PSPDEV is an open source toolchain for Playstation Portable development. It allows you to make apps and games for both custom and official firmwares. This is a community project made by enthusiasts, it is in no way affiliated with Sony.
The PSPDEV toolchain requires a couple of dependencies to be installed before use.
On Windows it is advised to use Ubuntu on Microsoft's WSL system. To set it up run the following commands in a Powershell window started as administrator:
wsl --install
Now run bash and run the following commands to instal the dependencies:
sudo apt-get update
sudo apt-get install build-essential cmake pkgconf libreadline8 libusb-0.1 libgpgme11 libarchive-tools fakeroot
Going forwards, all commands will be run within bash. The filesystem of your Ubuntu installation can be accessed by opening the network location ``\wsl$`.
On Ubuntu run the following commands to install the dependencies:
sudo apt-get update
sudo apt-get install build-essential cmake pkgconf libreadline8 libusb-0.1 libgpgme11 libarchive-tools fakeroot
On MacOS make sure to install Brew first, then run the following commands to install the dependencies:
brew install cmake pkgconf gnu-sed bash openssl libtool libarchive gettext texinfo bison flex gsl gmp mpfr
To install the PSPDEV toolchain, first download the latest version for your system. Extract it into your user's home directory, which would be \\wsl$\home\username on Windows, otherwise ~. If you're on Windows, pick the Ubuntu build.
Now set the required environment variables. On Mac edit the ~/.bash_profile on Linux/WSL the ~/.bashrc file. Add the following at the bottom:
export PSPDEV=~/pspdev
export PATH=$PATH:$PSPDEV/bin
This can simply be done with nano ~/.bashrc. To save press Ctrl+X, then press y, then enter/return twice. After that run source ~/.bashrc to apply the changes.
That's it, now the PSPDEV toolchain can be used to build PSP software. Below are some examples of programs and how to run them. For testing on real hardware, check out psplink.
Below are some basic examples of programs for the PSP. More can be found here.

SDL2 is a library which handles system specific things like input, audio and window management for you. It can also be used to render shapes and images, just like the native libgu. This will be slower, but will result in code that can be run more easily on multiple platforms. Click on details below for the to see the code and how to build it.

This will result in an EBOOT.PBP file in the build directory. Put it in a directory in ms0:/PSP/GAME/ and you need an audio file to test the program, download it from here. Put it in a directory in ms0:/MUSIC/ and then rename the audio file same as name on your MUSIC_PATH macro in your C code and the PSP can run it.

Building can be done with:
mkdir build && cd build psp-cmake .. make
This will result in an EBOOT.PBP file in the build directory. Put it in a directory in ms0:/PSP/GAME/ and you need a font file to test the program, download it from here. Put it in a directory same as EBOOT.PBP and the PSP can run it.
Here some useful tips for developing for the PSP.
The PSPDEV toolchain contains tools for making your program work on unmodded PSPs. This can be done by running psp-cmake with some additional commands when building like so:
mkdir build && cd build
psp-cmake -DBUILD_PRX=1 -DENC_PRX=1 ..
make
This does require create_pbp_file to be used in your CMakeLists.txt file. After the first build, running make is enough to get an EBOOT.PBP file which works on official firmware with any new changes made to the code.
When porting a game to the PSP, some PSP specific code might be needed. To make this code only apply to PSP, it is possible to use a simple ifdef statements which checks for __PSP__ like so:
#ifdef __PSP__
// Do PSP specific thing
#else
// Do the thing all other systems should do
#endif
This makes sure that the other systems supported by the program keeps working the same, while still making it possible to add support for the PSP.
There are many C and C++ libraries available within the PSPDEV toolchain which can add functionality to your program. Some examples:
- Audio formats: mp3, ogg
- Image formats: png, jpeg
- Data formats: json, yaml, sqlite
- Support for compression, physics, fonts and much more
For the full list take a look at the psp-packages repository or run psp-pacman -Syl. Updating libraries can be done with psp-pacman -Syu.
