Title: While adding in some ASM hacks,

I noticed something. Look at the attachment. Just under the Chirijiraiden's break %, the table continues on. What is this?
I'm hooked. I'm gonna make a table of it, and look for it in a save state.

I had seen that too, but was too pressed for time to really worry about it, it was intriguing though! Best of luck with decoding it!

In SCUS, starts at 0x542B8, ends at 0x546B7. A similar bit of hex, almost exactly the same, starts at 0x63D68 and ends at 0x64167 in *.psv save state

I don't have acces to MS Word or Excel, so I can't use (Table-->Convert-->Text to Table) to insert the Base Addresses. If you add -0x2B0 (yes, that is a negative 0x2B0) to the *.psv Base Addresses, that could be where they are in the RAM. I could be wrong though.
EDIT Testing Gameshark code 30063C34-0000 to see if it alters Chirijiraden's break rate.
Later... It does, but not how I expected.
Test 1: 30063C34-0000 Attacked 10 times with Chirijiraiden Draw Out Skill. Broke zero Katanas. Also, note that the attack power of the Chirijiraiden katana I had equipped was reduced to zero.
Test 2: 30063C34-0064 Attacked 10 times with Chirijiraiden Draw Out Skill. Broke 7 Katanas. Also, note that the attack power of the Chirijiraiden katana I had equipped was increased to 100.
Not sure where to go from here. Razael's ASM Hack does affect Break Rates, but it also affects attack power of the corresponding katana. I'm done until I think of any new tests.
Something's bothering me... Isn't there already a place for a weapon's attack power? Why the duplicate?

Bumping to get more attention for the tests above.

Very interesting results... I wonder why the duplicate, and as it is a duplicate I wonder why it has precedence over the actual WP? Keep up the good work!

I just finished looking through the gameshark guide. This: 30063C34-00?? Is the code that modifies Chirijiraiden's Attack Power. When you modify that katana's attack power via FFTPatcher, you're doing the same thing. But this definitely modifies a katana's break rate when used as an ability. I guess a Katana's break rate is hard coded into it's attack power.

Interesting. Maybe these are item attribute tables? Have you tried modifying any of the other values?
Title:
Post by: Pickle Girl Fanboy on May 14, 2009, 05:04:36 pm
These are the item attributes modified by FFTPatcher. I don't know how Razele found that these modify Katana/Draw Out Break Rates, but they do.
Considering Test 2 had a 70% break rate, and I used 0x64, I think its out of 0x80. I'll test it with 0x80 soon.

Post by: Vanya on May 14, 2009, 05:08:59 pm
Are you certain that Razele's hack affects the katana weapon powers too?

Post by: Pickle Girl Fanboy on May 14, 2009, 05:12:31 pm
-=============- WEAPON BYTES II -=============-
BASEADDR +0 : range
BASEADDR +1 : 00 = one hand only 01 = requires both hands to hold 02 = ? 04 = Two Hands YES 08 = Two Swords YES 10 = fires line-of-sight or arc trajectory 20 = fires line-of-sight trajectory 40 = lunging weapon (spear, stick, cloth) 80 = striking weapon
BASEADDR +2 : 01 = normal 02 = randomly cast a spell 03 = used for gun 04 = used for elemental gun 06 = drain HP 07 = restore HP
BASEADDR +3 : always FF
BASEADDR +4 : weapon power
BASEADDR +5 : weapon evade%
BASEADDR +6 : elemental (see above)
BASEADDR +7 : spell to cast / status to add => You can mimic any spell's status-adding ability by looking that spell up in the `Abilities' chart above, and copying the BASEADDR +B from there to the BASEADDR +7 byte for your weapon => For random spellcasting, this is the index number of the spell. See the listing in part 7.
A katana's attack power is, if Razele and these tests are right, it's break rate. Possibly out of 128.

An asm hack might be in order.

Post by: Pickle Girl Fanboy on May 14, 2009, 05:29:44 pm
Of what?
Title:
Post by: Kaijyuu on May 14, 2009, 05:33:16 pm
To make weapon power and break chance different values.
Probably just some pointer rearrangement.

Post by: Pickle Girl Fanboy on May 14, 2009, 05:40:24 pm
Beyond my abilities. For now.

Post by: Vanya on May 14, 2009, 06:01:28 pm
It would require some extra space to make them separate values. However, to just remove there being a chance for them to break or giving them all the same static chance to break would be as simple as changing a few instructions in the code. Then it would just be a matter of finding the code pertaining to Draw Out. For some reason pSX isn't working on my current machine, otherwise I'd be ASM hacking already.
