What the crap with Avon. I'd have sworn I fixed that. Maybe I somehow ended up making the Twin changes on a ROM that was pre-Invincibility fix?
Well, I'll have to go back and fix that again. I'm working inventory late tonight, so maybe tomorrow. Glad to see everything else seems to be in order.
I think it's kinda cool that you're coming up with ways to bork my game, btw. In some bizarre sense it makes the game more similar to the original.

Putting this demo out has re-sparked my enthusiasm for this hack. I keep coming up with little bits and pieces that I want to work in. I have to re-do Jinn so he has his sprite change (and of course fix invincibility), but then I'm going to get back to writing more of the story. In chapter two you have the option of hiring Ruby or Cinna to help out. Bet you can't guess where the next REMA mission will take Furio!

I also spliced Grimoire LD's Salve command into my hack, but I made a very slight change...

The BCS $36 at 03/E303 - I changed it to BCS $E6.
What this does is, if the item is above the last usable battle item (Heal potion), instead of returning a "failed" message, it moves on to check the next item. So now, Avon will Salve the first usable item in the party's inventory.

Latest version linked on the first post. Now including:
-Final revisions to Twin command
-Updated Salve command
-Updated credits sequence

Alright, I put on my supercool trench coat and Neo shades for this one...


I made a fix for the Dominant Twin problem.
Mind you, this is very specific to my hack, but the principle can transfer to other work as well.
Essentially, this gives Porom a new command (also called "Twin") that forces Palom to use Twin immediately, using targeting specified by Porom's command.
For my hack, I took over Boast (the last unused command), and had to squeeze the code into a bunch of different empty spaces (thereby using up just about every last bit of the 30000 block).

Here's the disassembly. Excuse the jumps - they were necessary to work around code that can't be moved at this point.

$03/FFFE 60          RTS    ;Return
An added bonus to this - the real Twin command (the one Palom has) can be used on one/all enemies allies but defaults to the enemy side; Porom's Twin command can too, but defaults to the Ally side (implying that Palom prefers the offensive but Porom prefers the restorative.

Good to know, Dragonsbrethren, but the portrait was just an example (because it was easy to show).
Does YY-CHR have other-sized modes as well like, say, 16x24 for (most) battle characters?
If so, then this is probably something I should have.

UPDATE
You're absolutely right, Grimoire. I think this was actually a case of subpar testing on my part...
 :isuck:
Porom won't use Twin on all party members unless she's in slot 1.
 :lame:

 :edit: OK, I figured out why my tests worked fine. Porom will target all party members as long as she is in an earlier slot than Palom. So if she's in slot 2 and Palom's in slot 3 through 5, no problem. The dominant twin bug happens if Palom is in an earlier slot. It's one of those things that is bothersome, but I think I can (grudgingly) live with. Maybe someday I'll investigate the matter more, but I've got too many other things I want to work on right now.

Updated patch linked in the original post.

Still need to patch in Grimoire LD's version of Salve, as well as update the credits. Both will happen soon.

Regarding the Agart minibosses - now they don't disappear, they just say "don't hurt me!" After you defeat them. I tried a couple of different fixes, but nothing else solved the problem of the phantom minibosses. This was my least favorite option, but at least it works smoothly now.

I tested with her in slots 1 and 5 and it works fine, though palom may have been in slot 1 when porom was in 5, if that would make any difference...

Regarding level up data... I think it's the same regardless of version - 7B700 (pointers) and 7B728 (data)

So my altered Twin routine works like a charm!
As above, the targeting (at 9FFD3) was changed from 60 to 70, so that the player can target one/all enemies/allies.
Also, the following spells were changed:
40 WMeteo (formerly Comet)
5E Esuna (formerly W.Meteo, now the same as Heal, except it can target all allies)
5F W.Cure (formerly the Dummy used - I think - by the Rod, now a really strong Cure spell)

The coding changes are thus:

Voila!

Now, for those who might be interested in using this in their own hacks, beware, this takes out the special consideration for which spell to use if the caster is Golbez or FuSoYa... which means there's a chance they will cast Flare on Zemus. At the very least, this would require a slight alteration of dialogue ("Use the Meteo!" Then they cast Flare?).

Quick update on progress (because v 0.2 is taking longer that originally planned)...

I've fixed all of the bugs Grimoire LD pointed out, except I haven't looked into Avon's invincibility not ending yet. I'm sure that will be a relatively quick fix, though, as it'sworked just fine in previous tests.

Oh, also, still trying to figure out the best course of action to deal with the occasional Agart minibosses not truly deactivating bug...

Additionally, fixed the level-up spell learning.

JCE3000GT made a title screen for me. Interestingly enough, when I patched that in the mysterious save game HP display bug stopped happening. Not sure if that was an intentional easter egg he threw in there...

Turns out, there WAS a since-corrected issue with FF4kster that caused DKnight and Paladin slots to have the same name. So now Blank fully uses DK Cecil's slot, which means:
-no need for a level-up workaround patch. All levelups work fine now.
-no more problems with Twincasting. Rydia will still get drawn in if she's in the party, but in the actual game she never will be.

What's been taking so long is the rest of my hacked Twin command. I've figured out (pretty sure) a way to allow it to use white or black-type spells, player's choice, without sacrificing the randomness factor.
Essentially, I cut out the Golbez/FuSoYa checks in the spell chooser, then did the following (I'll post an actual disassembly soon):
-set register Y to 0000
-load caster's enemy targeting byte
-if not 00, skip ahead
-if 00, set register Y to 0015 (15 is the difference between spell numbers of flare and w.meteo)
-RNG
-if RN = FF, normal fail routine
-if RN is over 40, skip ahead
-if RN is less than 40, +1 to register Y
-transfer Y to A
-add 40 to A
-rest of routine as normal
Also, changed the targeting options to split enemy/ally (defaults to enemy), replaced Comet with W.Meteo, and replaced W.Meteo and the dummy that follows it with a powerful cure spell ("W.Cure") and a target-all heal spell ("Esuna") respectively.

The result: if the player chooses to target one or all enemies, the game randomly chooses spell 40 or 41 (W.Meteo or Flare). If the player targets one or all allies, the game picks between 5E and 5F (W.Cure or Esuna).

I had planned to finish all of that yesterday, but then I accidentally spent the whole day investigating spell AV code (trying to write a unique image for W.Cure to visually distinguish it from Cure 4 and Cure Z). Not a significant amount of success there, though I discovered a few interesting things that on their own are no help. I may cut my losses for now in the interest of getting an updated patch out there.

So that's where I'm at right now, in case anyone was wondering.

I was looking at Blank's level up table and I remembered what the issue is there.
The problem is, he uses DK Cecil's job slot and level up data, but Golbez's Actor and Character slot. This was the workaround to ensure he wouldn't have the same name as Ceo, who uses P Cecil's spot (as I recall, DK Cecil and P Cecil must have the same name, unless that was just a since-fixed bug in earlier versions of FF4kster).
Anyway, an unintended side effect of this is that Blank... is not fully compatible with FF4kster.
In some respects, that fact's just a minor inconvenience - to add him into the party, you simply "add DK Cecil," but to remove him, you have to "Remove Golbez," which is not an available option in FF4kster. So, I make the event remove DK Cecil, then edit it by hand in my hex editor. A sliver tedious, but no big deal.
For level up data, though, Blank is an ungodly nightmare. FF4kster can write his level up data just fine. Problem is, it can't read his level up data. So any time I edit any part of the ROM with FF4kster, his level up table gets screwed up again. Of course, now that I know this, and I am much better at all of this than I was when I first started this hack, I know I can fix his data once, then just make a patch that can be applied when needed. But I've gotta find the time (and motivation) to sit down and fix his level up data one more time - probably the most tedious FFIV hacking task in existence imho.
The good news is, that's the only issue with level up data. It seems, in my experience, that TNL only gets screwed up if you try to make a character begin at a level earlier than they normally would. My characters' level up tables all start at the same level or later. ...Unless there's an issue I haven't discovered yet...

Here's my spriting process:

1) Open ROM file in Tile Layer - This may work with other programs, but I know it works with Tile Layer
Jump to the offset of the image you're editing, and highlight it by right clicking on the first sprite and dragging to the last sprite


2) Export the image to a bmp file


3) Open the bmp in MS Paint. Don't waste your time and effort on a fancy image editing program. Remember, you're editing an image that is, at most, 16 colors, and probably no bigger than 32x32 (unless you're making monsters, but still...). Paint has all the tools you'll need for this process, and won't muddy it up with too many tools you won't need


4) Zoom in as large as possible - 800% for my version of Paint


5)In the Zoom menu, select "Show Grid"




6) Expand your image workspace by clicking on the dot in the center of the lower edge of the image and dragging down. Give yourself lots of room.


7) Arrange the image - by selecting, copying and pasting - into this newly created space.


8) Helpful tip: Create Gridlines around your arranged image so you know the limits of each individual sprite.
Also, create a working palette of all of the colors. DON'T use any other color, or Tile Layer will not properly interpret it when you're done.


9) Create your new image


10) When you're done, drag the newly created image sprites back into the space from which they originated




11) Then, reduce the image back to it's original size (ckick and drag that same dot)


12) Save your image (no need to "Save As")


13) Back in Tile Layer, import your image




14) Drag the imported image to its desired location


15) Click in the data area, somewhere other than the imported image, to make the grid reappear over it. this is a necessary step to complete the import.


16) Save your ROM, and voila!



Sounds so easy, doesn't it?
It's not. I'm dreading any and all of this that I'll have to do in the future for my hack, but, well, it's a necessary evil.

Hope that helps!

Palettes are not so complicated when you use SNESPal, as long as you know where the palettes are located
Spriting, on the other hand, is an extremely complicated and even moreso time consuming process. I spent the better part of a month just putting the characters' images together - which is exactly why I ended up with some I am not completely fond of.
I'll explain my process with some pictures soon.
