retroarch (1.8.5) install a libretro core (ppsspp_libretro.so) in /usr/local/lib/libretro/ which is the default defined path in libretro_directory (retroarch.cfg) - it seems that ppsspp should be part of the libretro-* ports - libretro_directory should be /usr/local/libexec/libretro as used by the libretro-* ports
(In reply to sdalu from comment #0) > libretro_directory should be /usr/local/libexec/libretro as used by the libretro-* ports Nah, it's the opposite: libretro-" should use the 'lib' path, and the maintainer of these parts is already working on this in Bug 246067. 'lib' is the default in current retroarch. Because, uhh, the cores are loadable libraries, not executables :) > it seems that ppsspp should be part of the libretro-* ports libretro-* ports are forks under the retro org on GitHub. the ppsspp port is upstream PPSSPP. It supports libretro in the upstream project. mgba does that too.
