HAHAHA, correct me if I'm wrong, but sounds like he wants to rip the files from non-unity based games and import them into unity!
Hate to be the bearer of bad news OP, but nobody has figured out PS1 model ripping since it's such a pain in the ass format, so getting every asset from DW1 is not going to happen. As for DMO, I gave it a try but couldn't get the files to extract. It's possible, since there are models on tMR, I personally couldn't figure it out myself. Maybe you will have better luck!
If you do figure it out. I did toy around with Unity myself at one stage. I found ripping animations as FBX and importing them worked. Might want to keep that in mind!
