Rigged Model Ripping from PS2 in DAT and HED Help

[ProjectAlpha]

Hey there. So, I figured considering how many obscure games are able to be easily extracted with rigging in-tact, there must be some sort of overarching tool that works to extract data from the PS2 with some alternate methods or something. For me, I specifically have been looking for a way to rip rigged models from Cowboy Bebop: Serenade of Serenity for the PS2. I cannot seem to find any way to retrieve the rig itself, which considering how intricate the models are, including facial rigging and mouth rigging, is quite frustrating. After opening up the ISO, there seem to be 2 major files in both the DAT and HED format which I assume hold the models. Any suggestions to how to go about this? If I can figure this out, I would like to go through and transfer all the models here for everyone's use. I have attempted to manually extract with PSCX2 and TexMod, but honestly the results are not only subpar, it also has the added problem of being rigless. Suggestions on where to go from here?

Cheers,
