Ripping models from ::007 FRWL:: (PSP)

[Sapristi45]

Hello there
I'm trying to rip models from the game "From Russia with Love" on PSP, most of the game's files are conveniently placed in folders named "SOUNDS", "GRAPHICS", etc...
I can't find the characters' models but the levels' models seem to be these *.PSP files in the "ENVS" folder :

I'd like to know if these files are really what i'm looking for, and if it is, it'd be cool to know how to convert them to another format.
thanks in advance!
 (PS: it might be obvious, but I prefer to precise that I own a physical copy of the game)

BTW, I don't know if that helps but using a Hex editor I noticed that each one of these files starts with lines of text, more speciffically directory paths.
