Is there a way to get or to rip MGS1 Models

Hi there my name is Xris, I've been trying to get my hands on the Mgs1 models from all different places and I always come out empty handed, I am also aware that there were a few models but the ones I need to get  are the indoor genome soldiers, Meryl, Otacon, Sniper wolf, weapons/Items,vehicles Liquid and Etc. Is there a way to extract them through the games files /Rip them out because I'm having trouble 
so if anyone knows what I should do or if anyone has them please let me know.





Thank you.
