PS2 Emulator

You cannot go wrong with PCSX2, the only PS2 emulator for PC with 100% games compatibility. They achieved this feat in November of last year. The console emulator is available on Windows and Linux PCs, and they have added Vulkan rendering recently.
hpsx64 is a relatively new PS emulator on the block, been in active development since 2018. We get two gamepads support for games such as FIFA, Tekken, Street Fighter, etc where local multi-player is essential to the gameplay.
At the last leg, we have PS2Emu, an experimental PS2 emulator which has been in active development for a while now. Audio, graphics, and general control require plugins to be manually transferred to the plugins folder.
With emulation and compatibility in mind, PCSX2 is the best PS2 emulator for PC right now. If you are looking for a better user interface and features then RetroArch with a PCSX2 core would do the job.
In this article I will discuss how I successfully escaped the PS2 emulator developed for the PlayStation 4. See also Part 2 (to be published), covering the next part of the exploit chain, and PlayStation's response to the research.
Sony aggressively removed JIT privileged attack surface from the PS5, disabling JIT in both the web browser and the BluRay player. 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.
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. This would be especially convenient on the PS5 because the newly introduced hypervisor enforces that code pages (both userland and kernel) are not readable, and I don't have the patience to try to write a blind kernel exploit again as I did when I ported BadIRET to the PS4 without a kernel dump.
It's my interpretation that the existence of games with special privileges, like the PS2 emulator's JIT, fundamentally violates their own security model because it leaves privileged code with no readily available mechanisms to patch potential future vulnerabilities.
Given PS2 code execution from any of the 3 identified exploitable PS2 games, I started reverse engineering the emulator itself. The very first thing I looked at was the memory read/write callbacks; you can see on ps2tek that some addresses control various PS2 hardware functionality, and so accessing them requires special code for the emulator to handle those requests.
Note that other registers like 0x1f402016 (CDVD S Command), and 0x1f402004 (CDVD N Command), are also vulnerable to buffer overflows, so in total there are at least 4 variant vulnerabilities like this, but since the emulator is quasi-unpatchable, and PlayStation's bounty program stopped accepting PS2 emulator escape reports after the first one, there is no reason to find or analyse other bugs.
If we go back to the memory read/write handlers, we'll see that the code handling virtual memory addresses backed by Random-Access-Memory regions are implemented using pointers. For instance, when the PS2 performs a 32-bit write to IOP RAM, the emulator will eventually perform a write at its native iopram pointer:
By overwriting it, we will effectively remap the emulator's internal pointer to IOP RAM (from its normal value of the fixed address 0x9000000000), so that any read/writes we make from the PS2 to the IOP RAM region will be redirected to our new address.
In practice, this primitive is not very reliable because the emulator runs multiple threads, which may start to behave unexpectedly if we redirect this pointer, so I didn't end up using it in the final exploit. Let's continue browsing for other corruption targets.
You could probably also copy games off USB storage by manually porting over a USB and FAT implementation (since mount syscalls are restricted), like I did with my native GameBoy emulator Proof-of-Concept for the PS4 1.76 WebKit and JIT exploit.
Once the ISO file is somewhere accessible on the filesystem, it was just a case of locating the emulator's code responsible for opening the disc file (/app0/images/disc01.iso) by setting a breakpoint on sceKernelOpen, using the exploit to call it (with a traversed path like ./../bla/boot.iso to bypass some internal check), undoing any left over corruption, and finally having the PS2 code call LoadExecPS2 to boot an ELF on the newly mounted virtual disc to start the new game.
Note that the emulator was configured specifically for the game it was bundled with (in this case Okage Shadow King), and whilst some of the configuration may be tweakable at runtime through the exploit, expect compatibility with other games to be spotty in general, although at least Klonoa 2 seems to work fine as is (an otherwise $40 dollar game).
Regarding that goal, escaping the emulator is just the first half of the chain; we can't yet write arbitrary native code since our application process only has permission to map JIT shared memory as executable, not writeable.
Emulation is a necessary part of video game preservation and history. Most companies don't seem to be too committed to ensuring you have access to their legacy games, and tracking down old hardware and copies can be expensive, so emulation helps a lot. One developer was working on a PS2 emulator for Android devices but has since quit due to \"neverending impersonating, complaints, demands, and now death threats.\"
They add that the main issue is the amount of emails they get. \"Every day, I get 15+ emails nagging for 32-bit support (sometimes demanding I 'stop updating 64 I need to play'), whinging about bad performance on slow devices, or other rubbish like 'make a ps3 emulator', 'fix my game very soon I need it'. My inbox has over 6,000 emails since launch in the last year.\"
I used PS2-FPKG_v0.6 converter with the config for PS3 game, it's already present in converter. When converting, check the box Auto-Add PS3 Config, and uncheck the rest, then choose Destroy All Humans V2 emu, just put this Destroy All Humans V2 emu folder into PS2-FPKG_v0.6\\emus\\ and just select it in the program. Use The suffering 2 emulator configuration inside config-emu-ps4.txt.
Update: Use config = --vu0-const-prop=0 #to get past the loading freeze, --vu1-const-prop=0 #to get past the loading freeze #emu used=jakx v2. Widescreen and 60fps codes can be added. www. psx-place. com/threads/research-ps2-emulator-configuration-on-ps4.16131/page-138#post-321894
AetherSX2 is the latest addition to this article, and as of the start of August the development team has release a wide number of incredible updates, making this PS2 emulator a worthy opponent in this article.
Most of the best PS2 emulators are created by members of the retro gaming community, but DamonPS2 breaks the mould. This program is the brainchild of Chinese DamonPlay Technology Co who have created a downloadable product specifically for Android users.
NSX2 is one of the very first PS2 emulators that arrived on the scene. The code is super clean and well laid out, giving other users all the tools they need to successfully build their own programs or further the work started by the developer.
Android users looking for a reliable emulator should check out the next entry on our list of the best PS2 emulators. Golden PS2 looks and plays beautifully and works with a vast range Android smartphones from a variety of companies.
Essentially, emulators play a sort of hypnotic trick on your tech and make devices think that they are a games console. In this way, users temporarily turn their Macs into N64s and their phones into Gameboys without doing any tinkering whatsoever.
The truth is that some ROM files and downloadable emulators are just plain nasty. Finding good programs is the key to a happy playing session, otherwise you might rip off your fingers in a rage and end up feeding them to the ducks.
Good emulators need a good mind behind them, regular updates, and someone/people who know their stuff when it comes to manipulating code. Other emulators that look good on paper end up have zero to few games that actually work for them because the ROM files have been ripped badly.
Naturally, companies have problems with the practice, but it won't stop players - unless they're getting very serious threats from users. And that's exactly what has happened to one PlayStation emulator developer.
In a public announcement that the developer has made by completely shutting down the emulator's site, the creator has said that impersonation and death threats have led them to put the system for playing PS2 games down.
Users of the emulator have taken to Reddit to express their frustrations with the shutdown of AetherSX2, only to be met with players sticking up for the sole developer. In response to a post titled \"what is wrong with him,\" users have leapt to the creator's defense.
\"And you think blasting him on Reddit was the better idea,\" asks another. \"Good job.\" It's a shame that the creator has been forced to step away, especially when video games without emulators are beginning to disappear. Well done, internet, we hope you're happy.
The best part of the best Android PS2 emulator is that improvements are coming all the time. Sure, this software may not be playable on your device right now, but it might be semi-playable in the near future.
PlayStation 2 (PS2) is one of the most successful and widely used console platforms by game lovers. However, the gaming experience on all PS2 emulators is not the same. The processing power of these emulators is unmatched by any other console. There are several PS2 emulators available for Android and PCs, which you can install and enjoy them. You can use any of the PS2 emulators to enjoy your favorite PlayStation 2 games on your smartphone. 781b155fdc
