  Libretro port of Open Syobon Action (Cat Mario), the SDL port of the
  Japanese platformer by z_gundam_tanosii. Game assets required in
  system_dir/SyobonAction/ with BGM/, SE/, and res/ subdirectories.
  Level data hardcoded in source. The original libretro/syobonaction-libretro
  repo was deleted; source points to the archived original by iyzsong.
  The .info display_version is "0.1" but the code reports "0.3".
