A few days ago, scene member Zecoxao had shared a technique to run backup games on PS4, for owners of a console running system update 1.76 (currently the only fully hacked PS4firmware). Progress is being made daily on this technique since it was announced.
While the technique used is still a bit involved, and the number of owners of such an old firmware is really reduced, this might very well be the first time a way to pirate PS4 games is made widely public.
Zecoxao says the technique will let people run any PS4 game (that requires firmware 1.76 or lower), as well as, ultimately, native homebrew.
In particular, Pockets_69 has shared a video showing the infamous Silent Hill P.T. Demo running on firmware 1.76. This is allegedly a backup of the game, which in the video is shown hijacking another game at startup (infamous second son).
Progress has been made recently to make the technique more user friendly, and it seems the latest kernel patches that have been distributed by the team now allow to load any game without a patch. Zecoxao says this has been tested on 3 games so far (P.T., Angry Birds, and Metal Gear Solid Ground zeroes). The games, however, must be obtained in decrypted form, something that is only possible to do from a hacked console. Here again, running 1.76.
A lot of people on recent firmwares have been asking for the hackers to make the solution available on firmwares 4.xx, although this is not up to Zecoxao and others: The technique might work on recent firmwares, but it would require a PS4 jailbreak on 4.xx to enable it. Until then, we can assume Sony is safe from massive piracy of PS4 games.
As always when it comes to piracy we are not sharing links directly here.
