I am guessing you have a video game or 2 laying around somewhere yes?
I would suggest you look at all the small print especially on the back covers along the bottom
Go to the official sites of ps3, xbox, go to the official auzgame shops too, even look into the "legal sections" etc etc
You would have to dig deep,
But if you would kill for it, well you dont have to,
just use your search engines wisely
Let me know how you go
