PlayStation PSP Compilation / Development Guide¶
You need the homebrew PlayStation PSP SDK and toolchain installed.
Clone RetroArch's repository from GitHub
git clone https://github.com/libretro/RetroArch.git retroarch cd retroarch
For subsequent builds you only need to pull the changes from the repo
cd retroarch git pull
To update your local copy from the repository run git pull
Building RetroArch separately¶
First, you need to compile 'Salamander'. To compile Salamander (for PlayStation Portable) run:
make -f Makefile.psp1.salamander
Second, to compile RetroArch (for PlayStation Portable) run:
make -f Makefile.psp1
RetroArch on PlayStation PSP is statically linked. With statically linked RetroArch, each executable is a separate libretro core instead of the core being separately loaded from a single executable. A pre-existing libretro library needs to be present in the root directory in order to link RetroArch Vita. This file needs to be called 'libretro_psp1.a'.
After a few seconds/minutes you should be able to find a retroarch_psp1.elf and retroarch_psp1.self file under that directory.
Building RetroArch in bulk¶
Instead of building each core one by one, you can build all cores as a batch task. Run from the main 'retroarch' directory:
Make sure that all the libretro cores that you want to compile are inside the 'dist-scripts' directory.
Once inside this directory, run :
This process will also automate the packaging process for you.
The easiest way to fetch all the cores is to use libretro-super. Run
The easiest way to build all the cores (for PlayStation Portable) is to use libretro-super. Run
In case you only want to build one and/or more cores instead of all, you can specify the cores you want to build after the first command in no particular order. E.g.:
./libretro-build-psp1.sh snes9x2010 fceumm
Once finished, you can find the libretro cores inside directory
