What programs can I use to access the files for the girl models and their textures?

 

PC version use JAM files.

Thats an old enough game that maybe the TexMod tool would work for a do it yourself nude patch. YouTube tutorials abound. Of course there used to be an actual Explicit Patch that was released by the developer after its release. You'll have to Google that one, but it was for scripted sex scenes and nudity in game. Not to have characters just run around nude.
