# Records a before/after filename manifest under /storage1/igir/manifests for
# reversibility. Unmatched files are left untouched; --dir-game-subdir never
# keeps the folder flat (EmuDeck expects flat per-platform dirs).
#
# Only run on platforms that scored healthy in igir-dryrun.sh (>=~80% identified)
# AND have no co-located saves keyed to ROM basenames (renaming would orphan
# them) AND are NOT disc systems with .m3u multi-disc playlists (renaming the
# images breaks the playlists). Carts are the safe case.

#
# Undo: the before-manifest lists original names; igir is deterministic, so
# re-running against the same DAT is idempotent.
