notes: >-
  Libretro core wrapping Panda3DS, an HLE Nintendo 3DS emulator.
  Shared font, Mii data, country list and bad word list are embedded in
  the binary via CMRC and compiled-in headers. DSP firmware is loaded from
  the game ROM at runtime, not from an external file.
  DSP modes: HLE (default), LLE (Teakra), Null.
  Files are resolved from the RetroArch save directory
  (<save_dir>/Emulator Files/sysdata/), not the system directory.
