+  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.
