Very needed decryption

Post by MITA996 »

For two years for now, I'm searhing for complete extraction of fifa online 4. I used aluigi scripts , but It's a bit monoton to search for textures manually, in some big files are around 10,000 dump files. I noticed that korean version and it's algorithm is 64bit block cipher without ivec like blowfish or *tea, but thailand version has a different protection '' Xigncode". Some user said that is based on dictionary and offset... I will post both files, also big files from both versions. A lot of fifa fans or modders will be thankful

Xigncode is an anti-cheat, not a protection setup for files or the game binaries. It offers nothing protective to any of that kind of stuff, just a means to prevent cheating while playing the game.

The Korean version is using a different anti-cheat, from Nexon, called BlackCipher. But neither of these things has to do with texture files.

What you uploaded isn't textures, it's the main game files to run it, which is nothing more than a CEF wrapper for a browser. Does this game have other files holding the actual textures/models or are they all hot-loaded from the web?

The main exe is wrapped with Themida (64bit), so I didn't bother digging into it more than a quick look since I don't have time to boot up my VM and mess with it personally. But from what you uploaded, it doesn't look like any of it is textures at least.

Sure mate, tha actual textures/models are storage in .big files, I can provide you some some scripts that extracting .bigs, also one for decompression. I used file cutter, so there are data 4 big, where are the textures, models and I know that they used here chunkzip compression, data 10 big used chunlzma compression, and in thai_bg I think are main database, but I know db means for database and players id. I didn't know how to extracted it. Here are bigs, and useful scripts, I used file cutter: https://www.mediafire.com/file/gvgpk0zk ... s.rar/file

Not too sure I follow what your issue/desire is then if you can already extract things?
What is your goal here with this?

Seems like you can already extract the big files with that last download.

Yes I can extract big files, but only dump. Every big has it's one folders and sub folders. Extracted data big should have data/sceanessets/faces,hair, heads etc. with players id. Data big 10 should have data/sceanessets/kit. According to players id's you find player. The scripts only provide you dump files and not name files. :(
