Compressed files and methods

Hello, I have managed to get the game files and uploaded to AssetStudio to view them, and I found Texture2Ds and Sprites but some of the assets are missing. For an example, there are literally no audio/voice files at all. Then, I noticed AssetStudio doesnt recognize the assets inside a folder called "ondemand" and there are about 2k assets there and I think they are encrypted/compressed. Here is one of the examples of the encrypted assets: Is there a way to decrypt/decompress this type of file? I think those are the remaining assets. If anyone can help me I would really apprecaite it. 5db8fd68-da55-9c4a-c71f-84af76d61103.7z

Hi everyone, I've recently been trying to translate the PS1 game Chou Jikuu Yousai Macross - Ai Oboete Imasu ka (Macross: Do You Remember Love?), but I've found that the game's resource files are all in a compressed format with the extension GKO. I'm not very skilled at handling compressed formats, especially these older ones. The GKO files all start by recording the original filenames before compression, and a single GKO file might contain more than one compressed file. Beyond that, I'm lost. I'm hoping to get help from experts familiar with compression on how to decompress these files. Of course, it would be even better if you could also tell me how to recompr…

Hello, I tried to decompress an UFC 4 .mcd file which has "chunzstd" signature. After removing the 48 bytes header (so the file to start with 28B52FFD) I used quickbms with comtype zstd, at no avail (comtype LZO1Z didn't work, too). Maybe someone can lend a helping hand? comtype zstd set NAME string "" string NAME + "zstd-decompressed.bin" clog NAME 0 0xCB540 0x100000 The 4th parameter for clog is the uncompressed size, where I tried different values (3rd param = compressed size, 2nd: offset into file). (I see, using 48 here instead of 0 I could have spared removing the header...) head_conor_mcgregor_model_CB540-withoutHeader.zip

BACKGROUND INFO The file I am trying to decompress is a large 232MB file titled DATA.BIN file in Def Jam: Vendetta (2003) for the PS2.

How do I decompress CMP files from this game? I need to extract model data. Any help would be great, thanks! cmp.zip

Hi guys! I've been trying to crack the container files from X2: Wolverine's Revenge for quite some time now, but to no avail. They come in a variety of formats, but the main ones are .mdl and .all. These files contain models, textures, animations, and who knows what else. On Xbox and PC, there are also .xpr files (though when opened in a hex editor they appear to be .ypr files?), from what I understand they contain some textures, it would be great to be able to unpack those. The main goal overall is to be able to extract everything that these files contain, primarily the models, and convert them into some common format so that they can be viewed in something lik…

I was trying to decompress this,but I couldn't, they are game character render files, but apparently they are compressed Files Cdbt.zip

Hello everyone, Could someone help me analyze this ITK file from DINO 3? It’s an archive file, and the beginning seems to contain a file directory. However, there are additional ITK files nested within this ITK file, and I’m not sure how to handle this. Furthermore, some of the files inside appear to be compressed. the included Script.itk. When I switch the text encoding to Japanese, I can see fragments of Japanese text. These fragments seem to be compressed, so the Japanese sentences are incomplete, but some words are still recognizable. I will upload some of the ITK files. Since some of them are quite large, I’ve only uploaded a few smaller ones. …

Not sure how to extract the images or audio from these files. It looks like they're encrypted. The game uses Unity and the directory formats are "files\dlc\droid\raw", "files\dlc\droid\ab" and "files\dlc\droid\catalog". The audio files have AFS2 headers, but crash when using the QuickBMS script saying this: Error: impossible to write 0xffffffff2942ffe9 bytes (total 0xffffffff2942ffe9) Check your disk space or the script is wrong Last script line before the error or that produced the error: 27 log "" OFFSET SIZE Attached sample files.

Hi all, I'm trying to extract files from a Konami PSX game. The data is in .R2 archives, which are containers (file count at 0x4). The files inside are compressed. The compressed data starts with the magic string "TEN2". This prevents tools like JPSXDEC from finding resources like TIM images, even though they are listed in the archive header. In the script file (SCRIPT.R2), I can see fragmented, readable text, which suggests the compression might not be very heavy. Does anyone recognize this "TEN2" compression format from old Konami games? I'm looking for any information on the algorithm or a way to decompress the files. Sample files are attached…

Hello I am fan translating NANA from ps2, and so far i have been able to replace the first cutscene by decompiling and recompiling the PSS file that contains the first cutscene. To proceed further I need help disassembling / understanding NKT, NKF files. i assume the NKT is text / texture. NKF is the font files i need for remapping all the SJIS chars into english, and adding missing / needed characters. If anyone could provide me with some dissasemmbly knowledge or a tool on how to decompile / view these files correctly, please contact me @mxlg discord, @mxlgborn telegram. Thank you! here is the cutscene: https://files.catbox.moe/cemfep.mkv

The file doesn't use the regular Kirikiri 2 encryption. It's a data file from a cancelled game. It uses encryption from https://type74.org/ed.php (specifically version 3.4) but I have no idea how to crack it. I tried to decrypt it with xor, but it doesn't seem to use xor. Not sure what encryption it actually uses. Included a second file (ane1177.zip) as a sample of the encryption. data.zip ane1177.zip

Hey guys, how are you? I hope you're well, is it here that people have their minds unlocked in the matrix? 😆 Jokes aside, I'm trying to extract some files from this game: https://www.icarusonline.co.kr/main , and an old game made in CryEngine 3. the file format is .pak or .npk, an old program called PakDecrypt was able to extract files from it just using the RSA Key, but in 2024 the encryption method was changed and since then it is no longer possible to extract files. I would like to know if anyone would be able to figure out what obfuscation method was inserted into the game, you can say below how far I got, but I lack the skills to go further. This …

Hi, the files to this game are encrypted, but I couldn't figure out what algorithm. It's not xor, and I'm not sure how to proceed from here The game uses Unity 2022.2.11f1 2 sample files provided ac.zip

Hello everyone, I have been struggling for some time to extract the assets from the .vfs file in the Steam folder of the game La Pucelle Ragnarok. I am trying to get the sprites of the game since some aren't on spriters-resource.com I tried using Ninjaripper, Renderdoc, Special K and Dragon Unpacker. The later gave results, but I only managed to get sound files. For the pictures, no matter the software, I only get some glitched, negative gray scaled or red scaled ones. My best bet is Quick BMS but I need the good encryption key... I tried this list of keys but the La Pucelle and NIS keys don't work with the Steam version of the game (NIS being the develope…

These are two files with the same suffix that I extracted from the reverse UE4 game pak file. But one of them should have used some kind of compression method. I know I should use the umodel tool to extract it, but umodel does not support saving files for this game. I hope to receive help, thank you! This is a file without compression, I have provided it in the attachment. I can clearly see the file tag ,version,data... This is a file that has been compressed in some way. I can see some data with the same tags and versions as the uncompressed file. The file header contains fixed bytes such as 0x8C06. I'm not sure about the s…

Hello. Included are three archives that, were they uncompressed, I would be able to extract from, being PVR textures. Unfortunately, this kind of thing is well above my head. Help would be appreciated! compressed.zip

Hey, everyone! I recently re-discovered an old game available on the Xbox 360 Live Arcade back in the day called "Hybrid", developed by 5th Cell. I managed to extract the files however textures, models and sounds are compressed and not recognized by any tools. For instance, the .MDL files are compressed with LZMA as far as I could see in the file headers. I will upload a sample of each (sound, model and texture). Best regards! Hybrid_Sample_Files.rar

Hi everyone, I'm running into difficulties with what appears to be a modified GZIP format from a PS2 game(Virtua Cop) and would appreciate some expert help. Inside a container file (CMN.BIN, attached), I found 5 GZIP-compressed . The last four files have standard 1F 8B gzip headers, and I can successfully decompress them using tools like WinRAR to get valid TM2 texture files. The problem lies with the first stream (offset 0x0 to 0x11DF in CMN.BIN, also attached as unknown.bin). Its header starts with 1E 8A. Interestingly, if I add 1 to some bytes in the header starting around offset 0xA (treating FF+1 as 00), I can see what looks like the original filename…
