Whew! A lot of coding there, but worth it in some respects, the way the game draws spells can easily be discerned, but I somewhat doubt this set is used for monsters at all.

Well, that was interesting. I found what I was looking for and here is the useful information to the casual hacker who may not want to pore through code to find inexact numbers.
...
And there you have it! All of the Status Timers to see where these are in ROM just add 1FE00 to these values. (Remember, non-headered ROM)
 :edit:
Heh, well Count's Timer is silly simple. It's the Spell Power of any spell that casts Count. All things with Count are mostly drawn from my initial Routine recording.

Pointers to Status Expirations

Located at 038922

Status Expirations

03A897 - Stop Timer
03A8CC - Hold/Sleep Timer
03A8E6 - HP Leak
03A8FD - Poison
03A978 - Gradual Petrification
03A9D8 - Wall
03A9EF  - Count


That is so cool!  :cycle:  It's the little the little things like that (regardless of whether or not they actually work) that always keep me coming back. It's what made me a scientist too. But truly; as always, excellent work my friend.  :cookie:

Quote from: Grimoire LD on December 25, 2014, 06:15:37 PM
Far too long if you ask me, yes I noticed this as well that the game's battle system is generally slow, I even removed the "Damaged from Poison" text box because it is generally clear why something is taking the damage that they're taking. I do wonder if they made an error with HP Leak though, wearing off after 40 ticks of 1 HP seems ill-made, I imagine it was meant to go for a lot longer or deal a lot more damage at one point in time. But as far as I'm aware no remake has bothered to make it do more than that.

I was actually screwing around late last night, thinking about this topic specifically: Would it be possible to cause Zeromus to die from HP Leak when he is in the last phase of his battle script and sitting there casting Meteo over and over. I remember discovering on this forum (I think) that negating status effects was built into his routine - but I wasn't sure if that carried into the final phase where he is no longer scripted to shake. I'll poke around more into that but these kinds of things pique my curiosity and it's always neat to see the gears that make the works.  -- It was also for my own more personal interests a bit of a math puzzle - I was trying in the end to balance out damage done by Palom's Virus amount restored by Porom's Cure 2/3 and then (save-state / rewind ) - repeat. It was an amusing way to kill a spot of time  :tongue:  Note: For extra fun notice the slightly non-standard party  :wink:

Thanks!  My purposes were just to figure out the fundamentals of the ATB system, including how long between each turn and how long each status timer typically lasts.  I hadn't come across discussion that quite satisfied my need for something more formulaic.  The most interesting thing to me is that the ATB ticks are paused almost all the time.  Any time a character or monster is performing an action, showing a spell animation, showing a message on the top of the screen, the timers all wait.  This can be witnessed with a very short casting period for a spell when nothing else is happening vs a very long casting period if any other players or monsters are "doing" something.


Agreed! ATB in FF IV is very "except after 'C'." I would love to have formulas that you could easily follow the changes in - but that's my answer to everything.  :wink:   One thing that interests me is that I know that there are problems (at least in some versions) with Stop - some pretty severe...I'm curious as to where the game actually fails.  :hmm:  BTW - Welcome to the Forum, avalanche!  :happy: that notes you posted on ATB seemed pretty interesting: keep up the good work!  :childish:

Interesting experiment, I would see no reason why you couldn't kill Zeromus with HP Leak, he is just another enemy. The only thing I'd wonder is if the line "HP Ran out" would show up. You didn't quite write if the experiment worked or not. I imagine it would have, but you can never be too sure with FFIV.

That is a good question on why Stop breaks the game in several ways in the SNES versions, my guess is something about timers not clearing correctly, hence the entire battle system grinds to a halt. In theory all of the information to figure that out is now available. I would also love to know what goes wrong with Count. Death Sentence is such a neat idea for a status and would make an ideal replacement to any "instant-ko" weapon, but Count doesn't work properly on enemies for some reason...

Weirdest part about count is that it works fine on the first monster it's used on each battle, but doesn't work at all after that. I believe, too, that if the effects are split, it doesn't work on any of the monsters (I might be wrong about that - it was a while ago that I played around with it).

Oh no, if you try to use Count on all or split-all monsters, the game locks up when the timers reach 00, seemingly unable to figure out what to do next. I think Count can take out the first two enemies (as seen with the plague enemies), but it cannot take out the last one at all. It is rather strange and my bet is some built-in safeguards against it which actually end up making things worse, but without seeing the routine it's difficult to say.

You didn't quite write if the experiment worked or not. I imagine it would have, but you can never be too sure with FFIV.

I didn't say because the vote wasn't in yet - though at the very least I could have said that  :tongue:  I was trying to batt Zeromus' HP around - without watching the RAM (I was in ZSNES at the time) - but eventually I fell asleep. But I saddled up for another round in good ol' 9X and - yep! You see no reason it shouldn't work because there is no reason it wouldn't work: it did work!! :laugh:

Does anyone have a line on how accurate or recent this list is:     http://datacrystal.romhacking.net/wiki/Final_Fantasy_IV:RAM_map

I will say that:   "7E2307-8 - Enemy's current HP - Slot 01"    is spot on even for US_IIv1.1 - That's what I ended up exploiting to finish him off: Cast Virus, made sure the leak was is full effect, paused and took his HP down to 5 (see how he likes it!) and then when I called 'time-in' - that was pretty much that.  :wink:

 :hmm:  -- Very strange about count. I've seen a lot of speed runs where through various methods they manage to get "Reaction" as spell that that FuSoYa can cast - labeled "upt Co" from falling between Disrupt and ColdMist. Anyway...the reason I bring that up is I've heard Reaction explained as a change of state: straight Living --> Dead...rather than inflicting death. I was wondering if Count worked the same way. Also, looking in Pink's editor it looks like the "Reaction" Spell is entry 173 in the spell list marked Dummy - with and effect of: "Suicide, bring in next monster" - hmmm

Interesting experiment, I would see no reason why you couldn't kill Zeromus with HP Leak, he is just another enemy. The only thing I'd wonder is if the line "HP Ran out" would show up. You didn't quite write if the experiment worked or not. I imagine it would have, but you can never be too sure with FFIV.

I didn't say because the vote wasn't in yet - though at the very least I could have said that  :tongue:  I was trying to batt Zeromus' HP around - without watching the RAM (I was in ZSNES at the time) - but eventually I fell asleep. But I saddled up for another round in good ol' 9X and - yep! You see no reason it shouldn't work because there is no reason it wouldn't work: it did work!! :laugh:

Does anyone have a line on how accurate or recent this list is:     http://datacrystal.romhacking.net/wiki/Final_Fantasy_IV:RAM_map

I will say that:   "7E2307-8 - Enemy's current HP - Slot 01"    is spot on even for US_IIv1.1 - That's what I ended up exploiting to finish him off: Cast Virus, made sure the leak was is full effect, paused and took his HP down to 5 (see how he likes it!) and then when I called 'time-in' - that was pretty much that.  :wink:

 :hmm:  -- Very strange about count.

Reaction is indeed a change of state, you can see this here...

http://slickproductions.org/forum/index.php?topic=1883.msg19250#msg19250

Load Death into All enemy's status bytes. No checks, no nothing. Count is the same way since even if you are protected from Death you will still be killed by Count.

Surprisingly, this can be fixed very easily...

$03/A9F8   BD 06 20   LDA $2006,x[$7E:2012]   A:0003   X:000C   Y:000D   P:envMxdizc - Load Status Byte 04 into A.
$03/A9FB   30 11   BMI $11    [$AA0E]   A:0003   X:000C   Y:000D   P:envMxdizc - Branch if Hiding to Return.
$03/A9FD   A6 A6   LDX $A6    [$00:00A6]   A:0003   X:000C   Y:000D   P:envMxdizc - Load Target Identifier (But you just did that!)
$03/A9FF   BD 03 20   LDA $2003,x[$7E:200F]   A:0003   X:000C   Y:000D   P:envMxdizc - Load Status Byte 01 into A.
$03/AA02   09 80   ORA #$80   A:0003   X:000C   Y:000D   P:envMxdizc - Add 80 (Death) if applicable.
$03/AA04   9D 03 20   STA $2003,x[$7E:200F]   A:0003   X:000C   Y:000D   P:envMxdizc - Store A in Status Byte 01

This does show that they intended to have Edward come back to the party, but it's never utilized in the original FFIV,  you can switch that to look at the Status Resistance Byte which is literally the same value in this case as Hide (80) and you could fix it like that. I don't think that will solve the issue... but you may be onto something... if instead of going through with the original routine, I wonder if linking it to the basic "Status Routine" might fix these weird timer problems, I will have to try that soon, thanks for the idea LordGarmonde.

You are under one misinterpretation though. Reaction's Routine is called... well, Reaction, it's fully unique. What you are thinking of is a routine I've dubbed "Tradeoff" since it's one enemy trading off for another and that is utilized by several enemies, Calbrena, Dr. Lugae, and the Fiends in the Giant of Babil are the most notable examples.

My take on all status-inflicting spell routines is that they are only good for the limited set of statuses for which they're intended.  Especially true with the status timers.  The "plain" status routine doesn't setup Count's timer, for example, or HP leak or poison...  Otherwise there is no good reason why there are multiple status related routines. I think it kept it simpler on the coders.  Actually that one might not even touch status bytes 3 and 4 if I'm remembering correctly, and hp leak and count are in those.

They are, you're right. But my plan was to set up the basic necessities of a Death status in the expiration of Count's Timer Load 80, store it in 28A3, then jump to the normal status routine...

For some reason it did not work. I tried an alternative method to load 0000 into an enemy's HP and they did die when their turn elapsed, but there was still that"only 2 can be killed by Count" enforced limit that I've had no luck locating.

 :blush: Yep there it is... 142: Dummy "Trigger a Reaction"  -  Between 141: Call and 143: Vanish   :isuck:   --  But in the future I also plan to call Spell # 173 "Tradeoff" - good call!   :terrydia:


Tradeoff reminds me of something I once read about Dummy Kefka:    http://finalfantasy.wikia.com/wiki/Kefka_(Boss)

"The dummy version of Kefka inherently has the Hide status so it never appears and cannot be targeted. The AI script of the dummy implies that the enemy was a device used to help switch the tiers in the final battle. However, since the enemy does not actually appear in the final battle, the enemy is a dummied enemy."

One thing that might work - though not ideal - could be (if I'm understanding this correctly) to stagger the deaths. Say if there were three Imps (A, B & C) - and they all had Count with turn order A-B-C. A dies...B dies...and normally at this point the game would lock up while trying to kill C, correct? What if part the count routine was to increment the counts of others that haven't hit zero yet. I sketched something out but retracted it while typing it up... I feel like there's got to be a way around this.  :hmm:

I liked 0000 HP - that should have been nice and clean. What about what I just did to Zeromus: 0000 for Imp-A, 0003 (With HP Leak) for Imp-B, and 0005 (With HP Leak) for Imp-C - then they'd go down like dominos. Not as clean, and it's getting further from Counts purpose of knock-knock--you're-dead...but then again, the way things are in this game sometimes it's just crazy enough to work.  :wink:

It's not so much that the game locks up when you use Count thrice, it's that the timer for Count just stops running and will stay at 0A, what does freeze the game is when you inflict it on many enemies at once.

You might be onto something with the Set HP to 0005 (HP Drain) or something like that to kill an enemy, but I think the way they've developed the status is probably the problem.

That's a nifty idea as a fix for Count. You'd have to get rid of the "Ran out of HP" message in order to complete the illusion, though.

Aww, thanks guys  :blush:   --  Perhaps we could banish the message along with its cousin: "Damaged By Poison"  :yabin:

And speaking of battle messages... is there a reason to keep "The Water is Gathering" - it has a visual...or am I neglecting something as I'm thinking it out in my head?

I think that battle just has a lot of unnecessary narration generally... "Hiding in the shell!" "The Lit scared him!"

Oh yeah - I forgot about those! So even in my head I was cutting that battle too much slack.  :tongue:

One legit reason I could have thought of could have been to somehow buffer the counters, etc. while the transition is taking place. But it didn't take long to counterexample that with Valvalis - when Kain hits her she stops spinning and they don't have to tell us about it...because they already told us to do it in the first place...  :bah:
