Utilities for getting Celeste to work with FMOD 2 on ARM64 and x86_64 Linux. Tested on Switch with Ubuntu Noble 24.04. It also automatically install Everest mod.
Installation
These steps are meant to be followed directly on the Switch. You don't need a separate Linux system. (For your convenience, you may also choose to perform these operations over SSH. If you do, make sure to set DISPLAY=:0 and WAYLAND_DISPLAY=wayland-0 before attempting to start Celeste.)
Download Celeste from either itch.io or Epic Games Store. Download the Linux build if possible (but Windows FNA builds may also work). Builds on Steam will not work because the Steam version of the game contains DRM.
Download the latest release of Celeste-FMOD2 and extract it somewhere other than the Celeste folder.
Run the following commands in the terminal.
cd /path/to/Celeste-FMOD2 ./patch.sh /path/to/celeste-linux/Celeste.exe
If the patcher was successful, run the following commands. You may be required to enter your password. After running these command, the installation will be complete and Celeste will start.
cd /path/to/celeste-linux ./Celeste-fmod2
You should now be able to launch Celeste using the app launcher.
Note that if you decide to move the Celeste folder somewhere else in the future, you'll have to run /path/to/celeste-linux/Celeste-fmod2 again to fix the app launcher shortcuts.
Mods
Celeste-FMOD2 will install Everest automatically. However, Olympus isn't available on the Switch, so you'll have to manually download mods and copy them into the Celeste folder.
