maybe? Please?

1.B - January 18, 2008

Moved code, as it was conflicting with assassin's Alphabetical Rage patch.
Code is otherwise unchanged.

1.A - Oy, I released v1.8 and v1.9 too quickly. The carry flag was now checked
too late, and calculations would've still been thrown off.

1.9 - Added header/non-header patches.

1.8 - There was a possibility of the carry flag being tainted when it jumped
back to the original code, thereby throwing off some calculations. Should be
corrected now. :)

1.4 - Added row checks for physical attacks that ignored defense. Damage is
reduced by 50% for targets in back row.

v1.2 - Fixed a problem that would crash/cause problems if a target had
safe/shell in effect, regardless if the attack ignored defense or not.

v1.1 - Hmm, don't remember

v1.0 - It never worked... :(
