Aww, that sucks. I was hoping it would be like Dreamcast games, which had a readable CD portion where devs usually added bonus goodies or some identifiers (like ABSTRACT.txt, BIBLIOGR.txt, and COPYRIGH.txt). That data is specific enough that they could function as a key disc.
Thanks for clearing that up.
