FPKG Support might be coming soon to PS5 chepgameps3.com

PlayStation scene dev Sleirsgoevy has dropped some new changes to his PS5 github repository, which is bringing the scene closer to fpkg support on the PS5. Before everyone blows up on this, we’re talking about PS4 fpkg support at the moment.

PS4 FPKG Support coming to PS5 soon-ish?

It is no surprise that the PS5 has strong backwards compatibility with the PS4, in particular since the two consoles use the same overall hardware architecture.

The scene got on fire a few weeks ago when “installing” PS4 fpkg files apparently became possible on the PS5, but as many have warned, the appearance of a succesful install doesn’t necessarily mean much, and in particular it certainly didn’t mean the games would actually run, at the time.

However, getting homebrew (and, yes, piracy) support for PS4 titles on the PS5 now seems like it could become achievable, and people believe that Sleirsgoevy’s latest entry to his bd-jb branch might bring fpkg support to the PS5 sooner than we’d think. In the developer’s words:

it’s basically the core code for enabling decryption of ps4 fpkg files. they still don’t run properly, but reading the filesystem seems to work fine

technically they [fpkg files] are encrypted, just with a well-known key

The developer has however sent a message of caution. When asked if PS4 fpkgs could run on PS5, he replied: it should be [possible], but kinda nobody knows for sure until it runs

Flatz introduced FPKG concepts to the PS4 scene in 2018, and since then this has been the main mechanism being used to install unsigned content on hacked PS4s.

Download Latest PS5 BD-JB code from Sleirsgoevy

You can download the latest code from Sleirsgoevy’s bd-jb repository here. For most people, this will be useless in its current state. AFAIK this is only compatible with bd-jb for the moment (not webkit), and most likely only with Firmware 4.03 as I believe this is the firmware Sleirsgoevy has been working with for now.
