The PlayStation scene has been on quite the streak lately, as not only has the latest console by Sony been exploited to allow access to debug settings in-console,which can be achieved through several methods, be it webkit exploit, BD-JB or through PS2 Classics, but now the exploits can now serve a purpose beyond some proof of concept and some homebrew SDK being available.

On May 22nd, user Sleirsgoevy released a payload that makes use of the currently known webkit and userland exploit for the PS5 to allow dumping decrypted binaries of PlayStation 5 games, although the methodology to be able to do this is still locked to the PS5's exploitable firmware of 4.03, but it should be possible to port the current payload to the latest compatible exploitable firmware, that being 4.51. The dumping method relies on FTP to send the decrypted binary through a connection to another device.

​

While it was already possible to dump PS5 games, it was only possible to do so with the binaries being encrypted, with this new method allowing for fully dumping decrypted binaries now. This opens up the ability for users to dump their own games and preserve them, and this could also open up the doors for work on a PlayStation 5 emulator, since there could now be easier ways to test compatibility, if such a thing were to come.

As a particular side note, user Zecoxao has mentioned that it is now possible to dump the SCE modules of the console as well.

Well spoofing and playing on PSN is a lot harder since it's also server side.

Hard yes but more of a possibility if the right person finds the right files needed.

$oyny is not going to be happy about this.

Isn't that ps2 emulator exploit unpatchable?

Sony don't do force update.

Dumping 2 years old games yay!! Each game is like $5 now. Totally not worth the investment. PC is better

A good start for PS5 preservation, though the space to store all those games is going to be quite something.

For serious collectors space isn't a problem.

Uninformed as always.

Care to elaborate?

Waiting for the day in my lifetime where a PS5 emulator will be available for public consumption

PS3 has only just got there now.

PS4 emulation is available for 2D mostly.

PS5 might be a while yet

Was it not that long ago where we thought cheapo portable ps2 emulators wouldn't be a thing? PS5 really doesn't have that many exclusives for me to care about getting into the emulation side of it yet since half the library is ported to PC and the popularity of portable windows devices increasing.

This is true, and the PS5 first-party exclusives will all eventually make it to PC anyway after a timed period.

I just like to think more about what is possible, in the next couple years we'll probably see Anbernic like devices running rpcs3 smoothly for under $200. It would be awesome to pick up a 5" display and run a PS5 title on it just not anytime soon. Theirs just other options and with Sony getting into PC ports will only be a matter of time before Ragnok (probably butchered the god of war spelling) will be ported.

Great news! But always keep in mind the downside on relying on decrypted content:
We can't use updates from PSN without decrypting those too.

Being able to backup the original pkg files and keys, like we can do with PS3, Vita, 3DS and Switch, is best.
Good for preservation too as we can verify the pkg file itself is correct.

Vita was limited to decrypted dumps for a while (maidump) until nonpdrm
3DS could have used decrypted eshop content too but thankfully tools making GOOD cias were easy to use

Nicee but we are not yet there where we want to be.

We can’t have CFW without keys, and those keys do not reside on the console.

Also the PSN “handshake” or passphrase changes regularly, so even with CFW you would struggle to get online without the latest credentials, honestly: not going to happen.

How can we find the keys?

You have to ask Sony very nicely.

Remember the PS3 scene? There was an algorithmic/cryptographic fail that allowed devs to derive HMAC/signing keys for modding and installing their own firmware, but it was fixed on 3.56 iirc.

This is why 3.55 was golden. For a long time.

The likelihood of Sony making the exact same mistake again is miniscule… but not impossible.

The keys to sign anything are not stored on console. SAMU is used to decrypt things like games and updates… which KEX does without the need for CFW at all. You can get SAMU to decrypt lots of things, but you cannot get it to sign anything.

The dumping method relies on FPT to send the decrypted binary through a connection to another device.

"FPT"? Is this a typo or intentional? Never heard of FPT if it isn't.

Sorry I did mean FTP, my damn dyslexia doesn't let me live
