While adding in some ASM hacks,

[Pickle Girl Fanboy]

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.

[LastingDawn]

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!

[Pickle Girl Fanboy]

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?

[Pickle Girl Fanboy]

Bumping to get more attention for the tests above.

[LastingDawn]

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!

[Pickle Girl Fanboy]

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.

[Vanya]

Interesting. Maybe these are item attribute tables? Have you tried modifying any of the other values?

[Pickle Girl Fanboy]

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.

[Vanya]

Are you certain that Razele's hack affects the katana weapon powers too?

A katana's attack power is, if Razele and these tests are right, it's break rate.  Possibly out of 128.

[Vanya]

An asm hack might be in order.

[Pickle Girl Fanboy]

Of what?

[Kaijyuu]

To make weapon power and break chance different values.

Probably just some pointer rearrangement.

[Pickle Girl Fanboy]

Beyond my abilities.  For now.

[Vanya]

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.
