Method for ripping Irrlicht Engine assets?

[Balrogchar]

So, I'm looking to rip from the iOS version of Castle of Magic. I was able to get my hands on the .ipa file, and I'm able to root around in the .app package, but I don't know what to do with most of what I'm seeing. A lot of the things that even have extensions are .bar files. The only real lead I have is a plaintext file talking about compiling the source code of the Irrlicht Engine, attached below. Do there exist any tools for working with that?
