Question about emulation

[Cyber Akuma]

Taken from www.zophar.net:

Caustik's XBOX emulator, Cxbx, is looking very promising. It is now playing the intro movie to Turok Evolution, so if you have this game, go ahead and give it a try. Also new in this version:

So if you have this game give it a try? Does he mean a copy or is there a way to read the original disk on a PC? He didnt sound like he was talking about a ocpy but I thaught that reading them on the PC was near impossible?
