Need help to ripping Lumia Saga

[Simpsons Dumper]

OBBs are binary blobs. They cannot be opened with your typical file extractor, unless the entire blob itself is a recognisable archive. Looking at it, it appears to be compressed and/or encrypted in some way, with no headers present. Without an understanding of how the data is stored within this OBB, I don't think there's much hope.
