Building Godot 3.5 for Nintendo Switch

These steps must be done under Linux / Windows Subsystem for Linux (WSL) or MSYS2 on Windows.

Dependencies

If you haven't done so already, install the dependencies called for by the official Godot docs

Install devkitPro pacman or add DKP to your existing pacman configuration:

Install the required packages from the terminal

# On systems without pacman pre-installed (Such as Debian, Ubuntu):
sudo dkp-pacman -S switch-pkg-config switch-freetype switch-bulletphysics switch-libtheora switch-libpcre2 switch-mesa switch-opusfile switch-mbedtls switch-libwebp switch-libvpx switch-miniupnpc switch-libzstd switch-wslay

OR

# On systems with pacman pre-installed (Such as Arch, Manjaro, MSYS2):
sudo pacman -S switch-pkg-config switch-freetype switch-bulletphysics switch-libtheora switch-libpcre2 switch-mesa switch-opusfile switch-mbedtls switch-libwebp switch-libvpx switch-miniupnpc switch-libzstd switch-wslay

Getting the source code

Clone the repo
git clone https://github.com/Homebrodot/Godot
Navigate to the cloned repo
cd Godot
Checkout the main/3.5 branch
git checkout origin/main/3.5

Building

Run scons platform=switch in the root of the repo.
Add target=release to the end to build for release instead of debug.
Run misc/scripts/build/create-switch-release.sh from inside the bin folder to create an installable release for your Switch.
Run misc/scripts/build/create-switch-template.sh from inside the bin folder to create an export template for your editor.

Exporting for Nintendo Switch

The editor releases add a Switch exporter to the list - it can generate a Switch homebrew NRO or a generic Godot PCK file that can be transferred to your Switch.

If additional debugging is required, sending the NRO file via nxlink (make sure to send it to the right place with the -p argument) will allow the output of the console to be viewed on PC.
