notes: |
  Azahar is the successor to Citra (via Lime3DS). Different codebase
  from libretro/citra — has additional files not in the old Citra.
  Data dir: azahar-emu (legacy: citra-emu, lime3ds-emu).
  ref: src/common/common_paths.h:41-47

  Key file: keys.txt (NOT aes_keys.txt like libretro/citra).
  ref: src/common/common_paths.h:83

  Uses RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY.
  ref: src/citra_libretro/environment.cpp:194

  .info has firmware_count=0 but core uses system_dir for files.
