Release: PS4 FPKG Enabler for PS5 4.03, by Sleirsgoevy

Following the recent fpkg-related commits to his PS5 hacks repository, Sleirsgoevy has released PS4 FPKG Support for the PS5, as a “fpkg enabler” payload for the PS5. In other words, PS4 game “backups” are now a possibility on the PS5.
The PS5 can now run PS4 game “backups”
Thanks to work by Sleirsgoevy over the past few weeks, PS4 fpkg support has been fully implemented on hacked PS5. Multiple people have confirmed the release does work, although some apps and games might crash, or not load properly. Modded Warfare has confirmed that some PS1 and PS2 games (packaged for the PS4) also work.
It is also worth mentioning that these release only works on firmware 4.03, due to some hardcoded offsets (specific to that firmware) used in the mechanism.
Should you update your PS5 to 4.03?
Although a lot of hackers are working exclusively on PS5 4.03, and this impressive release is only compatible with that firmware for the time being, I personally wouldn’t recommend updating to 4.03 if you’re on a lower firmware (well, 4.02 might be the exception here).
For now, all 4.03 would give you is the possibility to run PS4 game backups, something that is already possible, and in better conditions, on a hacked PS4. Although the PS5 does give a performance boost to most PS4 games, in its current state, the hack is reported to crash quite often, and not work with all games yet.
This is not to say that this features will come to lower PS5 Firmwares any time soon. A lot of the work done by Sleirsgoevy is very specific to 4.03, in particular with lots of hardcoded offsets that are “difficult” to find for other firmwares.
Download and test: PS4 FPKG Support on PS5
Update: If you are having issues with some games not running, Sleirsgoevy has published the following tip:
As a reminder, you will need a PS5 running firmware 4.03 to run this payload.
You can Download the payload here. You might need to use Sleirsgoevy’s version of the PS5 exploit (e.g. his version of the webkit exploit) though. Last time I checked, his payload format isn’t compatible with the version that is most commonly used, based on SpecterDev’s code.
The source code can be found on Sleirsgoevy’s github.

Amazing but I feel sorry for anyone who has a hackable PS5 but can’t use this because they have a FW lower than 4.03 lol the temptation must be real for them
Nice! Finally a real big step!
This reminds me of the time when the Vita could only run backup PSP games but not backup Vita games. We all know what happened with it later on. Hopefully the same thing happens here soon :).
“something that is already possible, and in better conditions, on a hacked PS4”
Really? It just came out a few hours ago and that’s what you have to say about it? How about “This is great news, now we can look forward to some ps4 homebrew in the future on the ps5”?
I just want people to be very clear on what this gives them, from an end user perspective, and why I don’t think it’s worth jumping onto 4.03, in particular if you’re on 1.xx, 2.xx, 3.xx. I’m obviously very excited, and none of what I say takes anything away from the technical achievement. In particular given the circumstances of how Sleirs has achieved that, with XOM. Sorry if my writing gave the wrong impression. I’m super excited.
Does this look like something that will soon be ported onto 4.50?
Congratz Sleirsgoevy!!! You’ve made it 🙂
wololo please make slairsgorvy ps5 fpkg payload for esp8266 thank you
Just use my files and replace the html files with sleirsgoevy’s:
– https://github.com/frwololo/PS4_PS5-ESP8266-Server/releases (get the release that matches your device)
– go to the admin 10.1.1.1/admin.html and erase/replace as needed with the files from Sleirsgoevy: https://github.com/sleirsgoevy/ps4jb2/tree/ps5-403
it is not working form me i was tried everything – just blank screen on PS5.
Wait, it’s finally happening?!!!! I literally put my PS5 in my garage last week.
This is still great progress despite the limitations and issues.
I’m still hoping for a way to decrypt my PS4 content on my 4.50 PS5 as my 9.00 PS4 is not my primary active PS4 but the 4.50 PS5 is active.
Still get any PS5 payloads to compile.
Great work everybody.
Testing this, opoisso games installing nice(EAFC24, Martha is Dead), Cyb1k games error107520-5.(Lies of P, Atomic Heart) …
My body is ready time to test Psvr
Noooooo I finally opened mine cause I was hoping it was on 4.03 and it’s on 3.20
Can you put together a video for package merging ps4 games for PS5?. Many people are not very clear on how to do this properly.
DLC fpkg not working?
Trying Atomic Heart and Resident Evil 4 Remake – DLC not working.
