Orbital PS4 emulator for Windows – PC Desktop

Uploaded byBlowFlies


Orbital is a virtualization-based Play Station 4 Emulator for Windows and Linux that is under heavy development (see also MacOS, iOS and Android version). It can only boot the firmware. Do not expect to play commercial games with it yet. It is also open-source and is a low-level emulator.

Decryption with SAMU is “emulated” by hashing encrypted input blobs and returning decrypted blobs previously obtained from the actual console. No keys were dumped, no keys will be dumped. More importantly: we don’t need them, so this project does not target SAMU.

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.


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.

The experimental version is aviable on the link below.
