I'm trying my best to make it load somehow

Actually the LZSS provide above, is wrong, for the files. I did the reverse enginner of the algorithim, Try the tool, see if the image get right TenchuWoH_DeCompressor.zip

There is the tool PS2JunjouUnpacker-decompressor.zip

I've just released new version of ImageHeat 🙂 https://github.com/bartlomiejduda/ImageHeat/releases/tag/v0.39.1 Changelog: - Added new Nintendo Switch unswizzle modes (2_16 and 4_16) - Added support for PSP_DXT1/PSP_DXT3/PSP_DXT5/BGR5A3 pixel formats - Fixed issue with unswizzling 4-bit GameCube/WII textures - Added support for hex offsets (thanks to @MrIkso ) - Moved image rendering logic to new thread (thanks to @MrIkso ) - Added Ukrainian language (thanks to @MrIkso ) - Added support for LZ4 block decompression - Added Portuguese Brazillian language (thanks to @lobonintendista ) - Fixed ALPHA_16X decoding - Adjusted GRAY4/GRAY8 naming - Added support section in readme file

The textures are compressed with ZSTD - just that type 0 means the whole file is not compressed. But there doesn't seem to be any encryption once decompressed - looks something like ETC format:

Thanks for some info from here and made a tool for unpacking and packing localize map files, if someone is interested in it. https://github.com/dest1yo/wwm_utils

It's been a while since this topic is up and i have found a way to deal with this: -Step 1: From the .farc files, use either the tool mentioned at the first post of this thread, or download QuickBMS and use the virtua_fighter_5 bms script i included in the zip file below to extract them into bin files. -Step 2: Download noesis and install the noesis-project-diva plugin (https://github.com/h-kidd/noesis-project-diva/tree/main , or in the included zip file) in order to view and extract the textures/models and use them in Blender or a 3d modeling software of your choice.

When debugging function 0010D850, I found these filenames in the t0 register (after the decryption result; it also loads the filenames of files with the .JRS header into memory): LOGO.JRS MAINSCRIPT.JRS SCENARIO.JRS SCENARIO00_ROMA.JRS SCENARIO00_ROMA_TGS.JRS SCENARIO00_ROMA_TRIAL.JRS SCENARIO01_EGOI.JRS SCENARIO01_EGOI_TGS.JRS RES/SCRIPT RES/SCRIPT/SC RES/SCRIPT/SC/00_ROMA RES/SCRIPT/SC/01_EGOI RES/SCRIPT/SC/02_TERO RES/SCRIPT/SC/10_KAISOU SCRIPT.SVL etc... The flow is: SCRIPT.PTD (disk) → [AT GAME STARTUP] → Decompress YKLZ → Decrypt .JRS → Load into PS2 memory --- Knowing this, I set a read/write/change breakpoint in the PS2 debugger after the initial file-loading process in RAM. In this case, I set it at 0056AC20 (which corresponds to `SCENARIO00_ROMA.JRS`), and as expected, this is the first dialogue shown in the Romantica route. 0011A010 (game_load_resource) ↓ 0010DED0 (file_system_wrapper) ↓ 0010DB58 (process_filename) → Converts "SCENARIO00_ROMA.JRS" to something ↓ 0010DC48 (binary_search) → Searches table using 0018E4FC (optimized strcmp) ↓ 0010DD98 (get_file_info) → Returns data_ptr (already in memory?) ↓ RETURNS to 0011A010 ↓ ...... 00106800 (PROCESS .JRS?) → UNKNOWN ↓ 001068D0 (FINISHES?) → Another unknown --- FUNCTIONS 0010DC48 – Binary Search - Searches for files in a master table sorted alphabetically (only to verify file calls are correct) 0010DD98– Get File Info - Returns data_ptr (already in memory), size, and flags 0010DED0 – File System Wrapper - Orchestrates the search and retrieval process 0011A010 – Game Resource Loader - Manages memory pool - Calls the entire system --- The only thing left to do is trace the flow and see what gets called after the .JRS file is loaded (which is obviously to process and render the text). With the information on how the game processes and displays text, we can process the previously extracted files from script.ptd to view the Japanese dialogues. I need to rest my brain… haha

There is a "thanks button" (just in case you didn't know).

animewwise just closes instantly if you try it on there. Regular wwise works https://github.com/mortalis13/Wwise-Unpacker BeyondToolsMod-net9.zip

Yeah if you are fan of defining almost 800 resource types then go for it. I have faith in you...

This is the font game uses.

1. FILE STRUCTURE (script.ptd) | Offset | Size | Content | |--------|------|---------| | `0x00` | 32 bytes | **Header** with signature "PETA" (50 45 54 41) | | `0x20` | 256 bytes | **SBOX** (Substitution Box for decryption) | | `0x120` | 1,728,224 bytes | **Encrypted data** | 2. DECRYPTION & DECOMPRESSION PROCESS script.ptd → Decryption → YKLZ/LZSS → Binary Script 249 YKLZ/LZSS compressed sections found in decrypted data YKLZ/LZSS decompression works correctly 3. DECOMPRESSED SCRIPT ANALYSIS Header identified: `純ﾛﾏ = "JUNROMAN" Current issue:Shift-JIS Japanese text not found - appears encrypted even after decompression Example decompressed output: 純ﾛﾏ####@###ｼg##@###ﾄ###4.##X)##ｲ*##4... 4. SUSPECTED SCRIPT STRUCTURE?? [Shift-JIS Text] [Padding "####"] [Command "@" + 3 params] [More Text]... Parsing logic??? 1. Parser detects `@` (0x40) → Command indicator? 2. Reads next 3 bytes → Command parameters? 3. Processes Shift-JIS text (1-2 byte characters)? 4. Skips padding `#` (0x23) → Alignment bytes 5. GAME EXECUTION FLOW (pcsx2 debugger) fcn.0010e048 (Interpreter) ↓ fcn.0010ded0 (Parser) ↓ fcn.00119fc0 / fcn.0011a0ec (Handles dialogues?) ↓ fcn.00106800 (Context configuration) ↓ fcn.001068d0 (Text rendering) ↓ fcn.0016e400 / fcn.0016e4a8 (Unknown final processing) 6. CURRENT PROBLEM The text appears garbled/encrypted even after YKLZ decompression....... Additional encryption layer** after LZSS decompression??

Please don't publish tutorials until you finish them. Also, Raw Texture Cooker is outdated. It's better to use ImageHeat https://github.com/bartlomiejduda/ImageHeat It supports more pixel formats etc.

Today I am gonna discuss on how we can reverse engineer the extraction of the game archives, sit back because this is where it starts to get interesting... +==== TUTORIAL SECTION ====+ But how do those files store game assets like 3D Models, Textures, Sounds, Videos and etc... Well, the anwser is simple, they usually bundle them, they pack them close together in their eighter compressed or even encrypted form (Rarely). To understand let's first quickly move into the basics, into how the Computer stores any file at all. DATA TYPES Those are the most frequent Data types: Byte/Character = 1 Byte, so 8 Bits Word/Short = 2 Bytes, so 16 Bits Dword/Int = 4 Bytes, so 32 Bits ULONG32/Long = 4 Bytes, so 32 Bits ULONG64/Long Long = 8 Bytes, so 64 Bits Float = 4 Byte, so 32 bits Double = 8 Bytes, so 64 Bits String = A sequence of 1 Byte Characters terminated with null ("00") Where Bit is literally one of the smallest Data that we can present, it's eighter 0 or 1 but combining those 8 Bits together (Example: 0 1 1 1 0 0 1 1) so we get a whole byte. So, all files literally look like this: Addres: HEX: ASCII: 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F 0x00000040 2a 2a 20 2a 2f 0a 09 54 61 62 6c 65 20 77 69 74 ** */..Table wit 0x00000050 68 20 54 41 42 73 20 28 30 39 29 0a 09 31 09 09 h TABs (09)..1.. 0x00000060 32 09 09 33 0a 09 33 2e 31 34 09 36 2e 32 38 09 2..3..3.14.6.28. 0x00000070 39 2e 34 32 0a 9.42. This is called a Hex dump, it's essentially a mkore human readable code of binary file that aside the actual Binary data in HEX shows us the Adresses and the ASCII representation for each 0x..0 to 0x..F line. The packed file usually contains compressed data and a small separator/padding between them, hover it doesn't tell us the name and the path of the file we want to com press, whch is a problem. Heck, we don't even know which compression method was used and which "flavour/version" and how the decompressed file should look like... That's where QuckBMS comes to help. QuickBMS QuickBMS has one very specific function I wanna talk about, it's "comptype unzip_dynamic" it supports millions methods and their "flavours/versions". It has also a very fast perfomance and is good for extracting the multiple files out of the package at once. There are also already lots of QuckBMS scripts out there for extracting specific archives, but I'll talk about that later. Compression types As said previously, the block separators/markers are very usefull to identify but turns out most of the compression methods have their own headers and magic numbers, here are few of them: Magic numbers: ZLIB: 78 01 (NoComp) 78 5E (Fastest) 78 9C (Default) 78 DA (Maximum) LZ4: [No Magic Numbers] LZ4 Frame: 04 22 4D 18 (Default) LZW: [No Magic Numbers] LZO: [No Magic Numbers] BZIP/BZIP2: 42 5A 68 GZIP: 1F 8B 08 Practical steps Below is the example of how average QuickBMS Archive extractor looks like, it's also one of my first favourites and the first one, it's designed for extraction of assets from Wolfenstein: The New Order & Wolfenstein: The Old Blood: wolfenstein.bms: open FDDE index 0 open FDDE resources 1 comtype unzip_dynamic endian big goto 0x24 get files long get unk long math TMP = files math TMP - 1 for i = 0 < files endian little get FNsize1 long getdstring FN1 FNsize1 get FNsize2 long getdstring FN2 FNsize2 get namesize long getdstring name namesize endian big get offset long get size long get zsize long get unksize long math unksize * 0x18 math unksize + 5 getdstring unkdata unksize if size = zsize log name offset size 1 else clog name offset zsize size 1 endif if i != TMP get filenumber long endif next i Script summary: Open index + data files Read file count For each file: Read filename Read offset and sizes Skip metadata Extract raw or compressed data Compression logic ConditionAction | size == zsizeRaw copy | | size != zsizeZlib decompress | In ID Tech 5, games have all assets packed inside the .resources files and all of the metadata like name, path, extension, compressed size, decompressed size are in the .index files that means is that we open both files in this way: 1. Setup open FDDE index 0 open FDDE resources 1 open = tells QuickBMS to open files. FDDE = the format ID (arbitrary, just a label). index -> is opened as file 0 resources -> is opened as file 1 comtype unzip_dynamic 2. Loop This sets compression to Zlib dynamic (handles soo many decompressions). endian big This sets reading data in Big-Endian. goto 0x24 Jumps to 0x24 to skip archive header get files long get unk long files -> total number of files in the archive unk -> unknown value (probably versioning or flags) math TMP = files math TMP - 1 TMP = holds files - 1 (Used later to avoid reading an extra value after the last entry). for i = 0 < files The script now iterates once per file entry. endian little The filename block is little-endian, even though the rest of the archive is big-endian. get FNsize1 long getdstring FN1 FNsize1 Reads length of string Reads string data get FNsize2 long getdstring FN2 FNsize2 Another string component get namesize long getdstring name namesize This is the real filename name is used later by log / clog This determines the extracted file name on disk endian big Switch back to big-endian. get offset long get size long get zsize long offset = Where the file data is located in resources size = Uncompressed size zsize = Compressed size get unksize long math unksize * 0x18 math unksize + 5 getdstring unkdata unksize Reads a count (unksize) Multiplies it by 0x18 (24 bytes per entry) Adds 5 extra bytes Skips a block of unknown metadata This is not used for extraction, only skipped to reach the next file entry. 3. Extract the files if size = zsize log name offset size 1 If compressed size equals uncompressed size: File is stored raw log copies data directly from file 1 (resources) else clog name offset zsize size 1 endif clog means compressed log Reads zsize bytes Decompresses using unzip_dynamic Writes size bytes to disk if i != TMP get filenumber long endif Between entries, there is an extra long Probably an ID or index value Not present after the last entry This prevents reading past the table next i Repeats until all files are extracted

My first try on this .lwo format.

Skeleton deformations for the character creator is probably a more accurate term for Veilguards “morph targets” (DAO/DA2 use straight up targets while I/VG use the skeleton to deform morphs with different bone positions) But I’m not a game dev. 😉

You could check the MakeH2O_log.txt. If you find a structure like 12 4 4 4 4 4 (for example) the last "4 bytes block" might be alpha uvs (just a wild guess). edit: it's 16 8 8 4 4 here Try using 82ea3, 4 for uvs. Looks promising.

I've been trying to work on Jon Jones hair (beard) file and was able to export it with the beard diffuse UV, but I'm struggling to get the proper UV for the alpha texture. Any suggestions? hair_jon_jones_model.mcd(decompressed).7z

I think you've already set up the aes-key and the correct version of Octopath Traveler 0 (5.4) on fmodel. You need to add the usmap file, which I attached. To do this, go to Settings->Mapping File Path and select the game's usmap file. Then, in Fmodel, navigate to the correct folder (e.g., Content/Local/DataBase/GameText/Localize/EN-US/SystemText/GameTextUI.uasset) and export the file to .json, with right-click and then Save properties (.json).

The script has been updated and is now output in Lua format whenever possible. format_hotfix_data.py

here you go : 0x09D01B34E843AC6BE08BD854B3CEDA0C4CA52281C08B02BF827F3ADA77173BCA

Yeah, the DWord face indices totally don't fit but I have a déjà vue of this picture, maybe on former Xentax? edit: correct vertex start is 0x144

ImageHeat v0.39.2 (HOTFIX) https://github.com/bartlomiejduda/ImageHeat/releases/tag/v0.39.2 Changes: - Fixed hex input - Changed endianess and pixel formats bindings (required for hex input fix)

So here's pixel format for ps4. PF_DXT5 = 7 PF_DXT1 = 13 PF_BC7U = 22 PF_UNKNOWN = 2 not sure but can be RGBA

This file stores luac and dat data, so it cannot be processed using the unityfs split script. I wrote a new split script to experimentally disassemble the file content you provided and decompile the lua file. If you want to decompile please enable the -j parameter Basic usage (no decompilation) python pkg.py input.patch output_dir With decompilation (slower) python pkg.py input.patch output_dir -j For decompilation, please download unluac from other locations. After compilation, place the .jar file in the same directory as the script. Due to different compilation environments, errors may occur, so unluac needs to be compiled by yourself. pkg.py

I remember to make a request in your github about it. 👍 Somehow, we were not able to see these textures in ImageHeat, only after extraction and decompression. Anyway, for the Switch textures it seems to be an issue as h3x3r said above and I confirm it too. In the attachment you find all the textures in UNIFORM.TEX (including jersey-color) from the Switch version already decompressed. The stock texture file is in the Switch files in the first post (UNIFORM.TEX). In the screenshot below you see the parameters for the jersey-color texture. Maybe useful when you have time to check it to help you fix ImageHeat. UNIFORM Switch decompressed.zip

Nobody's making fun of you. However, it would have been useful if you had mentioned not having a computer at the start, instead of having people waste their time on things you can't use. It also sounds like you were harassing another user in DMs for help, which you also need to stop doing. People will help if they want to, and if they have the time.

You need to decompress them first. Only then you can succeed... Here's jersey-color after decompression. PS4 format. But there's problem with switch format. ImageHeat doesn't support swizzle format. But RawTex can handle this.

I've moved this topic to graphic file formats, rather than 3d Models where you posted it. Also, please don't start another post for the exact same thing. I've deleted your other post as a duplicate. Please read the rules before posting again.

fmt_FGOArcade_mot.py Still incomplete

I used the file "tex_DeadSpaceMobile.py" from this GitHub link provided by Sleepyzay Here is the link Sleepyzay mentioned adding the script to the repository in a later post. When you have the file, just add it to the folder "noesisv4474\plugins\python" and you should be good to extract the textures after restarting Noesis or pressing "Reload Plugins" in the "Tools" category on the hotbar.

tool.py Here a working script that will output json file with { hash: text, ... }

I made a blender addon to import models, textures and animations for dolphin wave and other games that used the same engine. it can import lzs and lza files as is. You don't need to decrypt or decompress the files https://github.com/Al-Hydra/blenderBUM

To whoever ends up here in the future, there is a really simple to use utility to convert files from Xbox ADPCM to PCM and vice-versa on Github: Sergeanur/XboxADPCM Thanks for the thread, I really thought the WAV files I had were lost forever due to an obsolete codec..! In my case, I am porting the PT-BR voiceover of Max Payne from PC to Xbox, which I am surprised wasn't done before.

I found the solution. Use the pak.py python script (i uploaded) in the same directory as the .data file This will extract the UE4 .pak file from the .data file Since the version is 4.27, use the QuickBMS 4.27 Unreal Engine Script to extract all data!

Hello Ikskoks! Thank for the solution. I have seen most of your links long ago but because it says nothing about the "mysterious bytes" after the string "grid", I fall in the conclusion that SOL Files isn't documentation enough. Crazy though, I wouldn't care about where the AMF format bytes data is, as long as the script reproduces a SOL file format and work on the Flash game in question is what matter, like I did with DS-nitro-files-builder. Regardless, this is clearer now. So, there are SOL Editors. My Python project is useless!

by the way if you need names of audio files put thesescript.zip in AetherGazerLauncher\AetherGazer\AetherGazer_Data\StreamingAssets\Windows folder , run process.py then it will change every audio .ys files to proper names.

rename it to .awb files then use the lastest vgmstream, works well

They are still pck files. I can find many wwise .bnk files in AA462ABBFEC319B665666E14585F97D9_EndfieldBeta with ravioli explorer , RavioliGameTools_v2.10.zip (if you need)and I think quickbms also work. By the way I guess the really wem audio files are in another pck files. there are over 5000 bnk files in AA462ABBFEC319B665666E14585F97D9_EndfieldBeta. That means the bnk files may not store any actual audio files

For this format it's not as hard as you may think of. It's just a matter of persistent search which some people lack of and leave it to guys like me... Be that as it may, here's a H2O example, copy the 6 lines into notepad, for example, and save as ch0001_01_whatever. Rename the .txt file to .H2O then and load the model and the H2O file into hex2obj. Press the 'mesh' button. 0x951408 11085 Vb1 32 99 0x8F8A68 5239 021010 0x0 255 ch0001_01 obj.bin seems to contain different meshes: And the start address of the concerning FI block is unknown: Being bored by this annoying FIs' start address search for each sub mesh I used meshlab again:

use my plugin for Noesis arc_zlib_plzp_lang_vfs.py (which I mentioned earlier) it recursively unpacks all files, at the output you will get *.png, *.wav, *.pm3, *.vram, *.text, *.pvr and e.t.c You can also find a link to the plugin for 3D models *.vram above in the same topic. (*.pvr can open in PVRTexTool)

zlib_DeCompressor.pyHere the DeCompressor update, now works with every file

The WAVE files just use XBox ADPCM (not that obscure) and you can play and convert them with Foobar + vgmstream (note: some files don't contain audio). You don't really need to do anything else.
