It's been quite awhile since the last round of PS3 and PS4 Software Development Kit leaks from @KromeMods back in July 2017, but according to rumors via D3fau4 (aka @Defaud) and zavtracast on Twitter a new batch purportedly surfaced including PS4 and PS5 DevKits as a result of a CD Projekt Red (Cyberpunk 2077) leak. 🔥

According to the note pictured below, archive passwords were dropped onto an anonymous .onion site accessible via Tor, however, it also states the archives for PS4, PS5, Switch and Xbox have no password which is welcomed by those in the PS4Scene and PS5Scene. :sneaky:

Based on the images below, the following PS4 DevKits (ps4.7z - 107 GB / 99.53 GB) and PS5 DevKits (ps5.7z - 41 GB / 38.19 GB) codenamed Prospero are included in the alleged leak with Complete File Lists available thanks to @Defaud:

Up to now we haven't seen any public PS5 DevKit leaks, and the previous PS4 DevKit leak was version 4.50... so quite dated considering Sony is currently on PS4 Firmware 8.50.

:idea: One application many in the PlayStation 4 Scene are eagerly awaiting is an updated Fake PKG Generator for PS4 Version 3.70 (Build 3.70.7110.1152) to generate FPKGs that never got released due to LM-based drama over DMs, although with today's leak hopefully a newer revision will eventually surface to replace the antiquated Fake PKG Generator v3.38. :ninja: PS4_Fake_PKG_Tools_v3.87.rar (3.35 MB)

:alert: As always, if you have around 148 GB of storage to spare and manage to grab the ps4.7z (107 GB) and ps5.7z (41 GB) archives do NOT share them on the public forums (this will result in a permanent ban), instead join everyone in private by following THIS GUIDE to become Verified via the 'floating' Discord Channel and get your Blue Verified Badge... or simply torrent them to share the love! :lovewins:
M.E.M.E looks like PS4 devkit CP firmware is based on linux ... PS5 devkit CP firmware is based on * ThreadX ARM9/RVDS Version G5.1.5.1 Copyright (c) 1996-2008 Express Logic Inc. :)
PS5 debug packages now have 3 sections on them:
  • FIH part -> the actual content in itself
  • SC part -> the metadata of the package (inside a package lol)
  • SI part -> the metadata of the metadata of the package (inside a zip ROFL)
it seems that the leaked ps5 ***s contain some special pups called CROSSGEN for devkit and testkit units. these can be installed on ps4 kits, both the devkit as the testkit variant.

Everyone, this alone allows for software development. That's about it. Which is awesome! However, this has little to do with exploit finding. It can, technically, but what this would mostly allow is updated tools and such.

As mentioned, the last I'm aware of is 4.50 so we're talking years ago since the last one was leaked. We're all using super-old tools to do everything related to packages, fake packages, etc.

So this is awesome but not the keys to the kingdom or anything.

@Defaud It would be very much appreciated if you can share the file lists for the PS4 and PS5 leaks, to be safe use SPOILER tags like so:

Personally I love collecting such things primarily for archival purposes more than anything else. :kitty:

:arrow: Update: Some additional info for those interested:

Good question. It'll offer the actual software - updated (!) - for the software development kit. The clean room, open source developments are largely based on what was had at the time... which was the 4.50 version. They then build their own version free of the Sony code in order for it to be legal to use. Yet, it was absolutely built off the official version. Any statements to the contrary are BS. Developers at least look at the official builds, if not outright take from it in a re-written but equal sense.

So it really comes down to what the clean room devs could build blind, without the official software. Due to that it's all based on 4.50 and what could be gleaned beyond without anything official above 4.50.

Now they have 8.00+ and whatever changes come along with it. Again, additions will have to be re-written for legality but it's basically a Rosetta Stone for anyone making it open source.

Truth be told, end users won't see a massive change or massive benefits from it. It pretty much only means we get better tools for package file work, fake or real.
