I've updated my personal collection of Frostbite dumping scripts (which are mostly based on Frankelstner's original scripts, but heavily modified over the years for completeness' sake) in order to make them work with FIFA 17, and I thought I'd share them with you.
They can currently successfully extract and decompress any CAS-based content, including ebx files, resources, and chunks, and also fully process and dump ebx files in the usual text format one can expect from Frank's scripts. Please note that they currently do not support non-CAS based content (such as self-contained SuperBundle content or patch data), and that they have only been tested to successfully work with the FIFA 17 Demo.
You can grab the scripts from here
In order to extract your game's data make sure you have the 64-bit version of Python 2.7 installed, extract the scripts somewhere, and then adjust FB2Dumper.py and ebx.py so that they point to your game directory. Afterwards, simply run python FB2Dumper.py
followed by python ebx.py
(after FB2Dumper is finished) in your command-prompt and you should be set to go. Please note that the ebx dumping script can (and probably will) use up all of your Disk I/O and quite some CPU.
If you encounter any issues feel free to let me know, but keep in mind that I don't have the full game at my disposal, so any issues related to that will be relatively hard for me to resolve.
