This shouldn’t have been as hard as it was, but here it is. Please note you will need a Melee ISO ready before proceeding, and this guide will not cover how to make one

  1. Install Slippi from the Slippi website
  2. This will install an AppImage file, e.g. Slippi-Launcher-2.11.9-x86_64.AppImage. To run this, run the below commands:
./Slippi-Launcher-2.11.9-x86_64.AppImage --appimage-extract
sudo chown root:root squashfs-root/chrome-sandbox
sudo chmod 4755 squashfs-root/chrome-sandbox
./squashfs-root/AppRun

This will expand the AppImage into its own folder and give it the correct sandbox permissions to run.

I also ran into the below errors, resolved via other commands:

  1. Error running libfuse2.so

Resolved via the below command:

sudo apt update
sudo apt install libfuse2
  1. ] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_SlippiGo70xt/chrome-sandbox is owned by root and has mode 4755.

This was resolved using the chown and chmod commands listed in Step 2.

Optimizing Performance on Linux

This has been a challenge. Even now, I am still dropping frames despite having smooth performance on Windows and a powerful gaming PC with an AMD Ryzen CPU and NVIDIA RTX 3070 TI. It is mostly playable however. So far, what I’ve figured out:
