Thanks, glad it's working. It's been so long since I've worked with it I doubt I could even answer any questions about the code anyway.  :wink:

Final Fantasy IV Research & Development / Shadowing Stat Data
« on: April 09, 2011, 11:04:16 AM »
At the request of Zozma, I finally found my original documentation on shadowing stat data. I've attached the text description with the hex data to paste at various offsets (FF2us v1.0 headered ROM), as well as an IPS patch that I *think* is complete. (Although it might be for my own hack, which means you might have some non-standard data.) This will should properly copy shadow data for all characters when you add or remove them.

Real life has taken over, so I don't have much time for hacking any more, and probably won't be able to answer questions about any of it. Hopefully you guys can figure it out!

No, I've been too busy with work for the last few months to even touch anything to do with hacking. Someday I might revamp it, but it'll be a long way off.

Hey, thanks for the compliments! I've been swamped with work lately, so I haven't been able to work on my hack much, but you make me want to get back to it. Here's hoping that I'll get some time soon!

I don't have time to search through the list, but I'll post my Events list again if you want to look through it. I don't list Rydia in every event she learns the spell, but I'm sure you know the events well enough that you should know when she learns it and can figure it out.

The red template is broken in the new version. There isn't enough space between items, making things shift to the right. Also, the "New Posts" and "No New Posts" icons aren't working on the front page.

Cheers!  :happy:

Dragonsbrethren, your link doesn't work -- they have hotlinking disabled.

The Leviathan event loads at (A8, 90), which is exactly where that map has it posted: just a bit southeast of the Kaipo desert.

Fun to watch . . . but I'm sure not so fun to play. It looks like another good idea that wasn't executed very well.

In other news, I started up my hack again last night, after a four month break of being too busy. I'm hoping to have it finished by November (which would be three years from when I started hacking FF4). I'll keep you guys posted.

For the location triggers, there's something I don't understand about the way they call events.

From what I understand from the doc posted by Phoenix, there are five bytes to each location trigger. The first two are the (x, y) co-ordinates of the trigger on the corresponding map. That much is easy enough to understand. Then, if the third byte is FF, it means the trigger is an event call (as opposed to being a chest or a teleporter), and the next byte is the event that will be executed. However, looking at the actual data, it must be more complicated than that.

What I mean is, if for example you look at the trigger in the Mist Village that is supposed to execute the event where the bombring activates, the code is:

Code: [Select]
08 10 FF 0C 00
I took that to mean "When the player steps on the tile at (8, 16), execute event number 12." However, event number 12 [0C] is the message "Empty."; the bombring event should be event 48 [30].

So I guess what I'm asking is, is there some table somewhere that the "0C" is indexing? And if so where?

Thanks

Sorry, another piece of information I forgot!

Code: [Select]
97460-9765F Event Trigger Pointers (tells which event each FF Location Trigger invokes, reverse and add 0x97660)
97660-9785F Event Trigger Data

The event trigger data is formatted like the NPC speech data. So basically, that "FF 0C" points to event trigger 0C, which has a series of conditionals and event calls (or just one event call, depending). My event trigger document isn't very long, so I'll just post it here (it has all the data broken down by line, which is useful):

Code: [Select]
======================================================================================
Event Triggers Phoenix Hacks
12/22/09

======================================================================================

Map tile triggers reference event triggers. The pointers for these triggers are
located from 97460 to 9765F. To find where these point, reverse the bytes and
add 0x97660. The event trigger data is located from 97660 to 9785F.

======================================================================================
FFxx = Load event xx
FEaa = If event flag aa is set...
aa = If event flag aa is clear...

Examples:
aaFFxxFFyy = If event flag aa is clear, then load event xx, else load event yy
FEaabbFFxxFEccFFyyFFzz = If event flag aa is set and bb is clear, then load event xx,
else if event flag cc is set, load event yy, else load event zz

The event trigger data, like the NPC speech data, utilizes events numbers 01-03,
which are EE message calls: "Show message [hex data xx following event call] (from bank 2)"
For example, the Old Man wandering in the town of Baron has the following data (at 99EDE-99EEA):
FE 06 FF 03 FE 0B FF 02 FF 01 03 04 05
This translates to:
Data Meaning
-------- ------------------------
FE 06 If event flag 06 is set,
FF 03 load event 03 (i.e. message call EE 02 = message 05 of bank 2)
FE 0B (else) if event flag 0B is set,
FF 02 load event 02 (i.e. message call EE 01 = message 04 of bank 2)
FF 01 (else) load event 01 (i.e. message call EE 00 = message 03 of bank 2)
03 04 05 [Hex data following event call]
======================================================================================

You'd think that ninth tile would work, but it doesn't. If you look at all the characters' "special" sprites, none of them use that ninth tile. You'd probably have to change the graphics loading routine to make it work, but I don't know where that's located.

can i steal that info(and the info posted above), phoenix, along with those text documents you posted a few days ago?  i'm going to sit down for a couple hours next weekend and add all the new info i can find to the archive site.  i finally got some decent hosting(read: loads of space and bandwidth), too, so it's at rb.thundaga.com now.
Feel free. Once I finish my hack I'm going to clean up all my documentation and make more sense of it. But for now, you can take whatever I post and use it for whatever you want.

Hmm... I noticed in Zyrthofar's beta editor, that in those four bytes there's quite a bit controlled. The location of course, I'm guessing it looks at that other list for Sprite Number, but here it has Walking Event, Event turns when spoken to, Walking Animation, Can Walk Through (1), Can Walk Through (2) and 3 unknown bits. You pointed me towards the NPC Palette, so I don't think that's very important and direction, now I am to guess this is readily available info. if a viewer has it, only problem is, I'm not sure where that info is.
Did you check out the NPC Placement document? That has all the information on what the bits of those 4 bytes mean. I'll put it here again (in case anyone doesn't want to download the zip file):

Code: [Select]
Byte 0: NPC
Byte 1:
bits 0-4: Starting X position
bit 5: ? (permanently deactivates NPC)
bit 6: ?
bit 7: The NPC walks
Byte 2:
bits 0-4: Starting Y position
bit 5: ? (permanently deactivates NPC)
bits 6/7: Characters can walk through the NPC
Byte 3:
bits 0-1: Direction the NPC faces
00: up
01: right
10: down
11: left
bits 2-3: Palette
bit 4: NPC turns when spoken to
bit 5: NPC moves in place even if not walking
bits 6-7: Movement speed

Yes, I didn't think about it, but the town tileset probably isn't set to load encounters by default. You'll need to edit the tile properties. Here's the info:

Code: [Select]
Location Map Tile Properties are located from A1000 to A1FFF.
Tiles are 2 bytes each, using the following format:

Byte 0:
bit 0: Layer 1
bit 1: Layer 2
bit 2: Same layer on opposite side (Transition or Bridge Layer)
bit 3: ?
bit 4: Closed door tile
bits 5-7: ?
Byte 1:
bits 0-2: ?
bit 3: Bottom half is in front of the character
bit 4: Load previous map at previous location (Location Trigger)
bit 5: ?
bit 6: Enemy encounters possible
bit 7: Check tile’s location in [Location Trigger Data]

Change bit 6 of the second byte to 1 to enable enemy encounters. For instance, the town tileset starts at A1400. The first tile there is 0100 (so the second byte in binary is 00000000). If you wanted encounters on this tile, you would change it to 0140 (second byte in binary: 01000000). Hopefully that should be the last piece of information you need.

Sorry, I forgot about the encounters. To edit those, you'll need three bits of information:

Code: [Select]
74500-74741 Probability of Enemy Encounter (byte/FF % chance)
74500-7453F For the Overworld (1 byte per 32x32 tile region)
74540 For the Underground (1 byte for the entire map)
74541 For the Moon (1 byte for the entire map)
74542-74741 For Locations (1 byte per location)
74742-74995 Enemy Encounter Indexes (reference the Enemy Encounter Tables)
74742-74781 For the Overworld (1 byte per 32x32 tile region)
74782-74791 For the Underground (1 byte per 32x32 tile region)
74792-74795 For the Moon (1 byte per 32x32 tile region)
74796-74995 For Locations (1 byte per location)
74996-74A15 Enemy Encounter Table for World Maps (1 byte per enemy set, 8 possible enemy sets per entry)
74A16-74C95 Enemy Encounter Table for Locations (1 byte per enemy set, 8 possible enemy sets per entry)

You can leave the Encounter Tables as is (unless you want to change possible enemy sets up), all you'd need to do is edit the Probability from 00 and change the Encounter Index to whichever enemy sets you wanted.

All the info on NPCs is in the documentation in the file. You'll have to hex edit the data yourself to change which NPCs appear where. For example, the NPC Placement data in Tomra is:

Code: [Select]
Offset: 9918B
1D 8F 15 BA
01 93 0E 7B
02 84 17 F8
03 8C 05 39
04 9B 17 39
05 9C 16 BA
00
This means that it uses NPCs 1D, 01, 02, 03, 04, and 05 of the Underground/Moon set (take a look at the NPCs document to find out which sprites and speech data these NPCs use). Probably the easiest to do is edit the sprite value and speech data of these NPCs.

Exits (like treasure chests) are also triggers. Take a look at that document. You'll have to change the (x,y) coordinates of the exit triggers to line up with the trigger tiles (the ones with the red dots or arrows).

I've gathered a little more information on the map properties (or map headers), so I'll reiterate it here:

Code: [Select]
================================================
Location Properties (A9E84-AB203) 13 bytes each
================================================
00: Battle/Spell Properties
bits 0-3: Battle Background
0: Grass 8: Magnes/Sealed Cave

3: Castle B: Land of Monsters/Sylphs
4: Cave C: Tower of Zot
5: Moon D: Lunar Subterrane
6: Ship E: Crystal Room
7: Water F: Underground
bit 4: Warp can be cast
bit 5: Exit can be cast
bit 6: Use alternate palette if available (backgrounds 0, 4, 7, 8, B, C)

etc.

bit 1: Vertical Background Relative Movement
bit 2: Horizontal Background Relative Movement
bit 3: ?
bits 4-5: Direction
00: Up
01: Right
10: Down
11: Left
bit 6-7: Speed (Absolute Movement / Relative Movement)
00: None / None
01: Slow / Moves slowly in character's direction
10: Medium / Moves in character's direction
11: Fast / Moves opposite to character's direction
0A: Map Set From Which to Load
01: Load map from Underground/Moon set
80: Load NPCs from Underground/Moon set
0B: Map Name Index
0C: Treasure Contents Index

I'm working on adding loading the tilesets from the ROM and being able to choose the palette and some other map properties, so you'll be able to do that in the next release.

One thing you should note: if you're loading this map directly from the Overworld, you won't be able to use Tomra's map, since the index for it is in the Underground/Moon set. You could load it from another location map (because the triggers have the ability to do that) but the Overworld triggers don't. Good luck.
