Ten manual slots, a quicksave, a prebattle save and rotating autosaves keep campaigns as checksummed JSON files. A save includes the random state, monthly order queue, town visit and active battle. An overwritten desktop slot retains a .bak copy.

• Linux: ~/.local/share/FortyNine/FortyNine/ (subject to XDG data configuration).
• Windows: %APPDATA%\FortyNine\FortyNine\.

These are Banner's own locations. The separate River Oath game and its saves are left alone.

F5 quicksaves, F9 quickloads, and Other opens the manual Save and Load screens. Copy JSON files elsewhere for backups. The desktop launcher accepts –load /path/to/campaign.json to import a campaign file.

Slots and settings are in this browser's local storage for the website address. Use Export save above the game to download a JSON backup; Import save restores one. A desktop save can be imported into the browser and a browser export can be loaded on the desktop, including during a town visit or battle.

Browser data can disappear if site data is cleared or private browsing ends. Export backups regularly. Different browsers, computers, hostnames and ports have separate storage. In particular games.theiguru.au and retro.theiguru.au do not share browser saves; use one address consistently, preferably retro.theiguru.au.

An import checks the checksum and campaign validity before replacing the current game. A rejected corrupt import leaves the live campaign intact. Keep backups between development releases.

The early Banner development builds used older preference/storage identifiers. Export their Banner campaign and import that JSON into this edition, or use the desktop –load option. Version 0.3.1 deliberately does not copy or clear old-name browser storage or touch River Oath's files. Saves from the separate River Oath game are not Banner campaigns.
