The New FFIV

I'll look into this Djinn, would you like to try and help me with this part of the hack?

I just now applied the following font that took 3-5 minutes to import with YY-CHR. FF3usME's font creator is really nice for the big text fonts, but YY-CHR is better with the smaller fonts because of the copy and paste feature. I copy and pasted all of the text into YY-CHR overwriting the existing alphabet.

I'd like to give credit to the creator ... but RomHacking.net doesn't show who did it... on any of the fonts...
I think it was DragonsBretheren however.


-Twin Cast Notes-

Twin Cast: Uses Control as a base and selects four skills like Control normally does. These skills are:
-Pyroblast
-Twin Flare
-Comet
-Twin Meteor


A synopsis of this entire document is we can change the targeting of "Control" to choose any character on the battle instead of an enemy. We can designate a monsters skill set so each time control is used on a random monster, it'll use that designated monsters skill set. This is only if used on a monster, not on a player.
We cannot set it to load a monsters skill set if Control targets a character and we cannot set Control to target one specific character. To avoid exploitation of Twin Cast so that Palom or Porom doesn't cast it on themselves, it needs to either be disabled if the other twin isn't in the battle, or have it so it can only target the other twin who's not casting.
A log between Me, Lenophis and Angelo.

<Zeemis> Do you know where the data for where the ability Control is off the top of your head by any chance?
<Lenophis> what data?
<Zeemis> I want to try to change the targeting to target one character.
<Zeemis> once that player is targeted, it offers the skill Twin Meteor or Star Fall
<Zeemis> That seems like it'd be a bit to hard lol.
<Lenophis> CFFE00-CFFE7F - DATA
Command info, 2 bytes each. 0001 = Gogo can use command, 0002 = Can be mimicked, 0004 = Use when an Imp, FF00 = Aiming
<Zeemis> I believe the new version of FF3usME can do the targeting.
<Zeemis> Possibly:

<Zeemis> Something like: If Palom/Porom is affected by skill: Control
<Zeemis> Use "x" monsters skill set.
<Zeemis> And I change that monsters skill set.
<Zeemis> At the same time, the skills can be learned if cast on so twin magic can be learned
<Lenophis> you're talking about adding a lot of code
<Zeemis> But I'm still trying.

<Zeemis> oops.
<Zeemis> I think the command looks for a monster, reads up to 4 bytes from the script, and displays the skills
<Zeemis> [11:27:40 PM] neptuneknight1: Read 4 bytes from command script
<Zeemis> C2/1A6B: BF 00 87 CF LDA $CF8700,X (Command scripts)
<Lenophis> ...
<Zeemis> This is Angelo who's helping me.
<Lenophis> right, 4 bytes for 4 possible commands
<Lenophis> for display and selection
<Zeemis> So 4 bytes total. 2 for displaying the menu and 2 for selecting an ability in the menu?
<Lenophis> no
<Lenophis> 4 for the 4 commands you pick from for that monster
<Lenophis> 1 byte per command
<Lenophis> per spell, per action, whatever
<Zeemis> what we need to do then is diable the function of the command so it loads only two bytes - corresponding to star fall and twin meteor
<Zeemis> ^ Angelo.
<Zeemis> yeah, it reads 4 bytes - some monsters have fewer bytes
<Lenophis> all monsters have the same
<Lenophis> just some are FF (no selection)
<Zeemis> but there's code we need to disable so the command doesn't go looking for all the enemies in the game
<Zeemis> [11:34:40 PM] Zεεຕใร: Do you know how to change it from trying to load a monster skill set once used on a particular character?

<Zeemis> C2/1A6F: 8D 2C 3A STA $3A2C
<Zeemis> Maybe it has something to do with those lines
<Zeemis> are the monster's scripts located at CF/8700?
<Lenophis> CF8700-CF9FEE MONST Monster AI scripts <--
<Lenophis> not what you are looking for
<Lenophis> CF3D00-CF42FF MONST "Control" command attacks (384 enemies, 4 commands per enemy)
<Lenophis> CF4300-CF45FF MONST "Sketch" command attacks (384 enemies, 2 commands per enemy)
<Lenophis> CF4600-CF47FF MONST "Rage" command attacks (256 enemies, 2 commands per enemy)
<Lenophis> that's what you want
<Lenophis> I need to sleep
<Zeemis> Alright
<Zeemis> Thanks for the help.
