Final Fantasy IV Advance: Defender Fix

The GBA port of this game has a few notable changes from the original SNES
version. Targeting was changed for a number of weapons that casted spells.
One of the weapon's spells has its targeting set incorrectly.
The Defender Sword by default targets the enemy with the Protect spell,
which obviously is not what you want.

A separate patch changes certain weapon behavior back to what they were
originally in the original FF4. This change in FF4A annoyed me a lot.

Why does this patch exist?
--------------------------

The GBA port of this game has a few notable changes from the original SNES
version. Targeting was changed for a number of weapons that casted spells.
One of the weapon's spells has its targeting set incorrectly.
The Defender Sword by default targets the enemy with the Protect spell,
which obviously is not what you want.

A seperate patch changes certain weapon behavior back to what they were
originally in the original FF4. This change in FF4A annoyed me a lot.

Note: To use spells that are attached to a weapon, you need to equip the weapon
first. In battle, select the Item command for the character equipped with the
weapon and hit the Up button until the equipped weapon is displayed. Select
the weapon twice and it should target like you were using an item or a spell.
Select the target and see what happens! Not all weapons have a spell.


What This Patch Will Not Do
---------------------------

This will not change any magic's targeting. Only the weapon's specialized
targeting for the spell is changed.


Weapons Affected
----------------

Defender
Ice Rod
Flame Rod
Thunder Rod
Flame Lance
Ice Lance


Patching
--------

There are patches provided for the following...

GBA - US
GBA - Euro

I hadn't bothered creating a Japanese version of these patches yet.
If someone creates it, that's nice.

You should be able to use an emulator's software patching or LunarIPS
if hardpatching is needed.

Important Note
--------------

I don't have any issues using this hack/patch as a basis for another
hack/patch, particularly if it is to be a cumulative patch fix. It would be
nice if you mention my name, but that's not a requirement.

Also, I might get around to creating a patch for both Japanese versions of
the game. No guarantees though!

JCE3000GT made an awesome complete hack (based on what was known at the
time) that got me interested in finding out more.

Dragonsbreathren for helping out when I didn't know any better way back when.
I got the inspiration for this hack from his hack.

Thanks to Lenophis for putting up with me on the forums.

Entroper wrote a pretty good FF4A doc sheet with addresses that I could find
what I needed to modify on my own.
