Final Fantasy Hacktics

This hack is a Massive formula Hack. It merges all formulas in a single one. Each previous formula now are a table of flags, allowing to build XA&YA and to trigger various vanilla mechanics.
Some of these mechanics are not managed with the formula but with the abilities flag.
The main hack : TOFU suit is mandatory. you have to use it if you want to use any of the other tools
I tried to stick to the vanilla routines. The idea was to keep it compatible with some existing hacks but since i've not tested any hacks yet. Try or Ask first.

In very short : all formulas can support status, evasion, faith, elements, item breakage etc..

What does it changes if you patch your ISO and don't change anything ?

What can you do with Patcher ? : All formulas take status, evasion, faith, elements, item breakage etc...

TOFU Maker is done !
While using TOFU Hack, you can use this tool to customize every formula of the game !
For now, only vanilla features are supported, but there is room to add more mechanics. (Throw some ideas !)

A big thanks to Xifanie and his marvelous FFT Hack Template Spreadsheet !

I post here an Excel file i made to help me to mod, track and test abilities,formulas, skillsets and Jobs.
It's just an overview, linking some usefull infos.



There's 2 versions filled with TLW data :
- The light version contains just data.
- The complete version comes with formulas and can be filled with different data. You can copy Other data using MassHexASM from SCUS  (ability formulas, job, , skillsets) and BATTLE.BIN (effects). You can also change skillset and Job names if needed.


EDIT : Xif have done an amazing tool that far more this one is doing (but the list of formulas) :FFT Mod Helper v1.03

The ability proc data is stored in 0x801938c8 and 0x801938c6 those 2 locations are cleared by the routine called in barrage formula (Switch_Ability_to_default_Attack)

So there is no chances to proc holy nor any other ability.

Quote from: nitwit on August 03, 2022, 09:07:23 pmTreat it like a range (0 to 4), basically? I could accomplish that by bit shifting it and masking out the parts I don't need, though I don't know if that would be simpler in ASM than dealing with bits and branches.

You might achieve that, but still the weapon and the shield section are peculiar. Shield section check the 2 hands, weapon section too, but it compare the two weapons to choose the one to break... So in the end you'll have to deal with some branches i guess.

Ho man ! That's a ton of details...

I can't answer all of this point at once. And even if i would to, i don't have the required skills.

I can't answer you for the AI, i've no experience with it yet. (All i know is that when i write a hack that adds a support ability adding fire to weapon element, AI was smart enough to figure it).

If you want to spare some bit you can use the ability AI flags too.
Affect MP --> MP damage
Affect stat to point to the stat section (unequip for break/steal)
Undead reverse for absorption (but you'll have to implement real undead absorption for the AI sake)
Target enemy for damage, target ally for heal.

Your signed Y from -4 to 3 is more easy if you using a bitmask then using sll 0x05 then sra 0x05 (100 is - 4 and 111 is -1)

For the break/steal info, you can save some bit too, no need to use one bit per equipment part since you won't be able to break/steal more than one slot per action (not without writing a lot a stuff i guess). so bit 7 alone is weapon, bit 6 alone is armor, bit 7 and bit 6 is shield etc...

Hi,

Changing the Jal should work just fine (used weapon ID is ok with swordskills.

I'm not sure for the require sword things, because i haven't deal with this yet. But i don't see why you couldn't grab the weapon characteristics instead of ID or type. (you can use the ARH hack too)

Not sure to understand the integrate thing with swordskills formulas. You mean merge them into one ? It's doable of course but it's more complicated.

Logical or is possible (i've done it) but you'll have to write these lines. (I merge the ability and weapon element if weapon strike or weapon range is checked in patcher)

Y signed is possible, i have not messed with it, but i would start by changing the loading and maths instructions (suppressing the "u")

Switching to unarmed formula ? you mean just the XA and YA ? or a totally different formula ? If you want to alter XA and YA, i think you'll have to write a custom routine instead of using the base XA one. For a different formula, you can jump directly into it and then exit 0x2d directly as soon as you return from the jal.

Nop. Not with the Patcher

You might found some hacks in FFTorgASM library

For the ennemies on field FFTPatcher is what you need. (Tools section)
For the squad size, You will need this : https://ffhacktics.com/smf/index.php?topic=9749.0

Not sure there's a tuto. But it's quite intuitive. You'll have to try and see what happens.

You could do that in FFTPatcher. You will find it in the Hacking/Tools section of this forum

In vanilla statuses do not share a timer. So there is no list.

The two first in the list are Poison and regen. But since Poison infliction cancels Regen, and that Regen infliction cancels poison, they are a perfect example of two statuses that can share a timer (since they can not be inflicted at the same time).

Innocent and Faith are another example, as Haste and Slow... etc you can check/set in Patcher which status cancels what.

Hi,

In patcher you can edit the CT value of the statuses that already have a CT. But some statuses are hard coded to not have a CT (for example petrify will never go away).
Every unit has 16 "slots" to manage their status CT :

0x005D Poison CT
0x005E Regen CT
0x005F Protect CT
0x0060 Shell CT
0x0061 Haste CT
0x0062 Slow CT
0x0063 Stop CT
0x0064 Wall CT
0x0065 Faith CT
0x0066 Innocent CT
0x0067 Charm CT
0x0068 Sleep CT
0x0069 Don't Move CT
0x006A Don't Act CT
0x006B Reflect CT
0x006C Death Sentence CT

Every other status CT will just be ignored unless you are using Pride's hack.

Hi,

Here. Tested only by patching a save state. It should work the same patched to an ISO.

Update 22/11/2023.
Initial Hack alters all abilities. I rename it and post a fixed one (yhanks to Sardek to point the mistake)

Hi everyone,

I rewrite the routine setting rotation matrix elements to GTE. Three_Angle_Sine_and_Cosine_Maths
The routine is 9 lines shorter and free some space in SCUS. from 0x8002c6ec to 0x8002fee4SCUSFree0x37f8.xml

If you use psxfin there's a key to free framerate (default is backspace)

Hi,

The salvage skill is a good idea. But you'll have to allow that ability to target dead unit.
I think that you can target a dead unit only if the ability is going to cancel death. It's possible but it'll require some ASM skills.
It happens here Set_some_data_for_current_attack The routine is called in Pre formula set up routine just after the return from the formulas.

And there might be others checks in the routines that modify target equipment...

Hi,

You're probably right for bloodsuck (i don't use it at all, and i can remember only one combat where it was a problem)

For death sentence, it's because of the 3 turns delay. Since in vanilla you can kill anybody in 2 blows (if not one), i never use it.

Assuming they've a 100% hit. And i guess it's very subjective and bound to my way to play the game

Hi,

It's something i was thinking about too.

I went to something slightly different :
- Healing + absorb --> the Heal is boosted
- Healing + cancel --> No Heal (taking it as an immunity to that element)
- Healing + Weak --> Half the heal (like if the target is uncompatible to that element)
- Healing + Half --> Normal amount : it's a heal, there's nothing to resist at. it could be think as an affinity to the element too (with a slight boost).

Hi,

Not sure to understand your problem.

Memcardrex (1.8) can convert opened .mcr into .gme (via save as)

Yes, it's quite simple.

Watch this tutorial : https://ffhacktics.com/smf/index.php?topic=12477.0 : at the beginning of the first video Xifanie point to three formulas. You just have to follow the same steps with the formula you want.
