Nintendo Wii Compilation / Development Guide¶
You need the homebrew Nintendo Wii SDK libogc and Devkitpro PPC 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'. Salamander is the RetroArch frontend for embedded platforms for which the cores are statically linked to the frontend. It means that for each core there is a file which contains the code of the core and the frontend.
To compile Salamander (for Wii) run:
make -f Makefile.wii.salamander
Rename the file retroarch-salamander_wii.dol as boot.dol. This file is the frontend launcher for the other cores (indeed files containing core and fronend).
Second, to compile RetroArch for Wii (the core and the frontend), rename the compiled core as 'libretro_wii.a' (see bellow how to compile a core), put it in the RetroArch directory and run:
make -f Makefile.griffin platform=wii
RetroArch on Wii 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 Wii. This file needs to be called 'libretro_wii.a'.
After a few seconds/minutes you should be able to find a retroarch_wii.elf and retroarch_wii.dol 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. Download libretro-super from github and run
The easiest way to build all the cores (for Wii) is to use libretro-super. If not already fetched, put the codes of the cores you want compile in the libretro-super directory and 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-wii.sh snes9x2010 fceumm
Once finished, you can find the libretro cores inside directory
