Hello.
I tried to find a solution for error NP-34940-0, but cannot find anything on the internet about this error code anywhere.
I made a personal dump from my original disc of "Uncharted 4: A Thief's End" and this is the first and only time I have this problem with any of my personal dumps...
hahahaha I'm half way through a bag off my Volcano and my tolerance is way down because I haven't been smoking much lately, so I was a little slow to catch that that was what your angle was
