Digimon All-Star Rumble ios

Please forgive me if I posted this in the wrong area I'm new to the forums

So we have Digimon models from DMO but I have question what would it take to rip models from All-star Rumble?

There are two Digimon that currently only exist in that game, Aegisdramon and Shoutmon DX

I found a torrent for the game but no clue how to rip the IOS at all.  Me and some buddies have tried but have failed miserably can someone help?
