Final Fantasy IV Research & Development / Re: Developing a comprehensive editor for FF4
« on: October 20, 2013, 06:15:55 PM »
Here's a neat little addition that should be a very simple addition to the editor. How the game decides if the character is Yang and how to process Damage from Fight.

The code surrounding it is in my other thread, quite a bit was revealed within. But for the purposes of the editor this should suffice...

In LoRom/HiRom...

$03/9B0D   C9 00   CMP #$06   A:0000   X:FFFF   Y:0001   P:envMxdiZc - Is it Yang's ID?

This is the check for which character is considered to have special considerations when it comes to weapons.

But you could really link this special behavior to anything...

$03/9B06   A0 01 00   LDY #$0001   A:0001   X:FFFF   Y:0024   P:eNvMxdizc - Load 1 into Y.
$03/9B09   B1 80   LDA ($80),y[$7E:2001]   A:0001   X:FFFF   Y:0001   P:envMxdizc - Load Slot's ID.
$03/9B0B   29 0F   AND #$0F   A:0000   X:FFFF   Y:0001   P:envMxdiZc - Get rid of negatives?
$03/9B0D   C9 00   CMP #$06   A:0000   X:FFFF   Y:0001   P:envMxdiZc - Is it Yang's ID?
$03/9B0F   D0 03   BNE $03    [$9B14]   A:0000   X:FFFF   Y:0001   P:envMxdiZC - If not branch to 039B14.

You could have it look at specific weapons, different armors, etc.

Final Fantasy IV Research & Development / Re: Grimoire LD's Notes, Methods, and Hacks (FFI spell routines in FFIV!)
« on: October 20, 2013, 06:14:35 PM »
While looking for In-battle names in memory I stumbled upon what makes Yang unique as for how his damage is calculated. This is quite important as this is the first time I've seen actual damage formulas being compiled and created.

Well, well! Looks like DeathLike2's Formula for Yang's Attack was almost 100% on the mark! The only miscalculation was Level x2 +2 rather than +1, but its so miniscule anyhow. This is where I would normally stop and look at the collected results above, but unlike a normal routine, this just ends abruptly so I have to follow it back from the RTS. Maybe this will, in the end, reveal the location of all Attack Formula.

And there we go! I have to head out for a short while, but this should be good enough to post. It is clear now that the other attack formula are probably very nearby. Likely in between the bytes that read specifically Yang in the first bit of code above. Because clearly this second portion of code is used by every attack formula I would imagine.


And it seems I was right. The normal attack building formula is within. Though there is a lot of reference to this 3977 byte that I've erroneously called "Is it Yang?" since it seems to be used for a lot of other dealings as well.

And it would seem I was wrong all around for Critical Hits and Critical Hit Bonuses. They aren't unique to each character but it seemed that way to me because I did not think Level or Strength would play into it at all.

This did reveal two more things as well...

Bytes 41 and 42 of Character's data is Level /4 and Levelx2. When not cheating, it appears. Hence why just changing the levell doesn't actually appear to do much of anything on its own.

 :edit: And the Bow and Arrow section has been added! That only leaves dual weapons, I would think.

Deathlike 2's formula says...
Bow and Arrow (with Bow in recessive hand):
Base Attack Power = Bow's Attack Power/2 + Arrow's Attack Power + Str/4

This is entirely accurate as the data above would attest.

It appears to be Bow Attack /2 + Arrow Attack, + Str/4 = Attack Power. Testing with default Rosa shows the power of the bow is turned to 05, then the Arrow's attack is added and the Strength bonus is included.

Now for...

If the bow is in the character's primary hand...

Base Attack Power = Base Attack Power (Bow and Arrow) * 4/5

That too is 100% accurate. The game takes it through a routine which chops the main power of the attack by 1/5 in total.

 :edit: And Dual Wielding is finished which means this Formula Building should be done all in all.

The Algorithm FAQ says...


Edge (when he has both hands in use):

Base Attack Power = Weapon on Left Hand's Attack Power +
                    Weapon on Right Hand's Attack Power +
                    (Str/4 + Level/4)*2

And it was right on the dot. Weapon Attack Power + Str/4 + Level/4 * 2 is indeed the formula that is put together for this.

Final Fantasy IV Research & Development / Re: The ACTUAL targetting of commands
« on: October 20, 2013, 03:58:54 PM »
It would appear the first attempt at figuring out what commands could be targeted used a faulty method... Here is the revised list, you'll notice anything that casts an actual spell can be retargeted easily enough.

Fight - No
Dark Wave - No
Jump - No
Recall - Yes
Sing - Yes
Hide - No
Salve - Yes
Pray - Yes (It can target either allies or enemies without worry)
Aim - No
Focus - No
Kick - No
Gird - Yes (As above with Pray)
Twin - Yes
Boast - No
Cry - No
Cover - No
Peep - No
Crash - Yes
Dart - No
Sneak - No
Regen - No

Now Jump/Aim/Focus can't be made multi-attacks because they follow the same formula that Fight uses. The only difference in Focus and Jump's case is that they put on a special status which is removed when the attack resolves.. Aim is just the Attack Command with 255% Accuracy. (and 0 evasion on the enemy, but that's a moot point really)

This unfortunately also applies to Dark Wave and Kick Commands because they both derive from the same source. You could change this of course to use the magic formula (in Dark Wave's case as a way to differentiate it from Kick). Dart/Sneak/Regen are all different beasts all together, but they cannot be changed either it appears.

So while you can't change them all, everyone that uses a spell call can be easily manipulated, including Salve.

Finally found this one! I failed to find it in LoRom/HiRom/RAM in any way but I went to where the original sequence was in ROM and thought there had to be a copy of it elsewhere, so I copied the original sequence, searched and found the location in only a minute.

In Rom at...

And that should be that in regards to this matter.

Final Fantasy IV Research & Development / Re: Changing spell effects outside of battle
« on: October 20, 2013, 03:22:40 PM »
Alright, I've taken another look at this because it was important for my FFIV-FFI mod and hopefully have come up with some decent results...

Something I did not notice is that spells are aligned in such a way that their usability is dependent on a range and index 0E-1B (Game looks at 1C but it is 1B, 1C is Venom, 1B is Warp).

01B27F - C9 0E - (CMP with 0E) is actually what spells to highlight and Only what spells to highlight.

$01/B283   C9 1C   CMP #$1C   A:0219   X:0248   Y:0000   P:envMxdIzC - This is where the index of usable spells end. So if you wanted to change the index of usable spells you would change these two values to whatever was desired. When I saw the value the first time I must have confused the 1C for a 13, I'm not really sure how I did that, but eh...

And here is the actual ranges of spells as well.

01B52E - C9 0E - CMP 0E - Start of Index of usable Spells outside of battle.
01B532 - C9 1C - CMP 1C - End of Index of usable Spells (Using spells outside of their intended range tends to have glitchy and game crashing effects)

I've tried to find anything more than that, but have so far come up empty handed, I'm afraid.

Final Fantasy IV Research & Development / Re: Developing a comprehensive editor for FF4
« on: October 20, 2013, 11:54:24 AM »
Ah! You didn't mention you included the Auto-Battles! Fantastic! How much space is allotted to those? I added some more instructions to the script and saw no issues in being carried out. All that needs is the "Only this character must be present" or "This character should stay out of battle" code I found a while back. (though since that doesn't necessarily deal completely with auto-battles maybe it would go elsewhere?) Oh, and Golbez's auto-battle information. I have a feeling it will be closeby the original code, but not immediately next to it. I already have a proper search point to find them...

"389A-???? Autobattle script for second character." Thanks to the Tower of Bab-il Docs. I'll see if I can''t find those later today.

Spell Animations look to be properly ordered, no errors to be seen in those, good work in implementing them.

Ah right, and a quick question about the "Start of Magic..." in the editor. Is that referring to their formulaic properties as well? I found in the Magic code not too long ago how the game decides what kind of magic it is and how to take it into accordance when casting spells. In addition to that is also the starting point of when the game looks at Wisdom or Will to decide what powers a certain magic. I wasn't certain if the editor includes that information as well or was in some old notes I may have missed.

That is correct. In what I found is If Edward is knocked into Critical While his Turn is Active, get rid of his menu. The rest of the code assumes that Auto-Hide is running from its proper course elsewhere.

And there you have it. The way Hide works and the ways to modify it. The entire point of the Critical Check seems Purely for Edward's Auto-Hiding purpose. And the means to switch conditions (and targeting from the looks of it) seems quite a simple matter. But for the purposes of what you want to use it for, it doesn't even need to be a command. Just something that especially looks at the character and responds appropriately.

(Appears to somehow get rid of the pointer for choosing commands quite important when for an Auto-Hide dealing)


Which is the Routine revolving the activation of Edward's Auto-Hide command.




Hmm, you were quite mistaken about the Auto-Commands.

Auto-Cover looks for Paladin Cecil Specifically (any other character that uses Cover is thereby protected by the Paladin) but is disabled when the Dark Knight is present (which can never logically happen...)

Auto-Hide looks for Edward's ID, sees that it is his, and then uses the command.

http://slickproductions.org/forum/index.php?topic=1754.msg18211#msg18211

Quite old info. by this point, but I can see how those sorts of things could fall through the cracks.

Aside from Auto-Cover and Auto-Hide I can't think of any other Auto-Commands off the top of my head, unless you consider Berserk to give Auto-Fight (which is likely does)

Though the information is quite old. The new information above allows you to switch the conditions for activating Auto-Hide (in one instance. Its likely not too useful or reliable because this instance is so specific. It Has to be Edward's Turn, when he is put in critical for this instance to occur, which means there must be another instance I haven't located. Likely close to the second instance at 03AB56. I'll take a look at that a little bit later and see if that will make it work once and for all.

Yes, the freed up bytes of Peep may allow you to have something much larger. A Blue Magic command fully equipped with Learning though...? Hmm... You may be able to use the code of Auto-Hide (which I should explore fuller rather than just finding who it effects.) as a start to have it always on, so when your character is hit by those specific effects they automatically (or have a chance?) to learn said spell, since all Auto-Hide does is execute (almost without a doubt) is the (7E2X86) Auto-Hider in Critical? Then Used Command Hide. If you set up a range of Monster Spells and change that to "Is Learner being hit with a spell above say 60 (Start of Monster Spells) Then... Is the Learner being hit with a spell after 60 (18 Bytes, 24 spells to a spell set so...) is it before 78? (If either of these are untrue, return). Then add the spell directly to the spell set. IF not already there.

That seems like it might be the best way to set up an FFIV Blue Mage. I'll see about finding out more about Auto-Hide shortly.

That is some clever hacking! Fantastic work there Chillyfeez. So where is this code planned to be plugged into? The newly unused portion of Peep linked to the old 0000 of "Crashes Game"?

Hmm, yeah I noticed similar problems in using the Un-Berserked Avenger Sword. Though for the most part things seemed well in hand before trying to mimic magic outside White froze the game. I think your idea to have this character mimic only Monster actions is probably the best idea that can be arranged.

Are you wondering what happens to the byte at 33C4 or are you wondering what becomes of the routine it arrived at 33C4 on? If it's the latter it gets overwritten for its original value, has a x2 added to it (to find its proper routine offset) and then it is replace by a 3 which is likely how the game reaches the address 03XXXX for Command Routines.

I thought I would but I now come to the realization that I do not, this is for several reasons now that I think on it. This is never actually related to the routines. You could change the routines to the end of days and you would not see a change in the animation undertaken in said routine.

Now I am intrigued... let me see the reason for that, though I suspect its going to be Index based, depending on command used.

Let's see for sure...

Well that was unfortunate. However there is nothing stopping you from changing the used graphic within the subroutine itself... I think. And it did completely reveal where the Command Subroutines are being held which will be the way to fix "crashes game".

The way it is set up does not leave room for variables, unfortunately. (Command Number + C0 = Graphic shown) With only Magics and Think given special priority because of their variable factors.
