Steam Deck non-steam game shortcut maker

shortcutMaker.sh

#!/bin/sh

# Creates shortcut ".desktop" files to facilitate easily adding non-steam games
# by Aelius

# NOTES
# Linux GOG games installed by GameHub create their own shortcuts
  # This is not true for Heroic nor MiniGalaxy
  # They attempt to create shortcuts, but currently not working in flatpak
# GameHub flatpak cannot currently install Windows games without innoextract
  # So I'm using GameHub for linux GOG and win/linux itch.io
  # Heroic for Windows GOG and Epic
# Script assumes Windows-only for Heroic installs
# Script assumes linux-only for itch.io installs
# Script assumes itch.io games are installed to ~/Games/itch (this is the default for GameHub)

# TODO
## Search for itch.io in default install location
## Search for linux installs in Heroic
## Search for Windows installs in itch GameHub 
## Support minigalaxy
## Unique name per shortcut, in case there are multiple installs of the same game
