Is possible to do this?

Glain · June 11, 2012, 04:27:32 pm

1. From what I can tell from looking at those routines briefly, "counter" is the index (number) of the status effect that is currently being checked (1=Crystal, 2=Dead, 3=Undead, etc... check Data Locations.txt). There are a total of 40 (0x28).

2. r4=0 is the result.
That statement is better read as: addiu r4,r5,-0x18 (r4 = r5 - 0x18).
As a general rule, if the immediate given to addiu is >= 0x8000, then it's actually a negative number: (0x10000 - immediate) * -1

Ok Thanks.

I really oNly interested in two hacks, the gear hack for my guide, and the CT Wall in to cused Status.

1 Glain, Have you comment the routine at 0x125028? I don´t undestand what is load really in r2 when load ''the variable shop current abailabity based in story progression''

2 I have a question, I was think about graphic data of status. Pride mencioned that someone find a lot of graphic data. Who is this ''someone'' and what he find? and anyone how is loaded this graphic data, and how in stored in an status?

In complement, I was think (not necesary) I was think in edit the mp hacks, in the way that: Units recover 10 mp when the unit turn start, and the mp recovery isn't showed. Now, I do this: Units start with 10 mp and recover 10 mp at the end of his turn. A way to do the mp recovery isn't displayed?

I don't have that routine commented. What I found is that when I went into a shop, the shop availability number was loaded from the two lines of code starting at 0x125028 in world.bin. As it stands, that code is currently:

jal 0x000ef1a8
ori r4,r0,0x006f

You can replace the shop availability with the highest party level by putting this code at 0x125028:

lui r2,0x8006
lbu r2,0x6308(r2)

Basicaly is where the las 16 Status CT is decrement, when activated, and how the CT removed the correspondent status. The routine does this using a counter, from 0 to 15, with each one does I said before. Creating an exception for Wall Status I writed this:

<Patch name="Cursed status use Wall CT">
<Description>Wall CT is always 0. Cursed CT is adjustable in ''Cursed CT'' in FFTPatcher</Description>

And... it works!
Only remains to do the Gear hack, I think I'm still silly

Rfh · June 22, 2012, 11:48:53 am

And the waited too gear hack:

<Patch name="Shop Availabity is based on your the maximium unit level in the party and the level for unlock each item is the value put in ''Enemy level'' in FFPatcher.">

Glain, after watching the routine that Calculate Highest Party Level, I see that the highest party level is always 99, but, I see that load the party level in r2, this work perfectaly. So ''Party Level'' is the maximium unit level in the party:

lui r2,0x8005
addiu r2,r2,0x7f74
lbu r2,0x0016(r2)
nop

I see too where is compared the shop availabity with the number of story progression, and I understand what I have to do.

Glain · June 22, 2012, 06:22:49 pm

Isn't that (0x57f74 + 0x16) Ramza's level? That won't work if Ramza isn't the highest level unit in the party.

I think you need to call the Calculate Highest Party Level routine:

jal 0x05cdb0
nop

Rfh · June 23, 2012, 11:10:59 am

It doesn't work, but the routine exist, because the ENTD flag in level ''party level'' load this.
One thing, Anyone can explain me why the damage isn't showed in formula 64?

Glain · June 23, 2012, 09:49:55 pm

Does the Calculate Highest Party Level routine load the wrong number into r2? I'm looking at the code and am not really understanding why it wouldn't work. It also should always be in memory since it's an SCUS function.
