When a new console generation get's released, there is always the question sooner or later: "Can I emulate it on my PC?"
While one side tries to emulate older Classic Titles on newer consoles - like running PS2 Game Titles on the PS4 - then there are also other people who tries to run newer Game Titles on the PC. And since we speak already about the PS4, maybe we should have a look what those other people are trying to achieve about PS4 Emulation on PC.
Well-known developer AlexAltea is one of those other people mentioned who tries exactly right that with his - as he calls it - "Virtualization-based PlayStation 4 Emulator", named Orbital.
Althought it's in his early stages and emulating a console on a PC was never a easy task in general, this project could be a step in the right direction which looks promising, not only because the PS4 is based on a (modified) x86 architecture as well. And while the latest hacks and exploits for the PS4 gives the developers the opportunity to understand how this console actually works, maybe this could be a chance for programming a working emulator, which would mean that both sides can profit from this project.
Orbital is a low-level virtualization-based PlayStation 4 emulator for Windows and Linux. In other words, it's goal is allowing the entire PlayStation 4 software stack to run on your PC. This is an open-source project, and so any resources/findings are shared straight back with the rest of the community of PS4 developers.
While both the PS4 and computers share the same CPU architecture, it doesn't mean this project is easy. Reverse engineering the kernel and system modules, understanding hardware and reimplementing it focusing on high-performance in a system as complex as the PS4 is an arduous task. Your support will make a difference.
The current perks are somewhat limited but will be improved as the emulator progresses. Feel free to join our Discord server to discuss emulation in general, following the development of Orbital, and getting the latest news about this project.
Disclaimer: This project is in early stages, don't expect to boot the entire system, let alone games. This campaign is aimed at funding the development of this emulator.
The current state of Orbital at booting decrypted kernels can be followed in the issue tracker: both PS4 4.55 and PS4 5.00 have been tested. You can also get ocasional updates and news via Twitter. Support this project at Patreon.
Future plans for the emulator can be found at the Roadmap page.
How does Orbital work without having SAMU keys?
Until keys are dumped, decryption with SAMU will be "emulated" by hashing encrypted input blobs and returning decrypted blobs previously obtained from the actual console.
My kernel dump crashes shortly after booting. Why?
Kernel ELFs generated from memory dumps will not work since writable segments might have been modified into a state where booting is not possible. Please generate proper binaries offline by decrypting ELF segments with SAMU on your actual console, not by dumping memory.
Where can I get Orbital?
This project is not ready for end users. No binaries are provided, so you must build each of the three components (BIOS, GRUB, QEMU) yourself. Furthermore, configuring the emulator to do something will be hard, as you will need to dump and decrypt the entire PS4 filesystem and sflash, including the kernel. You might find hints on how to do this in the few scattered .sh files in this repo. Of course, in the future, I'll make this emulator more user-friendly.
- OS: Windows, Linux.
- Processor: x86-64 CPU with AVX/AVX2 extensions.
- Memory: 16 GB RAM.
- Graphics: TBD.
The following points refer to tests done with the PS4 5.00 kernel on Orbital.
- Implemented bootloader.
- Kernel debugging with symbols .
- Successful kernel initialization on hammer_time
- Emulating Aeolia's UART device (partial).
- Successful driver initialization.
- Adding Vulkan support to QEMU.
- Implemented SFlash access (read-only).
- Implemented Liverpool GC/Starsha.
- Implemented IH ringbuffer.
- Implemented Command Processor.
- Processing SAMU commands.
- Vulkan backend for GFX engine.
- High-Level Emulation.
- SBL ACMgr (0/? completed).
- SBL AuthMgr (1/5 completed).
- Added PS4 HDD creation tool.
As the title suggests, this Emulator is still in it's early stages. Please don't expect that this will run PS4 Game Titles so quickly. As AlexAltea suggested already, the first goal(s) are to understand the hardware and to run the PS4's System Software on your PC. And even when Sony make developing Games easier for the PS4 compared to the PS3 and it's (complicated) CELL B.E. processor architecture, it doesn't mean that emulating the PS4 won't be easier. In fact, speaking of the GPU side of the PS4's APU, there is no official documentation, since AMD provided a custom Graphics Processing Unit for Sony. So you can imagine that there is still many hard work needed and how many tasks you need to Reverse Engineering.
But is it a worth to try? Of course it is. Not only because the CPU is based on x86-Architecture, many x86-Instructions are documented and official available for everyone to read and to investigate. Since other Developers showed already that the PS4 sometimes resembles a PC in several tasks (but sometimes it won't) and while it showed that the PS4 itself was able to successfully emulate older PS2 Game Titles and even Steam OS, this project could lead into a bright future similar to other well-known ventures like PSCX2 for emulating PS2 Game Titles on the PC or RPCS3 for PS3 Game Titles on the same platform.

[Update] multiMAN 04.85.01 - Official Update from deank adds 4.83-4.85 CFW Support + PS3HEN SupportUPDATE 04.85.01 - Improved PS3HEN Support Added
Original: Appears that developer @deank has pushed an official update for the popular PS3 Homebrew known as multiMAN (or mM). We have not seen an official update since firmware 4.82 (albeit from some unofficial modified version, that were not ideal), there was not much of a need for an update since the previous official update of 4.82 worked fine as is on 4.83 /4.84 / 4.85. In that time Sony's changes in 4.8x era of firmware were minimal and presented little changes for the PS3. The only thing that was missing was firmware detection of 4.83 and greater, as it was impossible for the application to know the offsets of future firmware's. However, deank quietly pushed an update via the applications online update. This new update provides official support for CFW 4.83 - 4.85 which will recognize and properly fix the cosmetic issue and display the new firmware presents.
Other then that its the same old classic multiMAN, which is not a bad thing as this was and still is an iconic applications for the PS3. This powerful Homebrew is packed with tons of functionality for your cfw enabled PS3, Regarding support for PS3HEN user's I am not sure as of writing this if this version supports PS3HEN fully, (see 04.85.01 update) nothing is mentioned so we should not assume. On brewology there is an unofficial multiMAN 4.84 PS3HEN version (* in previous releases), but not sure how compatible many of the feature are (maybe we could have user's comment below with some feedback regarding ps3hen) PS3HEN user's in general should also realize that many PS3 Homebrew apps were created with CFW in mind. so there can be compatibility issue with some features..Note that ManaGunZ is supporting PS3HEN w/ a special PS3HEN mode that will disable the CFW features.Continue reading
[New PS2 Exploit] Hacking the PS2 using Yabasic on (PAL) demo disc ( by Cturt )The PlayStation 2 is still in the cross-hairs for many developer's in the homebrew scene, hacker Cturt known for his work with PlayStation 4 exploits has turned his attention to the PS2. The motive for this exploration was to provide a "slightly more convenient" way to execute homebrew on the PS2 and also with the newer consoles being hacked via webkit exploitation and the PAL models Ps2 demo disc that contain Yabasic, the hacker seen the potential and now that potential has came to fruition with the release of this write up of exploiting a PS2 with Yabasic on a PS2 Demo Disc in PAL regions. The developer states in NTSC there may be a future solution (as mentioned in the conclusion of the writeup)Continue reading
[UPDATE] PS3HEN v2.4.0 - View latest changes to the PS3 Exploit for SuperSlims & nonCFW models4.85.1 HFW post by @Joonie
UPDATE (10-07-2019): Version 2.4.0 has been released.
See below for additional Details!
See also: The Great PS3 HEN All in One (AIO) Guide
Here is v2 of the latest PS3 Hack to hit the PS3 Scene with the recent release of PS3HEN. This exploit for nonCFW console's provides homebrew support and a number of Custom Firmware intangibles for those console that can not install a traditional CFW, with those being lat production PS3 Slim models and all of the SuperSlim Consoles. While this is a tremendous release and breakthrough the information behind PS3HEN has been lacking and has served more questions then answers that could be provided. This is due in the way this was delivered and presented. We paused the reporting this on the frontpage until we were pleased with the documentation. So we took it upon ourselves to get the ball rolling on a new PS3HEN F.A.Q. detailing various aspects and info that will be useful for PS3HEN user's. Also we have started forming the PS3HEN Homebrew & Plugin Compatibility Chart
Version 2.x.x has come with a number of new additions for a better experience. Some of the new changes provide full PS3ISO Support ,As well as full BDISO and DVDISO support has been added, plus new improvements to PS3HEN's stabiliContinue reading
