libretro: PPSSPP

Technical notes

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/), game compatibility database (compat.ini), language mapping (langregion.ini), and post-processing shaders (shaders/). Libretro fork (2020-03-18) behind upstream. PSP_DEFAULT_FIRMWARE = 660 (Core/ConfigValues.h:40).
