How to: N64 Emulation on Bazzite using Mupen64Plus

mupen64plus-bazzite.sh

# This guide explains how to run Mupen64Plus on Bazzite, without any
# extra stuff like retroarch or RMG.
#
# You should only follow this guide if you have already tried RetroArch
# and/or RMG. I highly recommend trying RMG first:
#
#        https://flathub.org/en/apps/com.github.Rosalie241.RMG
#
# If RMG isn't working for you, this guide will walk you through setting
# up a bare Mupen64Plus installation straight from the source.

###########################################################################

# 1. Download the latest release of Mupen64Plus from their official GitHub:
#
#        https://github.com/mupen64plus/mupen64plus-core/releases
#
#    At time of writing, the latest version is 2.6.0.
#    You're looking for a file named:
#
#        mupen64plus-bundle-linux64-<VERSION>.tar.gz 

VERSION="2.6.0"

wget "https://github.com/mupen64plus/mupen64plus-core/releases/download/$VERSION/mupen64plus-bundle-linux64-$VERSION.tar.gz"

# 2. extract the tar file, and run the installer script:

tar xzvf "mupen64plus-bundle-linux64-$VERSION.tar.gz"
cd mupen64plus-bundle-linux64-$VERSION
sudo ./install.sh

# 3. a couple extra libraries are needed, which you can install through brew:

brew install speex speexdsp

# 4. add the homebrew libraries to LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=/home/linuxbrew/.linuxbrew/lib/:$LD_LIBRARY_PATH

# 5. I also had to symlink the libmupenplus.so file to make it work:

sudo ln -s /usr/local/lib/libmupen64plus.so.2.0.0 /usr/local/lib/libmupen64plus.so.2

# 6. launch mupen64:

mupen64plus \
    --fullscreen \
    --audio mupen64plus-audio-sdl \
    '/path/to/your/rom.z64'
