 notes: |
+  The libretro build is WizzardSK's rpcs3-libretro, which the buildbot builds
+  from libretro/rpcs3-libretro on git.libretro.com. It carries RPCS3's
+  emulation code merged up to ab412d5d (rpcs3/libretro/upstream.version) and
+  keeps its config, caches, dev_hdd0 and dev_flash under system/rpcs3/
+  (rpcs3/libretro/libretro_core.cpp:1880-1893, 1925-1936). The PUP is found
+  and installed by the core itself, with no prompt, and the game database,
+  patches and vblank unlock list are embedded in the binary
+  (rpcs3/libretro/CMakeLists.txt:16-28).
+
   RPCS3 requires the official PS3 firmware (PS3UPDAT.PUP) from Sony. The PUP file is
   a signed update package containing multiple TAR archives prefixed with "dev_flash_".
   During installation, RPCS3 extracts these TARs into the dev_flash/ directory structure.
