PSX FFT Hacking / Grond's ASM patches
April 18, 2023, 08:17:51 pm
My ASM patches. XMLs attached at bottom of post.
The 'Half of MP and Short Charge' xml is a couple of old patches, but now fixed up with AI functions.
The 'Random Battle Music' xml lets you choose which four songs you want to play during random battles.

<Patch name="Formula 2E (Mighty Sword) has X% chance to break equipment">
<Description>Also gets PA*(WP+Y) and 100% status like the base game Holy Sword skills.
! The 0-100% chance to break equipment must be set under X for each ability in FFTPatcher, or nothing will ever break.
! This patch does not affect the hardcoding of formula 2E's equipment breaking to ability slots A0-A3. The formula can be used in other slots without equipment breaking, however.
This is an edit/fix of Choto's Mighty Sword Hack. From his description of it: "This makes it so that the mighty swordskills have a % chance to break equipment, but always function as normal damage swordskills. Maintenance prevents item breakage, but not damage. (...) I also (...) divided the damage by 2 to prevent roflstomping." </Description>

<Description>! Do not try to apply this at the same time as the main Formula 13 patch above, or FFTorgASM may detect a 'conflict' (that is intentional in this case) and move the patch out of the space intended for it!
! Requires 'Swordskill damage becomes ((PA+MA)/2)*(WP+Y) - Master routine'!
This is only for the above 'Formula 13 becomes Damage=(PA*(WP+Y))+Absorb HP+MP' patch.</Description>

PSX FFT Hacking / Buggy ASM hacks
March 24, 2014, 02:00:32 pm
Hello, FFHacktics regulars! Does anyone have fixed versions of these, or would anyone care to fix these? I would like to use them in a major mod I am working on; otherwise I will have to design around not being able to use them.

To verify that the problems I'm having with them aren't the result of conlicts with other patches, I tested them all individually with pSX v1.13 on a clean/vanilla ISO (except for changes necessary for an ASM to be usable in-game).

Disable Move hack by FFMaster
   http://ffhacktics.com/smf/index.php?topic=5658.msg155233#msg155233
   Just doesn't work more often than not, but occasionally it will function correctly.

Units with reaction between Counter and Distribute have front evasion for sides and back by FFMaster
   Seems to affect everyone and is not limited to units using the ability, as described.

Learning Support Hack by pokeytax
   Technically works, but also screws up equipment and/or stats.
Test scenario 1:
   I set up the patch to utilize the blank support ability under Non-charge and using job Calculator and skillset Math Skill. Made the new 'learning' ability cost 0 JP and added it to Math Skill skillset. Added Flame Attack to Math Skill skillset and make it 100% learn-on-hit, non-learnable with JP, and cost 9999 JP. Added Flame Attack to Bomb's skillset. In-game, equipped 'learning' on a weaponless non-Calculator and let a Bomb hit him with Flame Attack. Result: learned Flame Attack as expected, but also ended up with an Asura Knife mysteriously equipped in the right hand.
Test scenario 2:
   Same as 1, but I sent the unit in as a Calculator without the 'learning' ability and ended up with a Yoichi Bow in my hands out of nowhere.
Test scenario 3:
   Same basic setup as 1, but changed from Calculator to Mediator, a more ordinary job/skillset in hopes that it wouldn't bug out like Calculator. Ended up with a Rod equipped in the body armor slot.
Test scenario 4:
   Same as 3, but I sent the unit in as a Mediator without the 'learning' ability and ended up with a Spell Edge in the body armor slot.
I stopped this test here, but I've had this patch give me many hundreds of MP in the past instead of (or in addition to) altering equipment.

Multiplier Editor in Raven's Workbooks
   Tested these with the default values provided. Using the "Haste, Slow Edits" portion caused battles to start out stuck in some sort of infinite loop with everyone walking in slow motion. In the "Element Fixes and Edits" portion, elemental weakness is completely broken. I didn't test any further with that part. In the "Attack Up, (etc.) Edits" portion, Attack Up tested with a Mithril Gun (64 base dmg) against a freshly-hired neutral-compatibility Squire deals 80 dmg (125%) instead of the expected 85dmg (133%). I stopped testing here.

Blank support ability over Short Charge adds 25% bonus skill hit by Xifanie
   I noticed there are two* different versions of this, one in Xifanie's ASM thread and one in an xml included in v483 of the patcher suite. The former seems to work okay, actually, though I haven't tested it a lot. The latter version doesn't seem to do anything at all. Why does the (newer?) version in the xml exist? Is it supposed to be fixed to work on a real PS1 or something?
   *Choto has a modification of this patch that also has issues, but I posted about that in his ASM thread (which is still active unlike most) so hopefully he can fix it.
