You can load up *.CDI images up with Deamon Tools. *.NRG may be loadable too.
And figuring file formats is one of the things I'm learning myself now. All I can say is that you'll need to find some kind of tutorial to explain the basics. And then alot of hex. But you also need to decide how you want to import (Maxscript, QuickBMS, Standalone converter, Python etc.
Alternatively you could try out a few print screen rippers on the HD re-release.
