PSL1GHT is a lightweight PlayStation 3 homebrew SDK that uses the open-source PlayStation 3 toolchains to compile user applications that will run from the XMB menu (GameOS homebrew).

A GCC toolchain that supports the PowerPC 64bit architecture is required to build PSL1GHT and its samples. It also requires the toolchain to provide a full newlib environment; at the moment only two toolchains do so:

The SDK also includes a few standalone tools to help compilation. A host gcc is required to build raw2h, ps3load, and sprxlinker requires libelf. ps3load requires zlib installed. Python 2.x is required to run,, and Nvidia's cg toolkit (found here, or check your distro's repository) is reqired for compiling vertex programs.

Most of the PSL1GHT samples included in the samples/ directory require various libraries from ps3libraries to be installed.


Run make install in the psl1ght directory to build it all, and make sure to set the environment variable $PSL1GHT to the folder where you wish to install it to, for example...

cd /path/to/psl1ght.git/psl1ght/
export PSL1GHT=/path/to/psl1ght.git/psl1ght/build
make install

... for a local build of it. Ensure that $PSL1GHT is set when you are building any of the examples or other apps that use PSL1GHT.

Current Status


PSL1GHT supports hardware acclerated 3d graphics. Vertex shaders are a work in progress and Fragment shaders don't exsist yet.


PS3 controllers are fully supported, and pressing the PS button brings up the in-game XMB menu, assuming the framebuffer is working.

But you can't currently quit from the xmb without your ps3 giving up and rebooting.

Filesystem Access

Full filesystem support is available, with access to the internal PS3 hard drive, game disc contents, and external devices like USB drives. Only directory iteration is missing, though it can be done using the lv2 filesystem interface directly (see include/psl1ght/lv2/filesystem.h)


Berkeley sockets are available for use in PSL1GHT, though some of the implementation remains incomplete at this time (hostname lookups, for example).

STDOUT Debugging

By default, PSL1GHT applications redirect stdout and stderr to the lv2 TTY interface. Kammy's ethdebug module can be used to retrieve this live debugging information over UDP broadcast packets. See Kammy for more information and a precompiled ethdebug hook loader.


PSL1GHT provides access to running programs on the raw SPUs, and communication with it from the PPU. See sputest in the samples directory for a simple example.

SPRX Linking

Any dynamic libraries available to normal PS3 applications can be used with PSL1GHT, they just need to be made into a stub library and have the exports filled out. See any of the examples in psl1ght/sprx for information on the creation of SPRX stub libraries.

The following libraries are currently supported:

  • libio
    • libpad
    • libmouse
  • liblv2
  • libsysutil
  • libgcm_sys
  • libsysmodule
  • libpngdec
  • libjpgdec
