Final Fantasy Hacktics

Hi,

This happened only with FFTPatcher or you use some ASM Hack too ?

What are you meaning by changing his job ? Stats growth ? Name ? Look ?

Here is the gameshark code from patcher

300610E8 0021
30061118 0021
30061148 0021

All it does is changing the skillset of Ramza job to be Holy knight skillset. Not tested.

Hi, All you need is the patcher suit.

In FFTpacher, you can change his skillset abilities, you'll have to do it for all the chapters.
Shishi allows you to change his sprite (but i understood that you will keep it) but it can be buggy in some events (unless some more complicated job - i don't know exactly what yet)
If you want to change the class name to "holy knight" you'll have to use FFTactext.

Hi,

Here is my first patch attempt : FFTPatcher status conditional formulas.

This hack allow to set conditional statuses for any formula. To do so you'll have to check the box under learn on hit.
Once checked the routine will check Ability X value and will check if the statuses present in the Inflict status table (matching X value) are on the target. If Yes the formula keep going if not, it's a miss.
NB : if the chance to learn end by 01 The hack will take Ability Y as Status ID.

By default one of the statuses is enough, but if you check the bottom box of the status type (value 0x01 while all or nothing is 0x80) all the statuses are necessary.
If The 0x02 box is checked, then the conditional status will be deleted
If the 0x04 box is checked, then the conditional status will be copy on the caster. If both are checked, it'll look like an absorption

The formula that add statuses should work normaly (so this hack is a solution for necromancy - conditional death canceled and then add undead). To do so i had to hack the 0x80184B24 routine (* see notes)

If the formula is absorbed (elemental) reversed (undead) or nullified, the conditional status will not be canceled nor absorbed.
I've hacked the undead reversal formula (** see notes)

This hack use Kanji space (the very same place that in Xif video, because i know nothing about kanji space yet)
I attached the xml (made with Xif sheet) and the sheet (allowing to move the location of the used kanji space if necessary).

I do this very slowly, having few time (like many ), and i tried to check everything before releasing it, but i don't check it the hard way (not every status in every situation) just every function (with immortal, mounted innate etc .. units). I hope it will do the job. If you find bugs, i'll try to fix them (but again, slowly).

Thanks for all the people around here , their tutorials and all the wiki infos, for allowing me to do this. It kept me busy in hard times. Special thanks to Xif for it's video tutorial that make me feel i can do this.

NB : this is a milestone. I intend to implement other functions (patcher friendly) and rework the formula system. I hope it'll save enough space to not use kanji space.

*note 1 : i hack the formula to alter the "can't stack on" part, so it'll ignore the conditional statuses that are going to be canceled (and freed 34 lines)
**note 2 : i add some lines so if the formula is undead reversed it'll have the special flags 0x10 in current action special flags 2 (not used or unknowed ... nothing bad happened)

Hi,

It's in Emmy hacks. I just checked, it's in the patcher suit (but not in emmy's thread)

Hi,

Not sure to understand your problem.

I've two emulators : ePSXe and pSX (this one as a download link in the grey part juste under the "final fantasy tactics" banner.

It's seems both of them can load ISO, BIN or CUE.

Hmmm

In the Abandon_Calculation routine there is a jump to the weapon guard usability.

If it's no --> branch to the end of the routine.

Since there's no reference to the weapon guard ability itself, this routine is more a physic reaction ability check (at least weapon guard and abandon)...

But i don't get it, why calling this routine 2 times, rather than store the result and use it twice ?

Thanks for the reply.

If there is some piece of code that are'nt relevant, it'll make the understanding of it more difficult (for me at least).

For the depht i believe there's at least another river with 2 depht (i remember some character with the nose in the water)... 

But the way it's coded i think that float is checked ok, because the unit will be above water (and can use weapon guard)

For the chocobo part i never mount chocobo, but maybe they can swim and the unit will use weapon guard.

This frog and chicken thing will remain a mystery Maybe they swim too so they are checked (Independently of the fact that they can't use reaction ability...)

The end of the code is weird too, why r2 is multiplied by 2 !? in the return routine the only check is r2 <1 --> weapon guard usable (but writing this  i realize there is other return routine, the answer may be over there)

Hi, i ran into a section of code i don't understand (again)

001813bc: 00000000 nopThe routine returns r2 = 1 if you can't use weapon gaurd and r2 = 0 if you can

It checks several things :
- If the target as don't act --> r2 = 1  and branch to end
- If the target is being ridden (?) --> r2 = 1 and branch to end
- If depht is < 2 --> r2 = 0 and branch to end
At this point, the rest of the routine check for situations where the depht is >= 2
- If the target as chicken, frog or float --> r2 = 0 : ??? Ok for float but why frog and chicken ?!
- The end checks movements abilities that will get rid of depht

Frog and chicken can't use weapon guard do they ? 
Is there a game mechanics that i'm missing ?

And the being ridden control ? Which unit can be mounted and il using weapon guard ?

Nice !

Glad to have been helpful

Ok then,

if you are sure you have applied the xml correctly (to a savestate or an ISO ?)

You'll need to use a breakpoint at the golem adress and track another routine..

You also could ask on the discord, the bests ASMers may answer you

EDIT : i just read the discord channel, you obviously already know it

What happens ?

Does'nt work at all ? Or remains unchanged ?

Hi,

This problem also interests me.

I look for "golem" in the wiki (like niwit suggested)

I found those two routines  Main_Reaction_Routine_-_performs_ability_effects and Formula_01_-_06_Aftermath

In this routines, it seems that the amount of golem is stored at 8019000X (X = team) - 0x0A0C. --> 8018F5F4 (as mentionned in the Data/Table_Locations)

So i looked for 0X0AC and found this routine Main_Action_Routine_-_performs_ability_effects

Look's like there's a part of code that may be of interest in the main reaction routine and in the main action routine.

0018bfc8: a422f5f4 sh r2,-0x0a0c(r1)          Store Team's Golem Amount?
They both store the Target Max Hp as golem amount (the summoner is the target of the golem)...
I can't find anything else, and i'm not familiar with those routines, there's no return locations, i can't tell when they occurs..
I don't understand why the team as to be the enemy team..

EDIT : it's the same routine at two different links ! Probably the one to be changed

Thanks !

It worked fine.

I did wrong when i try to rezip the ressources folder. (the first subfolder was another "ressources" folder...)

Hi,

I've tried to edit an ability name in the ressources folder (generated by FFTPatcher), but it seems it's not working at all...
I 've failed to find a post that explain this in details.

I've found the xml file in the subfolder PSX-US/Ability but what next ? I've to import the file back ? Just zip the ressource folder back ?

Hi !

There's something I have in mind...

I've always been a bit frustrated to end up with the same team at every FFT run. A bunch of badasses with top brave and either top faith or minimal faith.

I like to imagine a system where having minimal brave could be an advantage (other than finding objects on the maps). It would require a lot of ASM coding, but also find something other than bravery and faith as stats name.

For bravery, I was leaning towards a couple of aggressivity/control.
- Above 50 a character would be aggressive and could receive bonuses for damage and certain offensive techniques. (and defensive maluses)
- Below 50 the character would have more control and would receive bonuses in hits, parry/blocking and certain defensive/monk/thief techniques. (and offensive maluses)

For the faith I imagined a couple of concentration/instinct.
- Above 50 the character would receive bonuses for the classic school of magic (= able to memorise and cast spells in the middle of the battlefield to the detriment of his sense of observation)
- Below 50 the character is instinctive and would gain bonuses in dodging (or even reduce the dodge of others) and would receive bonuses in "shamanic" magic (geomancer?).
This would suit Malak and Rafa quite well.

I'm not very satisfied with the terms I found (mainly concentration/instinct).
If someone has a an idea, I'm curious.
If someone has other ideas on how to change this faith/bravery system I am very curious !

Hi !

I'm a bit lost,

I started to complete the wiki while I was consulting its pages. Not very complicated things, putting links and filling in return locations.

I've just noticed that there are several ways of doing things (which may not be a good thing).
Sometimes it is the first line of the formula/routine that is indicated, sometimes it is the exact line of the return that is indicated .

I can understand both ways, but I can't say which one is more appropriate... Is there a place where the writing rules are detailed or do we just have to rely on common sense?

Hi,

I can't tell if there is a way to highlight a square holding an item (i mean if you change the location, the highlighted square move too)

But i think there is a way to edit map itself. I can't say how, but there is some custom maps in this forum, if you dig a little you may find a way to do it.

Hi,

I'm trying to write some ASM formulas, and i run into this code (in formula 15)

001891d0: 3402007f ori r2,r0,0x007f
001891d4: 3c038019 lui r3,0x8019
001891d8: 8c632d90 lw r3,0x2d90(r3) r3 = target current action data pointer
001891dc: 00000000 nop
001891e0: a0620013 sb r2,0x0013(r3)  Set target CT to -127.
001891e4: 3c038019 lui r3,0x8019
001891e8: 8c632d90 lw r3,0x2d90(r3)
001891ec: 34020001 ori r2,r0,0x0001
001891f0: a0620025 sb r2,0x0025(r3) 
I understand what it does, but i'm wondering, why there is two sequences ending to lw r3, 0x2d90(r3) ? r3 is not modified by the command sb r2 0x0013(r3) does it ?

Probably a dumb question...
