  Somewhat Interactive Nostalgic Game Engine by Scott Duensing, the Lua
  laserdisc game engine, released as v2.10 on 2024-03-26 (CHANGELOG). The
  program is GPLv3 but no public source tree was reachable, so this profile
  reads the Windows binary RetroBat installs, Singe-v2.10-Windows-x86_64.exe
  (sha1 5a4883ff55da7d4690a8763e6f3ff443ec1d5293).

  emulatorlauncher links the game folder next to the executable and runs
  `Singe-v2.10-Windows-x86_64.exe -k -w|-x -y [-z] [-n] -v <video> <script>`,
  taking the video and the .singe script from the game's .dat, .game or
  folder layout. Its ActionMax mode looks for an ActionMax folder in the
  package (emulatorLauncher Generators/Singe2.Generator.cs:24-150).

  The video and the script arrive on the command line and the program stops
  with "Unable to locate video." or "Unable to locate script." when either is
  absent. Everything else it opens it carries itself. Framework.singe,
  Menu.singe, FreeSansBold.ttf, menuBackground.mkv and controls.cfg.example
  are byte arrays in the executable (Framework_singe, Menu_singe and so on in
  its symbol table), written out to Singe/ with ">>> Created File:" when
  missing. The framework is run with dofile("Singe/Framework.singe") and
  sets SINGE_FRAMEWORK_VERSION 2.10.

  controls.cfg is looked up in the script's folder and in the folder above
  it, and when neither holds one the built-in mappings apply ("Loading default control
  mappings"). Files the engine writes go to the data directory given by -d.
  The KarisFramework, KimmyScript and Blank folders RetroBat ships are Lua
  libraries and a sample game that game scripts load by path, not files the
  engine opens.
