Note: This is by no means complete. Maybe there will be more parts down the road with more information as I learn them. Lots of it here is just info I gathered on the internet myself or learned by experimenting. So.. no TLDR :/

Update February 2020

The original Dockerfile used base image Ubuntu 17.10 which since then went EOL. I've updated it to use Ubuntu 18.04 LTS so compiling works again. Please update your sources.

Info

To even get started using this "guide" you have to have a jailbreakable PS4. At time of writing this is the PS4 System firmware version 5.05 because we are gonna use a OpenSource SDK for the PS4 which is (right now) only available for the Firmware 5.05 (or older) and a public available Kernel Exploit for the PS4.

Whats a kernel exploit?

Basically this triggers the PS4 into thinking its a debug machine - which will then allow code execution.

Setting everything up

We will set it up using a enviroment inside a docker container. If you don't want that, you can obviously just let it all run on your machine without virtualisation. First are the links we're gonna use inside a docker container, then I will show you how I ended up virtualizing all this by using docker.

• https://github.com/psxdev/ps4sdk/tree/firmware505 - Open Source SDK for PS4 Firmware 5.05
• https://github.com/orbisdev/liborbis - Libraries and samples /w the Open Source SDK
• https://github.com/psxdev/ps4link - We're gonna use this to "talk" to the PS4 and by injecting our own code. This is obviously just for debugging, later on you could compile your code to a single package.

And here is my docker solution (which I just forked, thanks again https://github.com/ooPo/ps4sdk-docker) on Github: https://github.com/pquerner/ps4sdk-docker.

You start by cloning the repository and then building the image.

Important: Make sure you open the Dockerfile in a texteditor and change the local ip address of your PS4. This is important because ps4sh will be compiled to target that ip address only.

This will take some time as it will compile the SDK and other tools for you. Depending on your machine it can take up to 30 minutes.

git clone https://github.com/pquerner/ps4sdk-docker.git
cd ps4sdk-docker
docker build --rm==false -t ps4sdk-docker .

After thats done, the enviroment is set up and you can start by compiling examples found in this repository https://github.com/orbisdev/liborbis/tree/master/samples. We'll get to that in the next step.

• [x] SDK installation
• [ ] Write and compile first own code
• [ ] Execute on PS4

Write and compile first own code

Now that we have the proper tools to build our tools against an SDK, we shall do so! For this blog post however I use a pre existing example which can be found in the liborbis repository I mentioned earlier. Also I assume you copied the helper script ps4sdk-docker.sh to your $PATH variable to easier access it. So, clone the liborbis repository and cd into a samples folder. I use the "starfield" demo.

git clone https://github.com/orbisdev/liborbis.git
cd liborbis/samples/starfield
ps4sdk-docker.sh make

The command "make" runs the Makefile inside the starfield folder - within the docker container.

After its compiled you'll find 2 new folders: bin and build. The bin folder actually contains the build homebrew.elf - ready to get send to the PS4!

-rwxr-xr-x 1 root   root   666K Mär 13 21:10 homebrew.elf

Now that we build injectable .elf file we can go to the next step - running it on the PS4.

Note: Some samples try to load media assets. If the assets are not found within the correct folder from where you are sending the homebrew.elf, the app will do nothing and simply show you a blackscreen on your TV screen.

• [x] SDK installation
• [x] Write and compile first own code
• [ ] Execute on PS4

Execute on PS4

We're gonna use the tool ps4sh to "talk" to the PS4 and inject our compiled homebrew.elf with the help of the tool orbislink.

Note: To my knowledge homebrew.elf is hardcoded within orbislink. Therefore you should just stick with that name and dont rename that file. Else it might not work.

First download and install orbislink on your PS4. Bring your PS4 into debug mode (you should know how) and install it.

At time of writing the orbislink tool was released with a hardcoded "server" ip address, therefor the computer you run ps4sh from must have the ip address 192.168.1.3. Best way to do this is give your machine manually the ip address. Either on the machine itself (must disable DHCP for this) or in your router. Consult your routers handbook or the internet.

sh into the docker container by calling the helper script: ps4sh-docker.sh (again, assuming thats in your $PATH or you are within the docker repository directory).

Within the docker container there are several aliases you can use. Consult the Dockerfile or README.txt to get to know them. Copy all needed assets (for example the starfield demo uses an asset called zweifeld.mod - which is a audio file. (I added it to the repository in case you cannot find it on the internet, its just a audio file so you could use a different audio, convert it to .mod and rename the file - or change the filename in the main.c or completely disable that line and recompile it) --> https://github.com/orbisdev/liborbis/blob/2e67a9b9111345bb6aec1dd15b533d50faecd055/samples/copperbars/source/main.c#L258) and the homebrew.elf to the PS4SH directory inside the docker container. (Alias elfcp and enviroment variable $PS4SH may help you.).

This is how my ps4sh directory looks like with the starfield demo:

root@honeycomb:/usr/local/ps4dev/ps4link/ps4sh/bin# ls -lah
total 772K
drwxr-xr-x 1 root root 4.0K Dec 30 01:59 .
drwxr-xr-x 1 root root 4.0K Dec 30 01:59 ..
-rwxr-xr-x 1 root root 666K Dec 30 01:59 homebrew.elf
-rwxr-xr-x 1 root root  59K Dec 30 01:59 ps4sh
-rw-r--r-- 1 root root  34K Dec 30 01:59 zweifeld.mod

Start ps4sh (with alias ps4sh is quickest).

You should see ps4sh started and waiting for commands:

root@honeycomb:~# ps4sh
ps4sh version 1.0

If everything worked correctly, you shouls see the demo running on your PS4 - the ps4sh shell might also hint you when somethings not right.

That blog post now concludes how you can execute own code on your ps4 with the help of an OpenSource SDK.

Good luck and show me your results sometime! :)

• [x] SDK installation
• [x] Write and compile first own code
• [x] Execute on PS4
