What was checked

The native 0.13.0 preservation record reports 373 automated tests passed, with no failures or skipped tests. Those checks concern the reconstructed engine and source fixtures; they do not establish a complete original-game playthrough.

What remains

The native reconstruction is incomplete. Its later rooms, combat, spells and quests, general dialogue rendering and complete audio system still need work. The original-game player runs the Japanese ROM through an emulator; it is separate from that JavaScript rebuild.

The requested free Matchbox guide is an identified enhancement in the recreation. It does not change the ROM used by the original-game player.

The next published update

Each new native release will have its own dated entry here, alongside the playable update. Earlier entries remain as a record of what was available at the time.
