Does anyone know of any data relating to spell effects besides what's at 799A0-79F9F (headered, 6 bytes each)? I tried changing some of the spells, but there seems to be some hardcoding (or other data) affecting them. For example, try copying the data for Life2 (located at 79A18) to Life1 (located at 79A12). When I did this, the new spell still acted like Life1, and would revive but not do a full HP restore. So, there must be something else affecting it, but I can't find where. Any ideas where to look?

Does anyone know of a way to expand the palettes in FF2us? From what I can tell, the world map has 3 colors per sprite, and that won't work for what I have in mind.

I'd be curious to know if there is a pointer and "amount" ASM code that would be able to be expanded and repointed. DKK?

For expansion you mean improving the palettes to use 16 colors instead of 8? I can say that wonderfully works for portraits, not sure about the rest of the game. :blush: (http://i239.photobucket.com/albums/ff233/Geminimewtwo/Final%20Fantasy%20IV/magic.png) The effect is pretty cool with FF4A portraits.
Palettes are loaded using a simple MVN, while portraits are copied and converted to vram using dma writes to $2118 and $2119 (same goes for the cursor, that's why my picture has it corrupted).

Gemini, could you post more details about what to change and where it's located in the ROM? That's a neat result, and something I hadn't considered changing until just now.

Well, I can tell you more or less what to change in the Snes version (the image refers to the Psx porting), but I'm not 100% sure it will work that way. Code was traced from FF2us, but it might be stored at the same offsets in any Snes version.
LDA $0000,y STA $18 LDA $0001,y STA $19 INY INY The attached package contains an almost complete set of GBA portraits already converted for the Snes. 0~1DF is palette data, everything else is portrait data. Frog, pig and minimum images are missing, but I will probably add them someday.

That is really awesome, I wanted to look into upgrading the graphics to 4BPP myself but wasn't sure where to start, now I have an idea of how to go about doing that.

Wow.
As my first post around here I'd like to say that finding this forum has been awesome.
And second, of course on topic, is how cool hacking the 16bit GBA avatars into the game is. That mod rules.
I've been slowly working on my own hacks and have wanted to upgrade the graphics of the original SFC FF-IV version for a while. I've modded some town tiles a little bit by tweaking them within the original 3bpp graphics and 8 color palettes... But nothing this cool.
Now I know I need to get into the ASM side of this "hobby"...

It's about time someone improved the graphics. :wink:
Are there things that have yet to be document battle-wise? I think I've about covered it all (I could be wrong but meh).

I don;t know exactly the details, but you have to change the spell attributes as well for targetting, power, ??, effect1, effect 2, MpUsed(& Wall ignored). Also there's a 4 byte number reffering to graphic color pallete, graphics 1, graphic 2, graphic 3. Finally there's an extra byte for the "sound effects" the spell will make. Example, change the White spell to a Holy colored Nuke type spell, change the the sound effect from there pearl overcast to the nuke sound and the graphics like: Name Graphic Sound-v Nuke = 0C 04 24 21 & 6A ; Holy = 06 04 24 21 & 6A Life1 = 15 02 1F 00 & 27; Life2 = 15 02 20 00 & 27 ^size type
I read everthing in hexadecimal and read it like a book.

I know about the graphic/animation bytes and the sound effect byte. Changing them doesn't affect what I was talking about, though. Try replacing the Life1 effect data (the six bytes) with the Life2 effect data, and then casting it in battle. You'll find that even the same effect data doesn't do a complete HP restore, it still only revives. So there's something else going on.
Edit: Sorry, no MP restore...I knew that, I don't know why my hands typed that... :eek:

Life2 doesn't do any sort of MP restore.

Infact it really needs to cost more MP to cast to begin with. *feels evil* :banonsmash:

I don;t know where the negative MP effect would. But it could posibly be reprogramed to take away -MP instead of +MP, but I don't know yet if the values could be signed that way.
I tried.. I still have lots to find. I'm reading and editting the rom via thingy32(v0.19), and I'm enjoying reading the HexaDecimals.

have you tried changing the second byte(spell power) to max? (7F o r FF)

Yes, changing the spell's power to FF results in a super-powered spell. There are two enemy spells that have a spell power of FF: the CPU's Globe199 (which is why it can consistently do 9999 damage) and Bahamut's MegaNuke. For spells like Stop or Wall, it lengthens the duration of the status effect. For Slow and Haste the most significant bit determines a positive or negative speed change, and the rest of the number determines by how much.

That bit is definately interesting. One could theoretically create several levels of one of those spells like the3 "Stop" items. Imagine a 3 level Slow or Stop in the magic list?
