![]() ![]() Having JIT privilege means that fully compromising the emulator, including the compiler co-process, would grant the ability to run fully arbitrary native code (not just ROP) on the PS4/PS5 without the need for a kernel exploit. Since the PS2 emulator is really a PS4 title that runs due to backwards compatibility, they were unable to make changes to the software, and so its JIT privilege had to be spared. Sony aggressively removed JIT privileged attack surface from the PS5, disabling JIT in both the web browser and the BluRay player. The PS2 emulator is some of the last remaining JIT privileged code on the PS5. This is particularly valuable because access to running just the subset of officially available PS2 games on these platforms is being charged at the highest tier of PlayStation's new subscription service. ![]() I settled on attacking the PS2 emulator, which turns out to be a very appealing target for a number of reasons:Įscaping it would grant the ability to run pirated PS2 games on the PS4, PS5, and potentially also the PSN cloud gaming service. It's been a long time since I last worked on any modern PlayStation hacking, but with the release of the PS5 and the introduction of PlayStation's bug bounty program, I was motivated to attempt some kind of exploit chain that would work on the PS5. Note that these vulnerabilities were discovered and reported back in September 2021, but I was only able to publish this now. See also Part 2, covering the next part of the exploit chain, and PlayStation's response to the research.įor the impatient, a demo video for the first part of this chain is presented later in this article. In this article I will discuss how I successfully escaped the PS2 emulator developed for the PlayStation 4. PS4 also has ps2 games but their selection is limited.Mast1c0re: Hacking the PS4 / PS5 through the PS2 Emulator - Part 1 - Escape Initial publication: September 14th, 2022 PS3 still offers ps2 games for sale for cheap prices. There's also the option of getting a ps3 whether that be Backwards Compatible or not. I can't get over how good games look through emulation.Ĭan run games in higher resolutions for modern displays.Ĭertain games can have compatability issuesĭepending on your hardware some games can be hard to emulate. My preferred way - pcsx2 with a wireless xbox controller. Gathering various scalers can be expensive. Practical - ps2 with component cables hooked up to scalers How do I go about fixing this particular gap in my gaming experience?ĭealing with a crt can be cumbersome and takes up a lot of room.įinding a good crt can be really difficult depending on where you live. So I dunno, I feel like that's more of a question of whenever I can be assed to get a PS5 or whatnot, I'll do that. PS2 games are available digitally through more modern systems, but then that's going to be limited to what's been made available. I believe that early models were backwards compatible with PS2, plus it naturally gives me access to another console's library as well, and I have a bunch of Game Archive stuff on my PSN account which I've been playing on my Vita which I believe I'd also be able to play on a PS3. The next thing I was thinking is that I could get a PS3 instead. I also don't think they'd natively work with modern TVs? ![]() But I've probably been spoiled by more modern systems, and so will inevitably get pissed off at memory cards and whatever nonsense, and would rather want more convenience. Any forgotten thing that I could get on PS2 I should be able to play on PS2. PS2 games are made to play on it, so it presumably has the best compatibility. I imagine that the advantage of this is that, well, it's a PS2. The boring way I was thinking of was to just get a PS2. So I don't really consider that a long-term option. I can run PS2 games on my laptop via an emulator, but it sometimes doesn't run great, and I like having my gaming devices separate from my work devices so that I can focus on one or the other. I'm wondering if that's the right approach, though. My thinking is that I'd grab a few games first and, when it's more convenient, would then get a PS2 with which to play them. I've started picking up some PS2 games I missed out on that I want to try later, but I don't actually have a proper device with which to play them at the moment. ![]()
