Need help yet again - Sorting of items and materia

[DLPB_]

I do not understand the technical aspect of how the game arranges materia and items in FF7.  From what I can gather the matera and items have an ID and a table which tells it how to order.  Let's start with the materia.

In order to reduce the number of textures the game uses and to place the materia onto the correct texture (colour wise) I had to also alter the texture ID of the 5 materias.  These 5 ID's (1 byte each) are found at:

0091ABF0-0091ABF4

The problem is the game also uses these to arrange materia by colour.  So now when I choose arrange, the Summon materia is first on the list and others are not in the correct order as the original.

A way to change this via assembly would be helpful or I will have to be sloppy and alter the textures in adobe photoshop.  I have noticed 2 areas that seem to be most involved with reordering:

006CBCF3 and 0070e5da

It could also be that I am missing the point here and that the ID's I changed are just associating colour with materia and elsewhere there is code or table telling it how to go into the colour order.

===========

For items, it shouldn't be much of a problem to alter the tables so that "By name" works with my re-translated names and not the originals.  I can probably find this on my own but we will see.


Any help appreciated.

Dziugo has fixed it.  He is a God.  How the f*ck you can be this good is beyond me.

As for the problem - the table you've changed was not actually a graphic lookup table, but more like a rank lookup table. If you want to keep the actual graphics for each materia you have to somehow rollback the changes. The code:

Rollback rank table is located at 0070E612 and right now it does nothing - just change the numbers there. Should be something like this:

Code: [Select]

00 01 0A 09 04 05 08 07 08 09So incoming 02 becomes 0A (as it was before).

Just documenting some findings here:

Ordering table for items starts at 00921548 memory.

 Items with id  0069-007fh are unused.
Item 00FF is Sephiroth's sword Masamune and is hidden from item menu because it has been assigned 0099h.  0099h appears to tell the menu not to display item.

There are a total of 296 used items, 1 hidden (masamune) and 23 unused.  Total therefore of maximum number 320

You can get Masamune back in the item list by changing 2 bytes in the order table,

memory address 00921746, change bytes 9900 to 4001.

that will place it right at bottom of the item list.

I reading your menssages...your a MONSTER!!! Always thanks for your contribution in forum
I much interesed in this! You think with try change values of support can activate materia "booster"? I can try ...in this moment contruction of mod and want modify all possible! I surprise in never of forum talking of this materia >.>

I am afraid at the moment I am swamped in 2 projects and a project elsewhere, but if I get time I will have a look.  Perhaps someone else here can have a look too
