We covered this a few times already so it's not entirely new, but to recap briefly many may recall PS4 game backups ran on PS4 DevKit / TestKit consoles, the PS4 Retail / Debug Game Transfusion Guide, PFS Findings and more recently the PS4 Retail PKG to Debug PKG Conversion... now PlayStation 4 developer @zecoxao announced on Twitter that PS4 game backups on retail 1.76 consoles will soon be a thing that those outside of private groups can finally make use of! :hearteyes:

Before getting too excited, he states in the tweets (below) that it's currently for Firmware 1.76 and below titles... and @SpecterDev also notes via Twitter that later PS4 Firmware incorporates additional protection checks in the kernel meaning it's probably wise not to hold your breath just yet waiting to play newer PS4 game backups until a more recent kernel exploit surfaces publicly. :oops:

Below are some related Tweets for those who still have a 1.76 PlayStation 4 console that hasn't been updated yet:

Cheers to @B7U3 C50SS and @raedoob for passing along the news in the PSXHAX Shoutbox yesterday... BANG ON! <3

Could somebody post the back up file name so I can google them. Ive seen them here before...

Is the special file they were talking few months that got removed when u connect to net still relevant?

A kind of isoloader for retail 1.76 PS4 and for games < 1.76 FW ?

That's a good step in the right direction.

... but:
  • that isoloader will be public ?
  • still no sight about a new public kexploit on > 1.76 FW

If you can start backup
1. extract the param.sfo with the pkg expansion tool (param.sfo is not encrypted)
2. Rewrite SYSTEM_VER
3. Look at the start and end points of param.sfo in the binary editor
4. Replace param.sfo in app.pkg with a modified version in the binary editor

With this I feel like I can run the game I need FW> 1.76, is it my imagination?
