notes: |
  Full HLE emulator. No Sony firmware or BIOS required.
  The libretro core is built from hrydgard/ppsspp, the tree of the
  standalone emulator, with its wrapper in libretro/.
  Libretro core loads assets from system/PPSSPP/ via VFS
  (libretro/libretro.cpp:1216-1225, 1271) and warns that core system files
  are missing when compat.ini is absent (libretro/libretro.cpp:1229-1261).
  Assets include replacement PGF fonts (flash0/font/),
  game compatibility database (compat.ini), language mapping (langregion.ini),
  and post-processing shaders (shaders/).
  Fonts are read from the game disc, then from flash0:/font of the NAND,
  then from flash0/font/ in system/PPSSPP/ (Core/HLE/sceFont.cpp:1026-1048).
  Without any of them the font library holds no internal font and
  sceFontOpen returns SCE_FONT_ERROR_INVALID_PARAMETER to the game
  (Core/HLE/sceFont.cpp:1197-1199), so text a game draws with the PSP system
  fonts is lost. Without ppge_atlas.zim the system dialogs are not drawn
  (Core/Util/PPGeDraw.cpp:252-255).
  A real firmware is optional. The NAND is <memstick>/PSP/NAND
  (Core/Util/PathUtil.cpp:146-147), which the libretro core places under
  the save directory (libretro/libretro.cpp:1265, 1269). On boot, a game
  disc carrying a newer firmware updater than the installed one is
  unpacked into it (Core/System.cpp:591-594). Its flash0:/font,
  kd/libmp4.prx, kd/mp4msv.prx and kd/mpeg.prx replace the HLE modules
  when present (Core/HLE/HLE.cpp:408-446).
  PSP_DEFAULT_FIRMWARE = 660 (Core/ConfigValues.h:40).
