Every launch constructs a fresh iso_archive for each ISO game, which calls iso_form_hierarchy() and walks the full directory tree. On top of that, qt_utils opens a second iso_archive just for icon loading, so every ISO game ends up doing two full directory tree walks on every launch. This adds a metadata cache keyed by ISO path + mtime stored under fs::get_config_dir()/iso_cache/. Each entry stores the raw SFO binary, resolved icon/movie/audio paths and raw icon bytes. - On cache hit, iso_archive construction is skipped entirely for both game list scanning and icon loading - On cache miss archive is scanned as before and the result is persisted to disk - Cache is automatically invalidated when the ISO file's mtime changes Tested with a decrypted PS3 disc ISO (God of War III): - First launch writes cache files correctly to iso_cache/ - Second launch reads from cache with correct title and icon - touch game.iso correctly invalidates the cache and triggers a rescan |
