PS4 SDK

An open source PlayStation 4 SDK for writing userland applications which can be run with the PS4-playground.

Building and installing

You will need LLVM version 3.7 or later for compiling, and binutils for linking (from MinGW if you are on Windows).

Clone this repository locally, or download and extract a ZIP of the repository here.

Then create an environment variable called, PS4SDK which points to the base directory of the repository, using the Unix path style; for example:

/C/Users/Chris/Documents/GitHub/PS4-SDK

Build the libraries by running make on the libPS4 and libusbfatfs directories.

Finally, you can build examples by running make on them.

Design

At the moment, it is primarily focused on system calls.

However, using function pointers and the RESOLVE macro, we can call functions from other modules. For example, the socket functions from libSceNet.sprx.

Support

Whilst the SDK isn't capable of most basic functionality yet, such as displaying graphics, or receiving controller input, there are workarounds: rendering to an HTML5 canvas, and using third party USB controllers, or a DS/PSP wirelessly for example.

The SDK is currently in a state where projects like an FTP server, a mini Pong game, or GameBoy emulator could be developed.

Examples

hello - Load libc module and perform getpid system call

sockets - Send a message over a TCP socket

modules - Load and dump a module

threads - Create and wait for a thread to increment a variable

canvas - Render to an HTML5 canvas

camera - Initialise the PlayStation Camera and capture 10 frames

pad - Read controller input (not finished)

jit - Setting up JIT shared memory

Filesystem

directories - List the contents of a directory

files - Read a file's size, and its contents

USB

list_devices - List information about all USB devices connected

storage - Read raw image from a USB flash drive

usbfatfs - Read files from USB formatted with FAT
