BLACK ROCK SHOOTER: THE GAME (PSP) .mdl vertex/bone weights

[Grounder]

Way back in 2013. chrrox over on the XeNTaX forums posted a Noesis script for Imageepoch PSP games, with the strange quirk of being able to rip models with bones, but not vertex groups.  Naturally, this meant that the armature was barely usable beyond a general reference point.  A decade later, and I'd really like to be able to get the models out of the game in their entirety.  Attached is the script, and a few sample .mdls

Is there also an archived script to unpack the FCHR bins?
