Topic: Developing FF4kster: a comprehensive editor for FF4

[Grimoire LD]

Hmm, I just tested this and saw no issue. The first default Song was still "Nothing Happened" the second default one was Song of Silence, then Song of Charm, and Lullaby. There was no issue that I saw with an A9 becoming 2F.

[vivify93]

It had happened for me every time I changed the Nothing Happened song to do something, I think.

[Grimoire LD]

I just tested that and changed it to Hold and saw no issues. Hmm, I don't know what could be causing that.

[Pinkpuff]

Did you make any changes to the commands via anything else besides FF4kster (patches, hex editor, etc)?

I had the following command changes done.

Pray: Casts Cure2 upon success, success rate: 70%
Heal: Consumes Cure1 Potions but has a Cure2 Potion effect
Regen: Heals 250 HP every round
Sing: Hold is cast instead of nothing; its message is changed to Message 47. Stop is cast instead of Mute

Sorry. I should've been more concise. I believe it was the description byte that was changed. From the information Grimoire LD gave me for the headered ROM...

"In ROM at...

01EB17 - A9 00 (LDA 00) - Stores message 00 for the first instance of Sing's effects. | I found that this was the description byte. A9 was altered to 2F in this instance.
01EB1C - A9 00 (LDA 00) - Seems to be necessary to change both, otherwise both are considered 00 regardless of what they actually are. | And if memory serves, this is the actual 'spell cast' byte. There was nothing changed here."

  In an otherwise unmodified headered FFII US V1.1 ROM, I just edited Sing's "Nothing happened." song to cast Hold and the Mute song to cast Stop, and A9 at 01EB17, or the "Call on this description for song #1" byte, was changed to 2F. So this change when I edited Project II was definitely not an issue of my own doing, though I must stress it's very easy to fix.

[Grimoire LD]

Hmm, it doesn't seem to be effected by FF4kster, considering that FF4kster wouldn't touch this location as of yet. Are you sure a separate patch didn't effect it in some way?

[vivify93]

If it happened with an unmodified ROM, I'm fairly certain that it isn't anything I did. I could download a fresh v1.1 if you'd like, and test that?

[Grimoire LD]

That could possibly be for the best, since FF4kster shouldn't have a way to change this completely unrelated value that the programmer wasn't aware of at the time.

[LordGarmonde]

I tried it on my 1.1 ROM clean - then after just opening & saving it with FF4kster - and then after actually changing the first Sing call (to Exit). No trouble - used Sing many times random distribution of the 4 choices. I'm sorry to say that it must be your copy of the ROM. Sorry I can't be of more help on that vivify93 - I hope you get it sorted all sorted out.

[vivify93]

It must've been in a previous build of FF4kster, then; I redownloaded FF4kster and made the changes and it's still A9. My problem was fixed easily, actually, I was just worried that this potentially game-ruining problem could've been in a build of the editor.

  Yeah, it was the previous build, apparently. I don't know what caused it, but it doesn't matter since it was fixed. I tested the fresh ROM in the old build, made the Nothing > Hold and Mute > Stop changes, A9 became 2F or whatever erroneous byte it was, I'm too drunk to look it up.

Sorry for raising a ferret-hunt for no reason, but I just wanted to be sure.

[Pinkpuff]

I have a pet theory... 2F is steal evade right? And for a brief period it was being written to the wrong address due to my mistake with the headered/unheadered issue with the Cry offsets. It could be that it just happens that the mistaken address turned out to be Sing's message...

 
It occurs to me though that which messages are displayed by which commands is something that probably should be incorporated into the command editor isn't it ^_^; Is that information already documented?

[Grimoire LD]

That is an interesting theory and one that makes a good deal of sense.

While it is not formally documented it is mentioned in all of my ASM notes. I can grab a quick collection of those (that have them) and post their offsets here.

(In order internally...)

And that should do it!

Also would you like me to rewrite the Kick Options again? I wasn't sure if the last iteration of that was enough to go off of for implementation.[/list]

[Pinkpuff]

Thanks so much!!

If my rephrasing of it was accurate then there's no need, but if something needs to be corrected, then by all means.

[Grimoire LD]

Indeed your rephrasing of it was spot on. By the way, since we have the other four songs here's the means to change the Frog Song into what you like and how it is activated.

Headered Rom

Sing - Song of Toad
- When Inflicted with Certain Status always use Specific Spell rather than a randomized spell.

Caster's Status Byte 1 - 1EB01
Status Determination - 1EB04
Specific Spell - 1EB0D

(Reference for the above -
Status Byte 1 - 8326 (2683)
Status Determination - 20 (Frog)
Specific Spell (19) (Toad)[/list]

[Pinkpuff]

Awesome!

I take it "Inflicted With Certain Status" translates to "if Caster's Status Byte 1 is equal to Status Determination"? (Ideally each variable in the list should appear in the description)
