The Beatles: Rockband ripping help.

Alright!

So for a while now I've been trying to rip the models from "The Beatles: RB"...

And I've got everything I need to done, so far! As in:
Make the ISO.
Rip the files from the ISO.

Link to the ISO: *link removed*

That's it, sadly...


I'm stuck at these couple of files though...

.wad and .ark

NO idea how to get into them, or extract them!


So I'm asking ALL of you to help me get them open!

Thanks for reading, and if you'd like to discuss this more add me on steam, as that's where I'm most active!
