Following his previous Nucleus PS3 / PS4 PC emulator project, PlayStation 4 developer @AlexAltea (Twitter) recently kicked off a virtualization-based PS4 emulator called Orbital on Github with help from some other scene devs.

Keep in mind it's currently in the early stages and not ready for end-users, but they do have future plans for the emulator outlined for those following its progress.

Download: orbital-master.zip / GIT

To quote from the README.md: Orbital

Virtualization-based PlayStation 4 emulator.

Status

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.

FAQ

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...

Today MeTheKing let us know (thanks to mtnjustme for testing) of a few useful Python scripts recently released by n1ghty, specifically PKG_List which is a PKG list generator and also PKG_Rename which -as you guessed- is a PKG renamer for PS4 package files based on UnPKG by @flatz.

Download: pkg_list-v100-bin.zip (3.4 MB) / pkg_list-v101-bin.zip (3.4 MB) / PKG_List (Latest) / PKG_List GIT / pkg_rename-v100-bin.zip (3.1 MB) / PKG_Rename (Latest) / PKG_Rename GIT / PKG_Tools (Latest) / PKG_Tools GIT

From the README.md, to quote: pkg_list

PKG list generator for PS4 pkg files by n1ghty

This file is based on

• UnPKG rev 0x00000008 (public edition), (c) flatz
• Python SFO Parser by: Chris Kreager a.k.a LanThief

This tool parses all pkg files in the specified directory/directories recursively and then generates an excel sheet from the parsed infos.

Usage

python pkg_list.py <paths to pkg directories>

e.g.: python pkg_list.py "D:\PS4_pkgs" or python pkg_list.py "D:\PS4_pkgs" "E:\second_pkg_directory" "C:\third_pkg_directory" or for current directory: python pkg_list.py.

pkg_list v1.01 Changelog:

• added recursive directory parsing
• fixed file ending case sensitivity

And from the other README.md, to quote: pkg_rename

PKG renamer for PS4...

Earlier this week we saw a PS4 homebrew game port of Roll A Ball / Roll The Ball PKG, and today PlayStation 4 developer @LightningMods returns with a PS4 4.55 Homebrew W.I.P. (work in progress) package via Twitter for other developers to examine and eventually use as a template to build upon when he releases the requested source code.

Some screenshots are below, and to quote from his Tweet embedded below: Hello im releasing "4.55 Homebrew W.I.P" Not fully done its a W.I.P but here it is.

Also below is a PS4 System RW payload for 4.55 ONLY in the form of FTP+RW.bin, however, it comes with a WARNING to use CAUTION if you decide to give the unsandboxed FTP access and re-mount ALL system partitions as RW payload a try.

It can permanently brick your PS4 so don't use it if you don't know what you're doing and aren't willing to take the risk!

Download: PS4-System-RW-master.zip / GIT

And from the README.md file for those interested: PS4-System-RW

This Payload gives you Unsandboxed FTP Access and re-mount ALL System Partitions as RW (USE CAUTION) on FW 4.55 ONLY!

Release Features

1. FTP Access (root)
2. Read and Write to the following partitions

• /system_ex
• /system_tmp
• /preinst
• /preinst2
• /dev (sometimes works)
• Some others i might have forgot

3. Optimized for use with a HEN (No Freezing!)

Following his PS4 NID to Function Name Resolver, PlayStation 4 developer Zer0xFF shared news of a new project he's involved with focusing on PS4 OpenGL ES2 hardware accelerated graphics rendering.

Below is an introduction excerpt, with the full details posted on his blog at Blog.MadNation.net for those interested:

"So a while back I found a reference to OpenGL ES (GLES) in one of the PS4 libraries libScePsm.sprx which peeked my interest, you see OpenGL is a widely adapted 2D & 3D rendering solution and having access to it, on the PS4, would make porting over emu, games and even building nice UI for games/homebrew and such much easier, not only that it also means we'll have access to hardware accelerated graphics rendering.

The blog won't be all that technical, but it will just walk you through our attempt to get GLES to work, while progress has been made, we still haven't managed to get OpenGL ES to work, well not to a useful state atleast.

Quick Thanks to @masterzorag for the help with the reverse engineering and since he had the hackable console he did all the testing."
