OK, I just rewrote the weapon XA routine because it was a mess.

XA can be:
PA
MA
(PA+SP)*.5
(PA+MA)*.5
[PA*Br*.01]
RN{1+[PA/2], PA+[PA/2]} (yes, before you ask, I did hack that last one in to replace the old RN{1...PA} formula because nobody liked the axe/bag/flail formula)
It also leaves some extra space for people who want to hack new formulas/make older ones more complex.   For anyone interested, you can now make a quick spreadsheet that can make any weapon type use any existing formula type.  All you have to do is change the branch offsets to the start of the appropriate formula type.

The following documentation is mostly SA's, though I fixed a few bits (code is now in little-endian).  All the offsets posted are RAM so you must subtract 0x67000 to get the BATTLE.BIN offset (which is 0x11EA9C).

The dogmas of every era are nothing but the fantasies of those in power; their dreams are our waking nightmares.

All right, here's another variant of the above routine.  This one, unfortunately, has no free-space, but it consolidates both the routines from http://ffhacktics.com/smf/index.php?topic=6548.0 without any more writes to Kanji space.

Given below is just the code in ASM and hex, so it is easy to C/P or analyze this.

Known bugs:
1) Displayed pre-attack damage on flails/axes/bags is still normal
2) Guns now take evasion if you use Formula 01
3) Revised routine cannot use Formula 01 for damage on non-attack skills correctly if setup is RH: Nothing/LH: Shield (this I'll try to fix)

The revised version should be a grab for anyone planning to use formula 01 or 02 for abilities. It fixes the Gun bug, meaning no abuse for 999 damage anymore.

Running it in Arena, it seems to be causing some crashes. Happened twice so far, once for a Gobbledeguck, and once for a Mime. It has not happen to player controlled units yet. Not sure about vanilla though.

Now This needs a spreadsheet! But would it really be easy to make a spreadsheet of this? Hmm... all in all it seems a bit... complex for ordinary people to easily use, any thoughts to making this into a spreadsheet Raven by chance?

All in all great work there fellows!

It's complex because I don't have a data table.  What you want to edit are where the beq commands are branching to.

Hack is still crashing for fists on ePSXe. Doesn't happen on the exact same ISO for psxfin. Not sure about pSX.

And it only happens for fist attacks.

EDIT: Seems like it only happens in my Arena ISO. I'll work out what is wrong later. The hack works fine in a vanilla ISO.

FFM noticed that Martial Arts boosts all attacks other than weapon attacks using 01.  Here's a fix.

NOTE: This overrides every single existing hack that addresses 2 Hands, Martial Arts, or ATTACK UP.  This also overrides the ability for martial arts to boost STEAL, PUNCH ART, or Throw Stone if you are equipping a weapon.

I deliberately coded the above hack with free-space so for those of you who want to write routines that allow for 2 Hands/Martial Arts/ATKUP having different multipliers, there's plenty of space for you to do so.  There's also enough space at the end to write a check for a new physical support ability.
The destruction of the will is the rape of the mind.
The dogmas of every era are nothing but the fantasies of those in power; their dreams are our waking nightmares.

Quote from: formerdeathcorps on June 29, 2011, 09:02:25 amThis also overrides the ability for martial arts to boost STEAL, PUNCH ART, or Throw Stone if you are equipping a weapon.


This bit kinda sucks, you lose a noteable bit of character customization with it.  (Mostly, the choice to go random dipshit with Ice Brand / Ice Shield / etc... Primary Skillset / Punch Art or Steal / etc... for the higher Punch Art boost over Attack UP or the choice to for whatever reason use an Equip X Monk, etc.)  Is there no particular way to fix it without over 9000 headaches?

This looks like it's near the point I can finally begin putting it to spreadsheet though.

FDC.... Punch Art, Steal, Throw Stone, and a few other formulas aren't checked in that section for Martial Arts. They are checked in the second section for Martial Arts at ram 0018614c.
