libretro/ppsspp answers as libretro-mirrors/ppsspp-old, a 2020 tree frozen in 2022. The buildbot builds ppsspp from hrydgard/ppsspp master, whose libretro/ directory holds the wrapper, so the profile is read again at 58935bbf and pinned there. The asset directory, PPGe atlas and font lookup are cited where they sit now. The notes record the NAND under the save directory that a disc's firmware updater fills, and the modules it replaces.

|
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: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).
