   Full HLE emulator. No Sony firmware or BIOS required.
-  All PSP kernel modules (flash0:/kd/*.prx) are reimplemented in C++.
-  Libretro core loads assets from system/PPSSPP/ via VFS.
-  Assets include replacement PGF fonts (18 files in flash0/font/),
+  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/).
-  flash0/ is read from system/PPSSPP/flash0/ (libretro/libretro.cpp:546).
-  Without its fonts the font library holds no internal font and
-  sceFontOpen returns ERROR_FONT_INVALID_PARAMETER to the game
-  (Core/HLE/sceFont.cpp:805-864, 984-986), 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:227-230).
-  Libretro fork (2020-03-18) behind upstream.
+  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:144-145), 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:575-578). 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).
