"""Flycast's two builds read the same files from two directories.

The libretro port looks in <system>/dc/ (shell/libretro/libretro.cpp:2249-2250).
The standalone emulator looks in its data directory, whose root holds the
files with no dc/ level (core/oslib/oslib.cpp:118-196, core/stdclass.cpp:95-125).
Without standalone_path the standalone layout of a pack fell back on path:
and put every file one directory too deep.
