B777 CBT
Hi Shaka Zulu,
There is a B777 CBT available, for both the -200 and -300, which I did for my type rating with my airline. There are also B747 CBTs available, in case you're wondering.
Unfortunately, I do not know how to 'extract' it, it's installed in my company computers. Might be able to find it online at ebay or something, if someone's selling it.
Hope this helps.
Cheers!
