Models from The Legend of Spyro: The Eternal Night Wii or PS2

[Xurrias]

So as the Title says, I´m on the search for models from "The Legend of Spyro: The Eternal night"

I actually tried myself on ripping files from the ISO and got some file out of it.
But sadly my Skills aren´t that good to actually understand how to convert or extract files from this game files.

I searched on the web for solutions. I saw that there was a website, thats now only accessible via Web Archive, but I don´t really understand the procedure of the ripping back then. 

I hope someone can, at least, tell me if its even possible to extract the files.

Thanks in advance
