The launcher's home has a Saves screen: Export Save writes NX2navi-save-<date>_<time>.zip into Downloads (or a chosen folder) with a manifest, the save the game would load next and, for a bug report, the game's latest log and nx2navi.ini, never a key file; Import a Save checks a zip's manifest, game, paths and CRCs, backs the current save up into the saves folder and replaces it while the game is not running. The game's Game tab has the same exports and an import that waits in profile/save-import and becomes the save at the next start, since the running game would write its progress back over a save replaced under it. The zip code (runtime/save_zip.c) and the import at start are checked without game files by tests/save_zip_check.py and tests/save_share_check.py; the launcher side by its test suite.
