   An addon whose dependency is not found is removed from the list

+  The libretro build is the same tree at ec5824db with platform/Libretro/
+  added and the file access routed through the frontend VFS. The content
+  is a GRP, ZIP, PK3 or PK4 opened by full path
+  (platform/Libretro/core.cpp:615-623). It is mounted as the first group,
+  and the folder that holds it is the search path the core adds
+  (platform/Libretro/core.cpp:652-670). G_AddSearchPaths is never called.
+  The scan then runs over that folder and keeps the GRP named DUKE3D.GRP, else the first one it
+  recognises, which sets the game type and its CON, DEF and RTS names
+  (source/duke3d/src/common.cpp:339-358, 420-443). Every file below is
+  therefore read beside the content, never from the system directory.
+  Relative paths, the config and the GRP cache among them, resolve below
+  the save directory (platform/Libretro/core.cpp:486-489,
+  platform/Libretro/vfs_libretro.cpp:31-40).
