anchor: love.filesystem.isFused
  Gets whether the game is in fused mode or not.
  
  If a game is in fused mode, its save directory will be directly in the Appdata directory instead of Appdata/LOVE/. The game will also be able to load C Lua dynamic libraries which are located in the save directory.
  
  A game is in fused mode if the source .love has been fused to the executable (see Game Distribution), or if '--fused' has been given as a command-line argument when starting the game.
  fused = love.filesystem.isFused()
  fused boolean True if the game is in fused mode, false otherwise.
