This repository is a work-in-progress to create a simple unpack and packing tool of .ucas and .utoc files. If this succeeds, it would make it possible to create mods for games that use the new .ucas and .utoc file format.

Showing this error when unpacking a .ucas file error

gitMenv commented 1 year ago

The unpacker is currently able to parse and unpack the game files from Grounded. If it does unpack other .ucas/.utoc files, that is great! In this case, it apparently doesn't. I am working on a solution to this, extending the "unpacking support" for more utoc file types. This will be a DLL that can be used with any C-like programming language, but it will take a little bit more time. In the meantime, could you attach the packchunk0-Android_ETC2.ucas and .utoc files somehow? Then I can try to make it work with those files as well. edit: accidentally closed it when commenting :s

I have found the differences between the Grounded game files and the files that you sent. I also implemented the decryption to actually use the AES decryption. I have done major reworks to the code and it's entirely different now, so I will have to restructure a few things before I can push it. In the meantime, I was able to unpack the game files from the .ucas/.utoc files that you sent, which I'll post here: link:- https://drive.google.com/file/d/1A_nnXRoxB9xkfyGuCidsxDLnyGSmcs0l/view?usp=sharing Maybe you can do something with it :)

Yeah I've made changes to some of the uassets file. I need to repack them . So, without your tool I can't do that.
