On windows, save file is in %userprofile%\appdata\locallow\RalivDev\Archipelagates\saves
Save file is in plain text, you can edit it with any text editing program. Format is json, so you can use some form of json pretty print website to make it more readable rather than all on one line, the game should be able to read the save even if you have line breaks.
