Ripping mobile or ios models?

I’ve been trying to figure out how to rip certain models from the Crash Nitro Kart mobile games, or Pac-Man Kart Rally, i know how to go about extracting mobile games that use Unity, but these don’t, i read in forums on VGResource that people use Bluestacks and 3D Ripper DX, but it doesn’t seem to open if i try to launch Bluestacks through 3D Ripper, i tried Ninjaripper as well, Bluestacks launches, but it doesn’t attempt to rip anything, is there a way to do something like this at all?

Do you know what engine the game runs on?

no, i tried searching to see if i could find it online anywhere, but i couldn’t find what either runs on

i could only find Crash Bandicoot Nitro Kart 2 on iTunes only, couldn’t find an APK even like the Crash Nitro Kart 3D or Pac-Man Kart Rally
