How to extract files from Warner Bros Ent. .DAT file?

[Edmonds]

I'm trying to get the animations and models for Lego LoTR for the Wii, but they all are stuck behind a .DAT file.  Any ideas on how to break this?  I think they're in MOBJ format, but that's only through a hex editor, so I could be wrong

Hi - I should note that most of the time the folks who develop a game (in this case, Traveller's Tales) are different to the ones who publish it. As for how to decompress it, you can use this QuickBMS script to do so.
