activate or hex edit us psn demos possible?

Post by stingray1059 » Thu Feb 16, 2012 9:54 am

ive notice that all game demos in the us psn store has the same size as the full game.( check asphalt, rayman, lumines and little deviants.)

if you play the demo you just need to activate it in order to play the whole game. so when you download the demo, you also downloaded the game but with restrictions.

can someone, backup the game to the pc and edit it so when you transfer it again to the vita it will be read as a full game.?

apprently, the michael jackson experience has this bug, when you download the demo, it will be downloaded as a full game. but sony found the glitch already and removed the game in the psn store.

If you know how to decrypt, and then reencrypt/sign the game, it should be feasible. If you don't - no.

I was actually talking in general. Right now, SKFU appears to be the only one who can decrypt Vita games.

You can't encrypt for Vita. End of game.

It should be mentioned that this forum does not support any kind of activity that would allow you to play commercial games for free without the author's agreement. There's a blurry line between playing backups and pirating games. I think bypassing DRMs on a demo in order to play the full game for free is crossing that line. I'm not locking this topic for now, but please be careful what you discuss on this topic.
If you need US PSN Codes, this technique is what I recommend.

i think as long that there are no links on where to get games. i think its fine.

anyway.. im hoping TEAM DUPLEX will do something about it. they also used demos in some ps3/psn games in order to be played in full and be playable on 3.55 fw.

i wish it could be easy as overwriting the .exe file in C:\program files\ just like in some demo/trial games and apps in windows xp. but knowing sony, it will be very hard.

Err... no. Windows EXEs are not encrypted.
