Rino Fast

Good time of day. I have a question , earlier there was a console (PS3)
She was not bound , had played himself online in drakes deception and was the happiest.
In connection with the life situation , was forced to sell it.
A few days ago , to be precise , yesterday. Bought a console. (The same PS3)
Bought b/y .
People the sale , has given 4 disks and 2 controllers.
Now the whole point of this topic.
I especially do not rummage in them. And all my knowledge about the PS3 is limited to gaming and basic knowledge of its functions.
People said that she was STITCHED AND PULLS ALL ANY GAMES.
Starting to surf the Internet, I came across that when stitched console in the "game" is neykov 2 folder. I have not found.
So , as the Ball seamed exactly to check whether the console ?
If she's stitched , then on what system to install pirated games.
And in addition another question.
If the person who gave me the discs with the codes of activation , will I be able to activate on your account PSN or codes-activators are disposable ?
Thanks in advance :)
