The PSP Software Development Kit (PSPSDK) is a collection of Open Source tools and libraries written for Sony's Playstation Portable (PSP) gaming console.

It also includes documentation and other resources developers can use to write software for the PSP.

Features

• Stub libraries and headers for interfacing with the PSP operating system, ranging from threading libraries, file io, display driver and Wifi networking.
• Basic runtime support (crt0) for executables and libraries.
• A minimal port of the Standard C Library (libc) is included. PSPSDK's mini-libc provides portable memory allocation, string formatting, and several other Standard C Library functions.
• Support code for linking with the full Standard C Library provided with the PSPDEV toolchain.
• An implementation of the libGU graphics library. libGU provides an interface to the 2D and 3D hardware acceleration features found in the PSP's Graphic Engine.
• An implementation of the libGUM library. libGUM provides an interface for manipulating matrices for use in 3D software.
• A simple audio library which can be used to play back PCM audio streams.
• Support for building static executables and PRX files (relocatable modules).

Installation

Requirements

PSPSDK is distributed in both source and binary packages.

If you only want to use the PSPSDK tools and libraries to develop your software you'll want to grab the binary distribution of PSPSDK specific to your development platform.

If you need fine-grained control over how PSPSDK is installed on your system, or if you would like to modify PSPSDK then grab the source distribution. You can also install PSPSDK from Git, see "Installation from Git" below for details.

To use PSPSDK you must have the following software installed:

• The PSPDEV Toolchain. PSPSDK requires the GNU toolchain (GCC and binutils) targetted to the PSP.
• You can find binary packages of these tools at https://github.com/pspdev. You can find a script to build and install thetoolchain.

In addition to the above requirements, if you plan on building PSPSDK from source, you will need:

• Make (Note: GNU Make may not be required, but if you run into problems building from source you may want to install it).

If you plan on building PSPSDK directly from the Git repository you will need:

• A Git client. A popular client for Windows is TortoiseGit.
• GNU autotools. You will need a recent version of autoconf and automake.

The following packages are not required to build PSPSDK, but are used to build documentation and other optional resources:

• Doxygen.

If you want to view the pretty source dependency graphs, then you will also need to install:

• Graphviz.

Installing from binary

Download the PSPSDK binary package specific to your development system.

For example, if you are using Windows, you will want to download the file pspsdk-1.0-win32.zip.

Extract or unzip the package into the folder where the PSPDEV toolchain is installed. For example, on a Windows system you may have installed the PSPDEV toolchain to C:/pspdev. You would then unzip PSPSDK into C:/pspdev.

Update your PATH environment variable to point to the PSPSDK tools directory.

In the above example, if you installed PSPSDK to C:/pspdev, you would add C:/pspdev/bin to your path.

Installing from source

PSPSDK uses the GNU autotools (autoconf and automake) for its build system. To install PSPSDK from a source distribution, run the following commands after unpacking it:

./configure
make
make doxygen-doc
make install

If you haven't installed Doxygen or don't want to build the library documentation, you can skip the third step.

Installing from Git

PSPSDK can be found in the Git repository located at https://github.com/pspdev/pspsdk. If you are using the command line version of the git client, you can the following command to download PSPSDK:

git clone https://github.com/pspdev/pspsdk.git

Once you've downloaded PSPSDK, run the following from the pspsdk directory to create the configure script and support files (you must have autoconf and automake installed):

./bootstrap

You can now run the commands listed in the "Installation from source" section.

User guide

PSPSDK also provide some additional tools that assist in building PSP software:

• bin2c, bin2o, and bin2s for converting binary files into C source, object files, and assembler source files, respectively.
• mksfo for creating PARAM.SFO files.
• pack-pbp and unpack-pbp for adding files to and removing files from EBOOT.PBP.
• psp-config for locating PSPDEV tools and libraries.
• psp-prxgen for converting specially made ELFs to PRX files.
• psp-build-exports for creating export tables
• psp-fixup-imports for fixing up import tables post-linking to remove unused functions from the executable.

Documentation for the libraries are also provided, and can be found in the doc/directory of the PSPSDK source and binary distributions.

A library for Make (build.mak) is also included to provide an easy way to build simple programs and libraries. See any PSPSDK sample program for details on how build.mak is used.

Note: By default PSPSDK will install into the directory where the PSPDEV toolchain is installed. If you decide to install PSPSDK somewhere else then you must define a PSPSDK environment variable that points to your alternate directory.

The psp-config build utility will look for PSPSDK in the location specified in the PSPSDK environment variable first, or use its own location to determine where PSPSDK is installed.

The Makefile templates provided by the sample code are designed for building a single executable or a library, but not both. If you plan on using these templates in your project to build both libraries and executables be aware that you will have to structure your project so that each library and executable are built in a seperate directory.

Credits

The pspsdk developers wish to thank all the people who have contributed bug fixes, ideas and support for the project. Also big thanks to nem for kicking off PSP development with all his work, the original imports system is based on his work in the hello world demo.
