Scripting and Reverse Engineering / Re: [FF8] world map and objects (world.fs)

Halfer, excelent work. Will try this on my own.
Oh, by the way- try to completely delete texl.obj file and see what would happen.

Sure, but this can take some time, Halfer is making amazing progress, and after we know how texturing works I could convert data to UV mask only, fix it up and re-parse to FF8.

Edit: I tried to trick game to think I am ragnarok and can pass mountains, sea etc. but no luck. I'll try with coding sea and mountains as grass, thanks to Halfer I know it's possible to do, and where to search.

While coding ultimate hack found this:

Probably GPU related, but it's fun.

I see... Then steam re-release is different than the original one. My first texture is not a water and is at 117720. Hm... I have an idea. Let's see what happens if we mix files between releases.

This is World map with wmsetus.obj with null'ied all textures. 0x1cbd8-0x86cf8 (First file which textures are in center of file, not at the ending)


NOTE: wmsetxx.obj also is responsible for forest walking particle. I have some theory about that ragnarok texture change. Give me a sec, gonna test it.

As I thoughŁ


The textures in wmsetus(sp/it...).obj of world map are for Ragnarok. When you ride ragnarok, the game loads 1/2 sized textures from wmsetus.obj. When you land, the game loads texl.obj file.

TOWNS textures are gone too!

I found it little hard to browse FF8DISC1.img, as almost every extractor for PSOne files is dead. I had to manually extract it. My HexEditor just exploded, so had to work with buffer blockcopy. Thank you Visual Studio. <3

wmx.obj:
FFVIII Steam 2013: A594059C0D6D16F5DBEB8A82C4BE696FEB8A0E3D
FF8DISC1.IMG 0x108800 (size: 0x1D5B000): A594059C0D6D16F5DBEB8A82C4BE696FEB8A0E3D
FF8DISC1.IMG 0x19C8800 (size: 0x1D5B000): 500A79C34243AE19A49078BF36AB156C361F1043
FF8DISC1.IMG 0x388B800 (size: 0x333000): 950BCB3B5C8A3FE7F236C248044EC44653781329

This is a bit confusing. Offset 108800 is the same file that is present in Steam release. I'll run a BinDiff on 0x19C8800 and Steam one.

Update: There is a massive difference in 0x108800 and 0x19C8800 file. See the example:
 
I'll replace Steam wmx.obj with 0x19C8800 dump.

Well. It works. xD But I'm stuck inside some mountain and I can't move. Wait, I'll force ragnarok.

What the...

You're a God Halfer!

It works indeed.


Balamb part is at 1d13000-1d198a0.
Towns and garden is made from triangles and is part of world map, so yes, towns are in wmx.obj.

Also, I'm like 70% sure rail.obj is for trains movement. Deleting file makes train blink sometimes and go crazy on world map. Like show for 1/2 second on center of sea.

@EDIT: I don't know if it's in fact vertex data, probably not, but one byte operates shadow. Probably that unknown data is about shadowing.

I'm currently working on it. Sometimes I need to divide bytes by 256, sometimes by 64 or even 32. I need to find some dependency on it.  This is currently problem number 1.

@up - Okay.

Wmset.obj is using 8BPP and 4BPP textures, with various resolution and CLUT size +  Clut sets. The problem is some 4BPP textures ARE animated / or just are changing textures, or just work as battle stages do. No TIM documentation says about animated sets. I found out, that it's saved as big-endian two bytes before CLUT. Like every byte there is little-endian, but this one is big-endian and should be reordered in code. Really, really weird. This should be calculated like this then:

Code: [Select]

            //Getting # set
            String CLUT_sets = filebuffer[lookuped+16].ToString("X2");
            CLUT_sets = CLUT_sets.Substring(0, 1);

            if (BPP == 8)
            {
                if(int.Parse(CLUT_sets)>1)
                    tempres = tempres + 20 + (int.Parse(CLUT_sets) * 32);
                else
                    tempres = tempres + 20 + (CLUTs * 32);
            }
            else
            {
                if (int.Parse(CLUT_sets) > 1)
                    tempres = tempres + 20 + (int.Parse(CLUT_sets) * 512);
                else
                    tempres = tempres + 20 + (CLUTs * 512);
            }

            tempres += 8; //Padding + origin rot
            UInt16 width = BitConverter.ToUInt16(filebuffer, tempres);
            UInt16 height = BitConverter.ToUInt16(filebuffer, tempres + 2);

First texture is at: 413048 (EDIT: Was 429980, but Balamb uses two times the same texture, and due to file specific it needs to be repeated two times. 413048 is correct entry.)

Texture offset list:
Where: 52 is 1 in index, and 83 is 31 in index.


Could someone please calculate SHA1 from wmset.obj file from 2000PC release? (lang_en).

*HEY! This shot is a bit old and uses 1/2 of texture.

Phew.

World map objects VT calculation:

Code: [Select]

                const float newSzerU = 256.0f; //CHANGE height * 2
                const float newWysok = 256.0f; //CHANGE width * 2

                float UU1 = (float)U1v / newSzerU;
                float VV1 = 1.0f - (V1v / newWysok);
                float UU2 = (float)U2v / newSzerU;
                float VV2 = 1.0f - (V2v / newWysok);
                float UU3 = (float)U3v / newSzerU;
                float VV3 = 1.0f - (V3v / newWysok);
                float UU4 = (float)U4v / newSzerU;
                float VV4 = 1.0f - (V4v / newWysok);
After model there's of course well known: MODULO(Offset)+4
Balamb halo (or ring, whatever you call it) is second model just after Balamb. Ah, can't wait to see what's next.

Train. :3

Any chance for a difficulty mod?
the mods you have done are excellent, But this game is just too easy
// If they had done a training center like the FFX monster arena, where you could get all the additional monsters/boss's
That would've just been amazing
Hopefully if a hard mod comes along, it's so hard that it takes me 500 hours to complete the game

It's not a correct thread nor forum section for this. Please, use IFRIT, that you can find in tools section and read scenes.out specification at wiki and make one yourself. Today it's not that hard, you just follow instructions and read documentation.

No problem. That was fun doing this.
I also found offsets and memory structure for other camera options.


Manipulating camera needs assembly real-time edit. Just changing update functions like ADD/MOV to NOP, and writing to memory blocks at static addresses.

Worked a bit on camera for you. See here:


Technical:

Code: [Select]

FF8_EN.exe+1584EA - add word ptr [FF8_EN.exe+1C3ED00],04
FF8_EN.exe+15848D - mov [FF8_EN.exe+1C3ED00],axAlso Copy memory opcode (MOV) that prevents going down from 65k (2 bytes)

Code: [Select]

FF8_EN.exe+158495 - mov word ptr [FF8_EN.exe+1C3ED00],FE00

Fixed:

Code: [Select]

FF8_EN.exe+1C3ED00 (2 bytes)Fixed memory val works same as Squall X,Y,Z location. This is:
F0 00 is lowest, and FF FF is max. So if I add 00 01 to FF FF, then it's going to be reset to F0 00. But, this is a player location thing. I also found camera real position. Gonna capture now that top-down fragments.


Some notes:

Code: [Select]

FF8_EN.exe+158676 - add [FF8_EN.exe+1C3ED02],ax - LEFT-RIGHT translation (smooth ADD op)
FF8_EN.exe+15871A - add [FF8_EN.exe+1C3ED02],ax - Still ADD, couldn't find MOV
FF8_EN.exe+15873E - add [FF8_EN.exe+1C3ED02],ax - Another ADD
FF8_EN.exe+158948 - mov [ecx+0A],ax - Copy memory! :)
FF8_EN.exe+158936 - mov [ecx+0A],ax - Copy memory, another, ticked only one time, above also

« on: 2015-04-01 20:20:37 »

I real-time debugged process, and found some entries testing on Shiva.

At first, when you summoning G.F. nothing happen to data in memory, it's 00 00... or the state of previous G.F.
After the G.F. gauge runs out, the memory is written by some small data, and after the character animation of summoning passes (You know, that one when for example Squall puts hand from his face to enemy and disappears after) the data is written by .TIM texture. After 1-2 second of Shiva animation, right before she appears in the crystal a data is again written to .TIM texture place and data from mag184_e.dat appears. This is memory dump of this region:
https://www.dropbox.com/s/g2vrrradn7muj8s/MemDump.7z?dl=0

The first texture is broken. Don't know why.

After textures, there's at least 3MB of free space. The models have to be before, but all I can see are still NULL's. At the moment, where there's ice over enemies, and shiva is no more able to be seen, the data is again overwritten. That's the real problem. I can't help myself with real-time memory edit/debugging if the values and addresses are changing by the situation.
