Counter Routine

Code: [Select]
$03/DDC6 AD 9D 26 LDA $269D  [$7E:269D] A:0003 X:0056 Y:0000 P:envMxdizc - Load the Caster's Physical Attack Base into A.
$03/DDC9 AA TAX A:0011 X:0056 Y:0000 P:envMxdizc - Transfer A to X.
$03/DDCA 8E 02 39 STX $3902  [$7E:3902] A:0011 X:0011 Y:0000 P:envMxdizc - Store X in 7E3902.
$03/DDCD 0E 02 39 ASL $3902  [$7E:3902] A:0011 X:0011 Y:0000 P:envMxdizc - Multiply the value by 2.
$03/DDD0 2E 03 39 ROL $3903  [$7E:3903] A:0011 X:0011 Y:0000 P:envMxdizc - Roll the value in 7E3903 by 2.
$03/DDD3 4C AF C9 JMP $C9AF  [$03:C9AF] A:0011 X:0011 Y:0000 P:envMxdiZc - Jump to Damage Determination.
(Seems to somehow leave the routine from here)

Well... that seemed straightforward enough.

This is such a waste of space and opportunity. For whatever reason the game has four extra bytes allocated to it (possibly more) that would easily allow someone to add in an Elemental or Status component.

I will have to move away slightly from my ordinary coding (as shown through Geiger's) to get the point across...

This is what is at 03DDD0 Ordinarily

2E 03 39 4C AF C9 EE 81 38 60 - The 60 is the RTS which takes it out of the routine, but it never seems to be properly read. Nor are the three bytes before it as far as I could tell. It has the barebones basic of being an attack formula without anything added to it.

To...

Say we wanted to add Elemental to this...

2E 03 39 20 30 E1 4C AF C9 60 - This adds in 20 30 E1 Or Jump to E130 which is the Elemental Damage Routine.


Say you wanted Cecil to learn a series of Elemental Sword Attacks, this change would allow the Counter Formula to do so and if you didn't want the data to be the same exact as your physical attack you would change the 7E269D to something else desired. Maybe base it on Cecil's Current MP making it scale in power (and if controlled properly) but shouldn't overtake the power of the available swords. You could also, in essence, cannibalize Sing to give Cid a "Random Element Attack" skill. This is quite a unique formula and it may just be better to expand on it rather than worry about Absorb too much.

 :edit: While the above would work. The bytes following it are Invincibility On for monsters. So it would screw up the Mist Dragon and Zeromus2. There are ways around both of these, of course.

I would wonder, though, if those four bytes are used at an entirely different time.
Once or twice (though I can't remember the specifics), I've seen the game jump to the middle of a subroutine and wondered what instructions were being skipped.
The only way I can think of to test this is to put a breakpoint on 03/DDD6 and play for a while to see if it ever breaks - tedious.

I thought the same thing, but I saw no jump to it in the routine, what it does is Increment the value at 7E3881, which is apparently only used if Monster's are going to become invincible. Well there is the Mist Dragon to test that on...

...And yeah. Bah. It is called for the very specific purpose of turning a Monster invincible and then returning. Why would they put that there rather than place it closer to its own "increment Invincibility Counter" routine? Ah well, I'll have to keep that address jump in mind for when I get to the Increment Invincibility Counter. There has to be a cleaner way to make that work.

$03/DAAD 60 RTS A:0040 X:0081 Y:0028 P:envMxdizc - Return

Now here is something rather interesting! If the Mage Summon is set to Absorb Elemental as well as inflict a status and the enemy happens to Resist Absorb Elemental they will take the damage as a Cure and ignore the Status. Unless they are a Zombie then the damage would be taken as damage. There is a part in the code specifically referring to this behavior for the Absorb Elemental only. If it is just an ordinary Elemental Resistance it is carried out in the Elemental Damage Subroutine. I wonder if they planned for more to the Mage Summon than they ended up including since it is a formula that supports Elemental, Status, and Curing all at the same time.

-------------------------------------------------------------------------------------------------------------------------------
$03/D9F8 60 RTS A:0000 X:00EC Y:0000 P:envMxdiZc - Return

This Routine seems to have a lot in common with the at the start with Damage, Immobilizing Status Routine with the start of it being a copy/paste job it appears, therefore the subroutines and branches covered there will only be marked here without further exploration.

Other than that it is an Extremely thorough formula. With required room for jumps to all of the Status' that can be inflicted without special code. The game never attaches a status to one of these spells and this is a Lot of room that is used by that. So if one wanted to make this into quite a special formula that chance is always before them since the Status portion (the largest chunk of it) is never used normally.

A bit of deja vu... well I guess all of those formula's follow a similar progression so it makes sense that they might somewhat repeat themselves. The definitions of the repeated Jumps are explained in the Mage Subroutine above. No surprises here. While you can change the inflicted status the Timers will likely become askewed because of the absence of Poison.

Where do I even begin...? This is an interesting and unique formula, but it is glitched and the glitch is clear to see if you look at the formula...

Do you see that Adult Rydia check up there? The game never, Ever compensates for slots. It will Only look at Slot 1 and Only if that slot is Adult Rydia will it decrease the proper amount of MP. It is a pretty large oversight and explains why the spell costs no MP. That is unless you have Rydia in Slot 1. Then it will take its proper amount of MP away. This might be able to be fixed by adding a continuous 80 to X as the loops continue.. to have it properly check all five slots. This is such a strange formula, 1 it references Rydia directly which I have seen no other spell formula reference any character directly. 2 it fails in its attempt because it is not very likely that Rydia will be in Slot 1.


Also the SNES version has a catch for Hide as seen above (tested it, it works properly) where as the GBA version does not as DeathLike2 has pointed out before.

Now it makes sense! The reason why Sylph is broken and Odin is not, is because the loop has the 80 attached and it loops immediately to that subroutine, therefore counting all five slots.. As far as I can tell the Sylph formula may have a lot unnecessary fluff that the Odin formula bypasses through a jump rather than having the formula attempt to add 80 itself and fail in the long run. Even so the game doesn't necessarily take Odin's formula into consideration as using Odin as another character will reduce the MP of that character and not just Rydia if Sylph is used. However there is a strange measure that goes along with this where if another character uses Odin, their MP will become Rydia's current MP. But this is only done if Odin fails. If it succeeds nothing special happens with MP.

The Level Checking portion of the spell seems to be located elsewhere. But if the Level Check does not succeed than the game does not even try to load the rest of the routine. Even if you do succeed you have a 50/50 chance of succeeding in using it. That seems a bit low so for balancing purposes it may be best to increase the player's chances a bit to maybe 60-65% chance of success.

Yeah, I always thought of Odin as more of a trophy than a usable spell because of the high failure rate, but I don't think I ever realized it was that high.

Not a very long or complicated code, but this doesn't answer the reasons why the game has trouble killing more than two monsters with Count. Not much help there, I'm afraid.

@Chillfeez - That spell is in desperate need of some help. Unfortunately I can't begin to fathom where this level check is. It may deal something special with simply choosing the spell rather than anything leading up to its casting.


 :edit: 12/26/14 - Well, looks like the answer to Count's Timer was in front of me the whole time. It's just the Spell Power of the given Spell, hence Count's Timer is 0A.

Now this is quite interesting. The player has no access to these so its a moot point really. but if the Target is Weak to whatever Element this could happen to be what it is dividing is the Power. Because I was testing it at 1 originally it turned to 0 making it deal no damage to those weak to it. Heh, that would be a bit of a trap to set the player up for. However if you set it to say... 10, you would ordinarily deal 10% of their HP to the Target. But if the enemy is weak to that element you would be doing 20% of their HP to the target because it is a straight divide. On the flipside if the Target resists the element it will always deal 10% of their maximum HP, regardless of the Spell Power of the Attack. (I forgot how easy it would be to make a Demi spell...)

Hmm, now there are a few interesting items here. One is the Absorb tag when the routine does no damage (normally. If the Absorb routine and is carried through the Target will instead by healed based on the power of the Spell.) and the second is that very familiar sequence at the end which is becoming a staple for Timed Statuses, that is something to take note of. Furthermore I've cast this spell many, many times on enemies and have not frozen the game once, with enemies dying properly. But I can't say the same for the Calcify Weapon Effect. The game will sporadically freeze, as mentioned elsewhere when timers elapse. My thought is that the timer isn't dealt with correctly when the status is inflicted by a weapon. If it's inflicted by a spell it appears to work perfectly fine.

So have no fear in using Calcify as a spell. Just be wary of using it as a Weapon Effect.

------------------------------------------------------------------------------------------------------------------------------------------------

Now here's the first of the random status routines and it is very simple to see how it works. It chooses a random number between 3 and 5 and that random number is how many times a loop will occur making the Status "Of the Spell" go from 00 to 80, from 80 to 40, and since 3 is the first valid choice 40 to 20 which is Paralyze. 4 is 20 to 10 which is Sleep and 5 is 10 to 8 which is Charm in the special branching routine. These are fully malleable and a bit of custom fun could be had with them. That Random Number Generator could be put to great use eventually.

A very short and simple code and as before it is quite malleable. Even moreso in a couple of ways here because this does not use divided numbers but full choices of 20 and 80 and their appropriate routine jumps are shown. It is not shown normally in any circumstance, but the code is redrawn for as many targets as there may be, the afflicted effect may differ from the first time as well.

Now this seems like a nearly ideal way to approach this matter, third time's the charm I guess for Square. They have three options set up that lead to three unique and different occurrences not dependent on any other part (except for Silence using a branch and saving one byte as a result, but other than that...) Now to expand this sort of theory to other parts of the game...

Shortest Code ever?

Well its efficient if nothing else. Even in this form it supplies us with some information. It is clearly just jumping straight to Sap and that should easily be changed to any desired circumstance of like cause.

---------------------------------------------------------------------------------------------

I would have thought it would jump to Cure 4's routine to condense this even further and then jump to Status. Guess I was wrong. It seems to go through the motions of its own accord. Interestingly enough Hug actually obeys the given status for it rather than draw it from anywhere in particular. So say you wanted a powerful status to inflict or something, but you didn't want it viable in the late battle, you could give it Hug's formula to recover all of the enemy's HP when it is used.

I'm a bit confused on this one and I feel that this comparison may not actually be normally fulfilled. I may be missing something really simple in regards to it though.

Because of how the game utlizes this routine it is entirely pointless to be a custom routine in the first place. They could have just as easily make Reaction a Monster Spell which Targets all Allies and apply Death to them. It would not have been a difficult thing to do. If there is any formula that can be devoured and made anew, this is likely it.
