Next up is the Focus/Power/Boost routine. It should seem simple enough in practice.

Code: [Select]
$03/E7F0 EE 0A 39 INC $390A  [$7E:390A] A:0003 X:001A Y:0000 P:envMxdizc - +1 to 7E390A.
$03/E7F3 A9 1F LDA #$1F A:0003 X:001A Y:0000 P:envMxdizc - Load 1F into A.
$03/E7F5 8D 7B 39 STA $397B  [$7E:397B] A:001F X:001A Y:0000 P:envMxdizc - Store A in 7E397B.
$03/E7F8 A9 0C LDA #$0C A:001F X:001A Y:0000 P:envMxdizc - Load 0C into A.
$03/E7FA 85 D6 STA $D6    [$00:00D6] A:000C X:001A Y:0000 P:envMxdizc  - Store A in D6.
$03/E7FC A5 CD LDA $CD    [$00:00CD] A:000C X:001A Y:0000 P:envMxdizc - Load Character Identifier Into A.
$03/E7FE 20 36 9E JSR $9E36  [$03:9E36] A:0000 X:001A Y:0000 P:envMxdiZc - Jump to Subroutine (Likely something dealing with Timers and Speed.)
$03/E801 A9 03 LDA #$03 A:0000 X:0005 Y:0005 P:envMxdizc - Load 03 into A.
$03/E803 20 C8 85 JSR $85C8  [$03:85C8] A:0003 X:0005 Y:0005 P:envMxdizc - Jump to Subroutine (Difficult to Say)
$03/E806 A9 08 LDA #$08 A:0000 X:0003 Y:0005 P:envMxdiZc - Load 08 into A.
$03/E808 9D 06 2A STA $2A06,x[$7E:2A09] A:0008 X:0003 Y:0005 P:envMxdizc - Store A in 7E2A09.
$03/E80B A6 A6 LDX $A6    [$00:00A6] A:0008 X:0003 Y:0005 P:envMxdizc - Load X from A6 (Character Slot)
$03/E80D BD 05 20 LDA $2005,x[$7E:2005] A:0008 X:0000 Y:0005 P:envMxdiZc - Load Slot X's Status Byte 3.
$03/E810 09 08 ORA #$08 A:0000 X:0000 Y:0005 P:envMxdiZc - Add 08 if not already there (Charging)
$03/E812 9D 05 20 STA $2005,x[$7E:2005] A:0008 X:0000 Y:0005 P:envMxdizc - Store Charging in Slot X's Status Byte 3.
$03/E815 A9 1F LDA #$1F A:0008 X:0000 Y:0005 P:envMxdizc - Load 1F into A. (Action to take after the timer has expired.)
$03/E817 9D 51 20 STA $2051,x[$7E:2051] A:001F X:0000 Y:0005 P:envMxdizc - Store 1F in Slot X's Next Action to Take.
$03/E81A 20 A6 85 JSR $85A6  [$03:85A6] A:001F X:0000 Y:0005 P:envMxdizc - Jump to Subroutine (??)
$03/E81D A9 39 LDA #$39 A:0003 X:0000 Y:0005 P:envMxdizc - Load 39 into A (D)
$03/E81F 8D CA 34 STA $34CA  [$7E:34CA] A:0039 X:0000 Y:0005 P:envMxdizc - Store A in Battle Message Data.
$03/E822 60 RTS A:0039 X:0000 Y:0005 P:envMxdizc - Return

Only the basics of what you would expect are in here, but most interestingly is $03/E817   9D 51 20   STA $2051,x[$7E:2051]   A:001F   X:0000   Y:0005   P:envMxdizc - Store 1F in Slot X's Next Action to Take..

What this does is it would allow you to set the next action you take. what takes away the Charging Status is held in Command 1F. You could set it to a normal command of any sort (as long as it doesn't open a sub-menu) and you would effectively have a permanent Charge status, meaning you would deal double the damage, but you would also still be heavily afflicted by Charging's detriments.

The second part of Focus as you would imagine is the actual attack.

Focus (Command 1F) Routine -

Code: [Select]
$03/E823 20 99 C4 JSR $C499  [$03:C499] A:0003 X:003E Y:0000 P:envMxdizc - Jump to Subroutine (All of the Fight Routine)
$03/E826 A5 CD LDA $CD    [$00:00CD] A:0000 X:750E Y:0018 P:envMxdiZC - Load Character Identifier into A.
$03/E828 20 89 84 JSR $8489  [$03:8489] A:0000 X:750E Y:0018 P:envMxdiZC - Jump to Subroutine (Preparation?)
$03/E82B A6 A6 LDX $A6    [$00:00A6] A:0000 X:0000 Y:0018 P:envMxdiZc - Load Character Slot into X.
$03/E82D BD 05 20 LDA $2005,x[$7E:2005] A:0000 X:0000 Y:0018 P:envMxdiZc - Load Slot X's Status Byte 3 into A.
$03/E830 29 F7 AND #$F7 A:0008 X:0000 Y:0018 P:envMxdizc - -8, getting rid of Charging Status.
$03/E832 9D 05 20 STA $2005,x[$7E:2005] A:0000 X:0000 Y:0018 P:envMxdiZc - Store A in 7E2005.
$03/E835 60 RTS A:0000 X:0000 Y:0018 P:envMxdiZc - Return.

And that is it for Focus. Maybe with a bit more wit we could refocus the JSR to not look at Fight, but then where would an applicable place be?

Next up is Aim another self-explanatory command.

Code: [Select]
$03/E836 AD 9C 26 LDA $269C  [$7E:269C] A:0003 X:0018 Y:0000 P:envMxdizc - Load Caster's Physical Attack Percent.

$03/E83D 48 PHA A:0000 X:0018 Y:0000 P:envMxdiZc - Push A.
$03/E83E 7B TDC A:0000 X:0018 Y:0000 P:envMxdiZc - Transfer Direct Page (thereby making it 00)
$03/E83F 8D 29 27 STA $2729  [$7E:2729] A:0000 X:0018 Y:0000 P:envMxdiZc - Store 00 in Target's Evasion.
$03/E842 3A DEC A A:0000 X:0018 Y:0000 P:envMxdiZc -1 to A.
$03/E843 8D 9C 26 STA $269C  [$7E:269C] A:00FF X:0018 Y:0000 P:eNvMxdizc - Store A  (FF - 255%) into Physical Attack Percent.
$03/E846 20 99 C4 JSR $C499  [$03:C499] A:00FF X:0018 Y:0000 P:eNvMxdizc - Jump to Subroutine (Full Fight Routine)
$03/E849 68 PLA A:0000 X:750E Y:0018 P:envMxdiZC - Pull A.
$03/E84A 8D 29 27 STA $2729  [$7E:2729] A:0000 X:750E Y:0018 P:envMxdiZC - Store A in Target's Evasion.
$03/E84D 68 PLA A:0000 X:750E Y:0018 P:envMxdiZC - Pull A.
$03/E84E 8D 9C 26 STA $269C  [$7E:269C] A:0034 X:750E Y:0018 P:envMxdizC - Store A in Caster's Accuracy.
$03/E851 60 RTS A:0034 X:750E Y:0018 P:envMxdizC - Return

It seems like only yesterday that I was flummoxed about how to make Aim into a less absolute command. At the time I knew very little and thought it was hopeless, but now I see what Square meant to do and because of what we have a bit freer space. Evasion would only ever effect battles against Valvalis/Barbariccia in the normal game. Therefore I think we could take those Evasion references and make them into something else.

I decided for this experiment to make the Accuracy of the currently equipped Bow to become the new Critical Hit Chance and x2 Accuracy.


$03/E836   AD 9C 26   LDA $269C  [$7E:269C]   A:0003   X:0018   Y:0000   P:envMxdizc - Load Caster's Accuracy.

$03/E851   60    RTS   A:0034   X:2306   Y:0018   P:envMxdizC - Return.


It took a little bit of time to figure it out, to make all of this work but it is tried and tested and works flawlessly. It gives Aim that extra push it needs to stack up against the better Commands and it only gets better as the game goes on, with the last bow the player will likely get topping out at 60% Critical Hit Chance for each attack whenever they use Aim with the Samurai Bow. Perhaps its a bit broken, but I was working with a bit of limited space after all, hehe.

 :edit: January 5th 2014 - 2 New Aim Replacements!

Wow... Barrage (FFIII DS, FFT:War of the Lions) was a Stupidly easy thing to program in the end... at least in a basic form...

Because of space limitations I decided to call it (Arrow Symbol)Strm (Arrow Storm) after a tactic common to the Romance of the Three Kingdoms series.

Code: [Select]
$03/E836 20 99 C4 JSR $C499  [$03:C499] A:0003 X:0018 Y:0000 P:envMxdizc - Fight Routine x4
$03/E839 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E83C 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E83F 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E842 60 RTS A:0000 X:750E Y:0018 P:envMxdiZC - Return
Yes, four normal attacks. I honestly thought this was going to cause an overflow problem with the arrows, but to my amazement the game Properly decrements them without overflowing. (And if used with less than 3 Arrows you will no longer have any arrows) And as you'd expect it deals x4 Damage (though without my Infinite Arrow-Glitch fix it still has that problem as you'd expect.)


Now, these all add up properly, but there's still two pieces I'm missing. This first is how to divide the damage by 2. I may need to look back at the original Aim Command for guidance... Specifically at...

$03/E836   AD 9C 26   LDA $269C  [$7E:269C]   A:0003   X:0018   Y:0000   P:envMxdizc - Load Caster's Physical Attack Percent.
$03/E839   48    PHA   A:0034   X:0018   Y:0000   P:envMxdizc - Push A.

That seems like a fine start to a recipe actually.

Well... I learned something through this experience... Never Ever Forget to Retrieve Your Pushed Values!!

For roughly an hour I was looking at my preliminary code, wondering what I was doing wrong, when it finally dawned on me that because I was testing the pure functionality I never retrieved the Pushed value back and this causes a system crash.

So I now have Arrowstorm working like Barrage from FFT:War of the Lions! 4 half-damage attack that takes 4 Ammo for roughly 2x damage (but it attacks four times so even more chance of a status infliction if applicable)

Arrowstorm

Code: [Select]
$03/E836 AD 9D 26 LDA $269D  [$7E:269D] A:0003 X:0018 Y:0000 P:envMxdizc - Load Caster's Physical Attack Base.
$03/E839 48 PHA A:0053 X:0018 Y:0000 P:envMxdizc - Push A onto Stack.
$03/E83A 4A LSR A A:0053 X:0018 Y:0000 P:envMxdizc - Divide Physical Attack Base by 2.
$03/E83B 8D 9D 26 STA $269D  [$7E:269D] A:0029 X:0018 Y:0000 P:envMxdizC - Store A in Physical Attack Base.
$03/E83E 20 99 C4 JSR $C499  [$03:C499] A:0029 X:0018 Y:0000 P:envMxdizC - Fight Routine x 4
$03/E841 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E844 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E847 20 99 C4 JSR $C499  [$03:C499] A:0000 X:750E Y:0018 P:envMxdiZC
$03/E84A 68 PLA A:0000 X:750E Y:0018 P:envMxdiZC - Pull A
$03/E84B 8D 9D 26 STA $269D  [$7E:269D] A:0053 X:750E Y:0018 P:envMxdizC - Store A in Physical Attack Base (original value)
$03/E84E 60 RTS A:0053 X:750E Y:0018 P:envMxdizC - Return

Now, FFIII's Barrage is a little trickier to get down...

The way that works is each shot deals full damage +another 10-40% depending on the Job Level. To mimic this, (as well as I can...) I would instead make it look at Strength. At
0-39 Str. There would be no bonus. 40-60 1/8 Bonus in Damage, 60-99 1/4 Bonus in damage. It might encourage people to use Rosa in a Strength set-up rather than always going for the Will set-up possibly. But this seems like it will take a bit more space than Aim actually supports. So I'll have to hold off on that for now.

Though I suppose I could make a variant... (looks back at how he programmed Aura originally...) Yes. Instead make it so that Two Attacks will occur automatically. And if you have over 45 Strength a third one happens and at over 60 strength a fourth one occurs.

Barrage (Arrowstorm) FFIII "Style" (Sort of)

Geez, I must really love the Aim Command, I've now made three variants for it!

Next up is Pray, just like with Gird, I don't expect to find many surprises and it is a fairly short command by all accounts.

Pray Routine -

Code: [Select]
$03/E852 20 93 85 JSR $8593  [$03:8593] A:0003 X:0016 Y:0000 P:envMxdizc - Jump to Subroutine (Generate Random Number)

$03/E875 60 RTS A:0010 X:00CE Y:0000 P:envMxdizC -Return

Quite short and quite simple. It's becoming alarmingly clear. It seems all you need to do to get a command to use a Spell is...


$03/E863   A9 0E   LDA #$0E   A:001C   X:0083   Y:0000   P:eNvMxdizc - Load Spell into A.
$03/E865   8D D2 26   STA $26D2  [$7E:26D2]   A:000E   X:0083   Y:0000   P:envMxdizc - Store A in Next Action to take.
$03/E868   20 3E CD   JSR $CD3E  [$03:CD3E]   A:000E   X:0083   Y:0000   P:envMxdizc - Jump to Subroutine (Magic Call)

And that's it. Gird and Pray tell the same story in this regard. Making the "break the game" Command into an Actual skill for Cid (by using the saved bytes from their copied Peep info) is becoming more and more like a simple reality.

Next is Hide, let's see what that can tell us...

$03/E8BA 60 RTS A:0010 X:7504 Y:000A P:envMxdizC - Return

Now this is the first command that I've actively noticed this (and is likely true to Cover and Off as well) but the forced changing of the command is purely dealt with by using the Hide command. Now this has very interesting possibilities... Due to the way the game works, changing Commands that are on a character with the normal tools available to do so are only done normally through Different References of the same character outside of battle and Commands in-battle. What this seems to show is that we can change commands with a little bit of custom code at any time we please. Say we make an item that utilizes Dispel's formula space that gives a character a new skill. For instance, giving Paladin Cecil back Dark Wave through a custom event that rewards a special item that could only be used by Cecil (Proof of Concept in Crystal) which would move Item to Slot 5 and add Dark Wave to Slot 4.

Next up is Show.

Some interesting information gleaned from this. Something that is not seen in other commands and wholly unique to Hide is the inability to use any Command but Show afterwards. What is clear now is that the reference to 3302 (first byte of commands) is that it governs whether it can or can't be used. You can use no Commands under hide because the only exception made in it is for Show. All the others had have 80 added to their base value.

Let's finish this batch of information up with Sing. I don't expect to find much here, likely the percentage chance of each Song to occur and perhaps even find Frog Song.

Indeed, now this is a Command! Four random options, one easily located reasoning for how things work as they do, and a bonus of Status specialty. Which one can easily change and make look for anything they desire to make it play the special circumstance song. And plainly listed above are the chances for each song to change if they would like.

But that will do it for tonight, only a couple standard Commands left to go!

Jump is the next object of interest I don't expect to see much different from the other "apply status to self" commands, but we'll see.

Quite a few "Enemy Kain Only" branches to be found within the routine, likely targeting and special circumstance. Still not sure why it doesn't use 1E like the normal Jump does or what is even different about DE.


It seems like the only purpose of the branches for Enemy Kain are to allow the Jump attack to actually go through, which is a strange thing to limit in the first place. Why shouldn't Kain be allowed to target Allies? It would free up a bit of space in the routine as well for anything a hacker would like to add.

Now, let's revisit one of the first commands I looked at and see if I can completely decipher it now...

Well that was quite a bit simpler this time around, everything was easily deciphered.

First, I've decided to make Dark Wave's death penalty more substantial...


$03/EA04   A9 00 00   LDA #$0000   A:FFF8   X:0000   Y:0000   P:eNvmxdizc - Load 0000 into A.
$03/EA07   9D 07 20   STA $2007,x[$7E:2007]   A:0000   X:0000   Y:0000   P:envmxdiZc - Store A in User's HP.
$03/EA0A   A9 80 00   LDA #$0080   A:0000   X:0000   Y:0000   P:envmxdiZc - Load 0080 into A.
$03/EA0D   9D 40 20   STA $2040,x[$7E:2040]   A:0080   X:0000   Y:0000   P:envmxdizc - Store A in User's Creature Type (Undead)


I'm going to go out on a limb and say this is what it May have originally been, or at least planned. Because setting the HP to 0 automatically will kill the user regardless, making the Death Application superfluous. This will prevent the player from being able to revive Cecil if he killed himself with Dark Wave, as it applied the Undead-type to him.

Furthermore the jump to Kick is basically reading the entirely of the Kick Routine, meaning that you could Easily set it to the Fight Routine and have Dark Wave hit only a single target, now unfortunately, it would then only act like a normal attack without modifying the Fight Routine or Dark Wave Routine itself to compensate the new addition to it.

For instance, say you want to make Dark Wave more like Darkness in FFIV:DS, an attack that hits one enemy for Double Damage, but takes HP.

You would change...

$03/EA10   7B    TDC   A:0013   X:0000   Y:0000   P:envmxdizC - Transfer Direct Page
$03/EA11   E2 20   SEP #$20   A:0000   X:0000   Y:0000   P:envmxdiZC - Set Processor Status.
$03/EA13   A9 01   LDA #$01   A:0000   X:0000   Y:0000   P:envMxdiZC - Load 01 into A.

$03/EA17   4C B9 E6   JMP $E6B9  [$03:E6B9]   A:0001   X:0000   Y:0000   P:envMxdizC - Jump to Routine (Most of Kick Routine)

To this...

$03/EA10   E2 20   SEP #$20   A:0039   X:0000   Y:0000   P:envmxdizC - Set Processor Status (in order to have it read only one byte rather than two)
$03/EA12   A9 04   LDA #$04   A:0039   X:0000   Y:0000   P:envMxdizC - Load 04 into A. (x2 Power)
$03/EA14   8D FE 38   STA $38FE  [$7E:38FE]   A:0004   X:0000   Y:0000   P:envMxdizC - Store A in Damage Altering Field.

As long as the enemy itself has no weakness or resistance to the Elemental or Creature Type Attack, then Dark Wave will carry through as a normal attack at x2 Damage. Otherwise those variables will nullify it and replace it with an ordinary one.

Or if you want to make Dark Wave cast a Spell at 1/8th of your HP you would instead...

$03/EA10   E2 20   SEP #$20   A:0039   X:0000   Y:0000   P:envmxdizC - Set Processor Status (in order to have it read only one byte rather than two)
$03/EA12   A9 A2   LDA #$A2   A:0039   X:0000   Y:0000   P:envMxdizC - Load A2 into A. (Emission)
$03/EA14   8D D2 26   STA $26D2  [$7E:26D2]   A:00A2   X:0000   Y:0000   P:envMxdizC - Store A in Next Action to take.
$03/EA17   4C 3E CD   JMP $CD3E  [$03:CD3E]   A:00A2   X:0000   Y:0000   P:envMxdizC - Jump to Spell Routine.

But it is not that simple. The Magic Call seems to put the Caster stats above all else and will put that in initial stats at the end of the routine, meaning that if you want Dark Wave to cast a spell that hurts Cecil 1/8 HP you would also bear this in mind and change an earlier part of the routine...

Change this...

$03/E9FA   BD 07 20   LDA $2007,x[$7E:2007]   A:0019   X:0000   Y:0000   P:envmxdizC - Load User's Current HP.

To this...

$03/E9FA   BD 87 26   LDA $2687,x[$7E:2687]   A:0019   X:0000   Y:0000   P:envmxdizC - Load Caster's Current HP.

And there you have it. Two different ways to modify Dark Wave, one is to simulate Darkness from FFIV:DS and the other is to allow it to cast a spell, if one actually wanted to use something more complex than Kick's routine or normal attack modification.

Next up is a personal favorite of mine, and a very important command for documenting purposes, and that is Recall. It is the only command aside from Twin which uses MP to cast its magics and fails if the MP is not enough.

Recall Routine -

Well that was as expected. Except I expected MP to be in here, but I think I see what's going on... what is unique about Recall that is not in the other Commands is that it starts At The Start of the Magic Call routine. Unlike Pray and Gird, MP Cost is likely a part of the near-beginning of the Magic Call Routine.

And... that's not the reason why. The real reason it takes MP into account is because 7E355D.

To this...

We are at the home stretch now! All that remains are Boast/Bluff, Cry, and Item and that will be it for conventional commands.

Boast Routine -

That was simple. I've written instructions on how to have the routine read and increase any stat the player may please, but it should be very obvious by just looking at the commented data above.

Next up is Cry, that I've already discussed at some length elsewhere. I don't expect to find much here.

Oh? So it seems as if it was not supposed to be a static value, but by the way the game works "Steal Prevention" never goes up for Porom and is always at a static 0A /2 = 5. Because it reads Monster Slots rather than any real kind of targeting, changing targeting could be difficult.

There is a part of code that Phoenix could never decipher which he just labelled "Item/Dart Check?" That I cannot figure how to access. I could not get it to activate with either Dart or Item checks, using any kind of item I couldn't get it to activate, hmm...

Last in conventional commands is Items then...

Secondly is how the game draws the summons in the first place and how they are specialized.

If you change the E5 as listed above to 00 you can use the Grimoire to use any spell and combination thereof of to spells that you would like it to use. The purpose of the negative values is for spells that only hit one enemy (Chocobo, Sylph) and the negative part allows it to go through a special part of the routine where its targeting becomes randomized, neatly enough.

The one thing I could not figure out is how the Grimoire's damage is calculated. Their default power according to the item is 00. Maybe it's something I missed in the routine.

That does it for the moment, I still need to post a full look at the Magic Call routine, but I think we're at the home stretch.

Note:
Another mystery solved!

Code for Command Starting Graphics...
Code: [Select]
00-BF - Assigned by Spell.

C0 - Weapon Swing
C1 - None
C2 - White Magic
C3 - Black Magic
C4 - Summon Magic (Also includes the party vanishing)
C5 - Dark Wave
C6 - Character Jumps into the Air
C7 - Character does their Special Pose. (Recall)
C8 - Spell Pose is Held as White Magic light shows (Sing)
C9 - Run from battle (Hide)
CA - Just normal Spell/Item Use pose. (Salve)
CB - Pray
CC - Special Pose - Weapon Attack (Aim)
CD - Spell Pose is Held while attack happens (Focus)
CE - Kick
CF - Gird
D0 - Twincasting
D1 - Boast
D2 - Cry
D3 - Cover
D4 - Peep
D5 - Crash (Just a normal spell casting pose)
D6 - Dart (When used outside of its normal routine, shows a hand stuck in the foe as used in Fight without a weapon)
D7 - Sneak
D8 - Ninja
D9 - Regen
DA - Change
DB - Parry
DC - Character runs all the way from one side of the screen to the other, back to the front. ??
DD - Normal Spell Casting Pose.
DE - Return from Jump
DF - Second part of Focus (Attack)


I am still not finished, there's still a bit more to find and a lot of this is copy-pasted from my Salve Routine. I am not sure how MP is handled or Accuracy, or how Items with magic attached to them is calculated. As what makes the special magic graphics appear, that I have found and can go back through my earlier routine searches and point them out now that I know what they are.

Re: Grimoire LD's Notes, Methods, and Hacks (All Spells Disassembly)

 I've found the Magic Weapons section! It is very small and all of the information I had hoped to find was plainly there. (For full information refer to the Item Routine post as that is where it is stored)

So now open to us is the ability to decide what powers the Weapon Spell. Default it is Magic Power (Weapon) + Spell Power of Spell.

$03/EBDE   BF 70 90 0F   LDA $0F9070,x[$0F:9077]   A:0007   X:0007   Y:0000   P:envMxdizc - Load A from 0F9070+X. (Spell's Power as designated by weapon)
$03/EBE2   8D EC 38   STA $38EC  [$7E:38EC]   A:0001   X:0007   Y:0000   P:envMxdizc - Store A in 7E38EC. - Store A in Spell Power.

To those who were never comfortable with this you can change or null both of these values (with EA's) to have the weapon use the ordinary magic routines, using Wisdom or Will dependent on the spell's location on the list.

Though more importantly is the Accuracy Exception. This took a bit of time to track down, and I imagine its likely in other attack Commands as well.
$03/EBE5   EE EB 38   INC $38EB  [$7E:38EB]   A:0001   X:0007   Y:0000   P:envMxdizc - +1 to 7E38EB. - +1 to Ignore Accuracy. (Thereby ignoring the accuracy of the weapon spell)

From preliminary testing it seems that it works for any action taken. Fighting or otherwise. Now I have to wonder why they didn't just use that for Aim rather than a rather clumsy way of making the value FF?

That said, I'm not sure how the Slumber Blade worked previously... it is the only Weapon Spell Effect that did not seem 100%, but clearly the Ignore Accuracy byte was enabled normally. I think the team must not have been aware of this byte, as the Weapon Spells clearly were not meant to be 100% seeing as they have Accuracy that are in all different amounts.

Now I wonder how difficult it would be to make the Fight Routine read the Weapon Spells and cast them on a random basis...

I was just thinking about that the other day. You'd definitely have to write some custom code... I guess it would look like (in english):
Check if spell is assigned
If not, return
Generate random #
Check if # is (in desired range)
If not, return
Check/store assigned spell
Jump to magic routine

... something like that?

It seems so simple in theory. I've already seen that the game is capable of showing one effect, then another, whether that effect be Dark Wave which transitions into a different graphic or what have you.

What you have there seems perfect for that idea.

Check if spell is assigned
B1 80   LDA ($80),y[$7E:32E9]   A:0001   X:0007   Y:0003   P:envMxdizc - Load A from Character's Hand Data - Spell

If not, return
BEQ XX - Branch if 00 to elsewhere.       

Generate random #
20 93 85   JSR $8593  [$03:8593]   A:0000   X:0010   Y:0000   P:envMxdiZc - Jump to Subroutine (Generate Random Number.
Check if # is (in desired range)
CMP 34 - Did it land below 34?
If not, return
BNE XX - If not, branch to elsewhere.
Check/store assigned spell
B1 80   LDA ($80),y[$7E:32E9]   A:0001   X:0007   Y:0003   P:envMxdizc - Load A from Character's Hand Data - Spell

Jump to magic routine
20 3E CD   JSR $CD3E  [$03:CD3E]   A:0029   X:0054   Y:0000   P:envMxdizc - Jump to Subroutine (Magic Call)

In theory it looks so simple. But the only problem would be, is the Spell over-riding the Normal Attack then? Only trouble is where could this be put and drawn from? When should it occur in the routine and most importantly and what will it be replacing in the routine itself?

Ideally, I guess the player would want the spell to occur in addition to the attack damage. I mean, if I just want to cast the spell, I'll just use the weapon as an item. But I sincerely doubt that the game is capable of doing that - there is no other instance of a single character attack that generates multiple damage calls.
You could (I think):
  • Store zero in 00A2-00A3 (end damage result location)
  • Check for weapon spell
  • If none, jump down to regular attack routine
  • RNG
  • Check if random number is within range
  • If not, jump to regular attack routine
  • Load weapon spell
  • Jump to spell subroutine (which will return here when finished)
  • Regular attack routine
  • Add attack result to 00A2-00A3

In theory, I think this would cast the spell (if luck deems it so), then attack, and combine the resultant damage. Setting A2-A3 to zero first would ensure that if no spell is cast, only the attack's damage would be applied (instead of, say, being added to residual values from whatever the last attack was).

That is quite the theory. I can see no problem with it, only I find it a bit difficult to work through in our current Attack and Magic routines. Using Peep and turning it into a composite command (maybe a "Fight" command especially for Mages only, that have a chance to use these Weapon Spells when they attack.)

This would ideally be stacked with a "Weapon Charge" or "Weapon Decrement" hack, so as to make the choice a bit more tempting. I can see utilizing the Fight Command to full, and then something that loads the spell into the next action to take... it is quite a difficult theory to utilize, at least with thoughts of success.

Here Square, let me help you out a little with this...

Code: [Select]
$03/E153 A9 0D LDA #$0D A:0003 X:0028 Y:0000 P:envMxdizc - Load Peep into A.
$03/E155 8D D2 26 STA $26D2  [$7E:26D2] A:000D X:0028 Y:0000 P:envMxdizc  - Store A in Next Action to Take
$03/E158 9C C4 33 STZ $33C4  [$7E:33C4] A:000D X:0028 Y:0000 P:envMxdizc - Store Zero in 7E33C4.
$03/E15B 4C 3E CD JMP $CD3E  [$03:CD3E] A:000D X:0028 Y:0000 P:envMxdizc - Jump to Magic Call.

And Done!

That accomplishes the Peep Command in only 12 Bytes. When the normal command is...

94 Bytes. That frees up 82 Bytes for "Airship" Or whatever the "crash the game" skill was supposed to be. Or should it be a Mechanize skill that looks for the Third Weapon Property to work? (As all Hammers have) That will transform the Foe into a Machine? Or maybe he should get a variation on his FFIV DS skill that would turn his weapon into an Elemental, using the system laid down by Salve that looks for the first reference to an Elemental-Damage Item, and stores that in Cid's Elemental Attack.

And if we do go the Airship Route, what would it exactly do? From the sound of things it may have been intended to be an Airstrike of some sort. (After all Cid did say he had the Enterprise on Remote Control) Non-Elemental Damage on all enemies using Strength as a base, maybe? The possibilities in this regard are literally endless. (Or within 82 Bytes worth)

So please, feel free to give your own thoughts on what should be done with the freed up space left by Peep?
