Part way to finding a vertex header, need some pointers to go the rest of the way

It'd be easier if you were to extract the files and locate which file type stores the models you're looking for.
If you're able to find such files, you can post them here and I'll take a glance at it.

That is true, I should see how to open multiple with python. It would be easier to sift through a few files worth of vertices and false positives rather than an entire savestates worth.
