As someone who isn't in the jailbreaking space I don't really know what this means. Can you sign your own PS5 code and run it on the hardware?

These keys are symmetric, so they can be used for decryption. With these symmetric keys you might be able to decrypt games, videos, save files etc sitting on the disk. I don't believe signing will be possible, nobody uses symmetric keys for signing games.

What this does is increase the possibility of someone finding how to bypass the signature verification check and then running their own code.

I live in a third world country. What's funny is we have a lot of PlayStations and powerful video cards and top-level processors available. We just don't have any money to buy them. Maybe I should set up a mail-order business to serve Western hardware enthusiasts.

How much does an RTX 3080 Ti 12GB cost in your country?

Not the OP, but in India, the lowest priced one I could find was from ASUS, which costs around $2600. I don't think the vanilla RTX 3080Ti is available here yet. The most expensive one was from MSI which costs around $3200. Whereas PS5 (official price i.e. without considering the shortages) costs $675.

I'd be surprised. The PS3's keys were leaked too (by the same group, in fact), and Sony managed to put the genie back in the bottle in a pretty amazing way.

Is there any reference to how Sony re-secured the PS3? All I'm aware of is the fact that they killed the ability to run Linux on PS3 because they couldn't re-secure it while retaining the ability to run a different OS.

Wait, wasn’t it the other way around? There was that fail0verflow slide about how the PS3 took unusually long to crack if you count from the release, but essentially the same time as other consoles if you count from the moment one couldn’t run other OSes on it.

"I want to play pirated games" is a perfectly legitimate reason

This is the true reason that I feel like everybody are dancing around. Let's not lie to ourselves, hacking consoles in PS1, PS2 and DC era was for pirating games. Running unlicensed apps or linux was just a nice side effect of true goal. This days it's far less popular because of size, connectivity and prices of games.

In that era , for me, it was primarily to get around region encoding.

We didn't officially have PlayStation in our country (India) at the time. The only way to get original games instead of pirated ones was to import, usually when a friend was traveling. But region locking was a curse.

I'm so glad region locking is pretty much dead. I believe the 3DS was the last mainstream region locked console? Which again was ridiculous given its the one people would take when traveling.

>Governments will usually demand you register a company in order to be able to legally export them. Nah. As long as you don't sell many, you can get away with just marking as gift and putting a value of 20 USD on the package.

I'm sure customs officers around the world have never seen this trick before...

Oh, I'm sure they see it every single day, but nobody cares. They're actually less likely to hassle you if you write a low value on the package - can literally shave a week+ off of delivery times.

This would make reverse engineering of the PS5 firmware possible, and from there, open possibilities for finding future exploits and/or write custom firmwares or Homebrew enablers.

I don't own a PS5, but Xbox seems to be pretty much a PC [1] (weeeell, like a Chromecast-style PC anyways).

> Jailbroken consoles are not worth it anymore since they are so close to computers in features and functionality

With around the same graphics power as a Radeon 5700xt/6700 card, with the whole PS5 system costing around the same as that card, a jailbroken console actually looks like pretty good value right now. If it could be broken enough to run a general purpose OS with acceleration enabled.

The cell CPU was something like a dual core with 6 additional, specialised stream processors. I think the closest analogue might be a a CPU with a few cuda cores on the die? It didn't work too well from my understanding, difficult to develop anything that could make use of those streaming cores that was worth it over a traditional multicore chip with more cores. Useful for scientific community though. If anyone knows…

The Cell was a single primary CPu core, with seven SPU (technically eight with one disabled) cores. The SPU cores were basically used heavily for any background data processing that might align well with what GPU compute is used for today.

The primary core either had a twin or some sort of SMT going on, it presented to linux as two cores.

If only people could obtain a Playstation 5 to go along with them.

Here in Australia we put our names on a waiting list at one of the big name retailers, just by walking into the store. About a week later we got a call that there was stock.

So while the stock doesn't hang around, it seems like it is now at least possible to get one without too much fuss.

What do you mean ? Here in Hong Kong (hardly the west), an RTX 3080 is around 1000 USD, how much is it where you are ?

New RTX 3080 sell on US eBay for US$1500-1600. RTX 3080 Ti for $2000. https://www.tomshardware.com/news/gpu-pricing-index>

Well, If you look at both the PS5 and XBox One X, both of them are running customized AMD SoC's. But basically, that's just a AMD APU. If my memory serves me correctly, the PS3 for comparison had a custom Cell CPU which was used for supercomputer clusters. https://en.wikipedia.org/wiki/PlayStation_3_cluster So they must have had some kind of edge compared to normal PCs.

The cell CPU was something like a dual core with 6 additional, specialised stream processors. I think the closest analogue might be a a CPU with a few cuda cores on the die? It didn't work too well from my understanding, difficult to develop anything that could make use of those streaming cores that was worth it over a traditional multicore chip with more cores. Useful for scientific community though. If anyone knows…

My understanding is that each SPE core was individually assigned to physics, lighting, AI and other tasks, as tools for developing multi-threaded code were not that common at the time. The Last of Us is supposed to be one of the very few that actually used all cores.
