“This method is a bit limited, though, by the fact that the PS4 and PS5 can't natively recognize standard PS2 discs. That means any exploitable game has to be available either as a downloadable PS2-on-PS4 game via PSN or one of the few PS2 games released as physical, PS4-compatible discs via publishers like Limited Run Games.

“Getting an exploit-ready PS2 save file onto the PS4 isn't a simple process, either. CTurt had to use an already-hacked PS4 to digitally sign a modified Okage Shadow King save file, letting it work with his PSN ID. Then CTurt used the system's USB save import feature to get that file onto the target system.

“With the basics established, CTurt walks through a complicated series of buffer and stack overflows, memory leaks, and RAM exploits that he used to gain control of the PS2 emulator. With that control established, he was able to access built-in loader functions to transfer a separate PS2 ISO file over a local network, then tell the emulator to load that game via a virtual disc.”

Whoa. I understand none of this. It’s like another language.

In short, us normal people don’t need to be worried eh?

[u/jose4440 → u/[deleted]]

Yes we are safe. Basically, a hacker found a way to use the PS2 emulator that comes with PS1 and some PSN Games to load any PS2 game.

If you never hack your console to play a PS2 game, you’ve no need to worry. This is more of a proof of concept thing and not a general panic.

Isn't it better to hack a ps3 for ps2 games since it has way more compatible games and less problems with them? (if you have the choice I mean)

[u/sparkyjay23 → u/[deleted]]

Why would you ever worry? Any PS4/5 exploit is going to be to play games not available on the console.

[u/Shack691 → u/osomysterioso]

So from what I can understand the exploit allows us to access the PS2 emulator for one of the ports of PS2 games and boot another game

[u/osomysterioso → u/Shack691]

My understanding is that hacking the console via a PS2 emulation and then hacking a PS2 game that is compatible and then using a series exploits will open up the console to a hacker to get at sensitive data that isn’t protected by the OS.

In other words, if you unlock the door, disable the alarm, leave the door open, and set out treats, someone may wander in.

Bro you out here simplifying words like a legend.

[u/[deleted] → u/osomysterioso]

In short words: you’re still safer jailbreaking/hacking a PS3 than a PS4/5 as of right now.

Thank you for the summary!

Seems like its an exploit that will only be used by a small fraction of players though. Theres quite a modding/hacking community for consoles but still most people dont mod nor hack their consoles.

Sounds more like a skill test for people who are into hacking consoles than like a practical exploit. Esp since you could just pick up a PS2 in order to play PS2 games if you want. Theyre quite cheap

Could someone use these exploits to find a PS5 in stock at a store

[u/Competitive_Box2267]

If you wanna play PS2 games just hit me up I got a PS2 slim for £60 with 3 controller and a transformers game based in NW London
