Hi, if you PM me the file I'll have a look at it, thanks.

Thanks for info and research. Could you please upload binary with movie extraction support? If not on GH, then here. Thanks in advance!

I already linked it a few posts above, but here it is again

Edit2: EBP did turn out to be the current iteration of the function so that is what gets blended with the result of the murmurhash func, the rest is pretty much the same and that's all there is to the movie decryption. I've added an implementation of it to the tool I posted above.

Any progress on exctracting videos from movies.mpk file? The decryption used on the mpk files is the same for the header and info, the salt is different this time { 0x833237C3, 0xBA5CD4B6, 0x3371A06B, 0xAEA7EDB2 }; 0x04 of header is the 4 bytes which replace the first 4 bytes of the salt this time ...

Looking into it more, it looks as if that other decryption path is hit once it starts reading above 0x80000000 (for example once the compressed offset is above that)
EDIT: Nevermind, false alarm. Was just an fseek problem.

Thanks for the work you two have been doing on decryption, and for keeping things open as well. I've updated an old repo I had based on your findings. I didn't implement that new information about unaligned data, but some things seem to be decrypting correctly. file 0 of 7017f9bb9d52fc1c4433599203cc...

Here you go;

https://github.com/Jayveer/SOR4TEX/releases/tag/1.0

you have to run it from the command line like so;

SOR4TEX textures texture_table

As it creates directories it may need cmd to be run as admin.

Right. But my point is don't be mad at those that have created the jailbreak it's understandable why they wouldn't want to release the method (because Sony would just patch it if they knew how it worked). I can see your point about the person posting pictures of the model, especially considering the...

There is a secret jailbreak, you're not understanding what I'm saying. Working with a games files (converting models etc) is not the same as decrypting a PS4 PKG, they are two separate processes. People are able to decrypt PS4 files because they have a secret jailbreak method which works on the more...

Extracting things from FFVII Remake would be the same as what was done for the demo version so that part won't be an issue for you. Of course the problem would be getting the files, for a while now there is a PS4 scene that has jailbroken the most recent of firmware's and they share the files in sec...

I've attached an updated txnextractor, this is how to use it; you can use it by doing txnextractor.exe [txnfile] [cache_d.dlz] [cache.dlz] or if theres just one file that doesnt use mipmaps txnextractor.exe [txnfile] [cache_nodld.dlz] I'm not sure what tool you're using for getting files out, hopefu...

Best to just wait for the PC version, it'll be easy at that point.

I've made a maxscript to import models from the Portable Metal Gear titles into 3ds max. Supports mesh,bones,skinning and applys textures if you have the textures with their hashed name in a 'textures' folder. Some files seem to be using a compressed vertex buffer and there isn't support for that ye...

Hello everyone, recently a group of us who have previously created tools and reversed file types for metal gear solid games decided to create a wiki to share all of our knowledge. A lot of it is work that we have done alone over the years and kept knowledge to ourselves on. We decided instead to col...

I made a post about a wiki and discord we have made around Metal Gear Solid Files and Tools - viewtopic.php?f=28&t=16274
