    Question Compression algorithmus for .cas file

    Hi guys,

    I'm a FIFA modder. The new FIFA (17) game comes out for pc with a new engine. "frostbite" ... they use cas files as data-containers and they are compressed. The compression methode is unknown. We think its a customized LZ4 - but we aren't sure.

    Is anyone here able to have a look on these files? I uploaded a some cas files so may you can try it... decompression this cas files is really needed for us modders... I hope anyone can help, we will try to reward it.

    Here the examples:

    thanks and greetings

    Thanks mate, really happy to found it. Compression in Forums is normally really "empty" not much post, not much threads, not much users with know-how. It looks here a bit different.

    Battlefield 4 uses the same frostbite engine, just check from here

    Also there is repack team that managed to remove videos from the cas files called BlackBox, you might want to ask them as to how did they do it. They did on a game known as NFS Rivals which also used Frostbite engine.
