FF3SE-M

This patch relocalize the monsters graphics and their composition data respectively in the F2 and F1 bank of a 32Mbit expanded FF3US 1.0 rom with a header. The rom this patch is made from was expanded with FF3usME. You should do the same before applying the patch.

The goal of the patch is to relocate those data to a place where we could expand them with an editor, in this case FF3SE. This patch has not really a purpose if you do not use with a modified version of FF3SE (included in the downloadable package), unless you can convert a monster sprite to hex data and paste it in the rom.

You can still use FF3usME after applying the patch but you will be unable to see the monsters sprites or their molds(8x8 tiles composition). It's still possible however to edit formations and change the battle molds for instance.

The .rar archive include the patch, a modified version of FF3se, an anti-patch and two text files, one concerning the patch and the other the modified editor.

Those two files contains all the changes I made, in case someone wants to finish what I started.

The patch was extensively tested in normal battles and at the colosseum and even in special battles such as Kefka vs sabin&co and all the monsters graphics were loading properly.

If you find any problem with the patch, if you see that I missed something or if you find the bug or what is wrong with the modified editor, I would really like to know.

Here's the link to the page where the source of FF3se is available, for those who would be curious:

Here's a part of the readme.txt:

Old locations in the rom:

12AA20   12AA21  PTR  Pointer to 8-High Monster Composition Data
12AA22   12AA23  PTR  Pointer to 16-High Monster Composition Data
12AA24   12AE23 DATA  Monster 8-High Composition Data
12AE24   12B423 DATA  Monster 16-High Composition Data
297200   2CE3FF GFX  Monster Graphics

new locations in the rom:

31AA20   31AA21 PTR  Pointer to 8-High Monster Composition Data
31AA22   31AA23 PTR  Pointer to 16-High Monster Composition Data
31AA24   31AE23 DATA  Monster 8-High Composition Data *
31AE24   31B423 DATA  Monster 16-High Composition Data *
320000   3571FF GFX  Monster Graphics **

*Note that the Monster Composition Data can potentially ends at 31BE23
with the max space set in the modified FF3SE

**Note that the Monster Graphics data can potetially ends at 3671FF
 with the max space set in the modified FF3SE.
