Dumping Files From The Sims 3 Pets on X360/PS3

Hiya! I am in the market to see if there have been any previous attempts to crack open the Fort Knox hellscape that is whatever Edge of Reality did to the DBPF files. The sheer amount of insanity I have gone through just to try and get the littlest bit of data (objects, rabbit holes, terrain sprays, even world geometry) has left me completely out of ideas, so I figure I would ask the community before completely giving up. s3pi has proven fairly useless to me, and any attempts to recompile any of the dlls to support the unique bit headers has been futile.
There is absolute zero documentation on the game, RPCS3 can't even crack the game open in the memory viewer (hard crashes it.) Are there any veterans here who could potentially try and lockpick the impossible?
