The problem#

Tametsi (available on Steam¹) is a great logic puzzle game that is a collection of Minesweeper puzzles that can be solved without guessing. The game consists of 100 puzzles plus 60 "bonus" puzzles. The bonus puzzles are in the game directory in an XML-based format that another player has documented well enough that they have even created some puzzles of their own and a viewer for those files. But the base 100 puzzles are nowhere to be found in the puzzle directory, and I had ideas for doing something with them.

The solution#

Given the file DumpPuzzles.java:

public class DumpPuzzles {
    public static void main(String[] args) {
        // Loading puzzles sets the graph on
        //  Game's MouseHandler, so it has to exist.
        game.Game.mh = new io.MouseHandler(null);

        for (int i = 1; i <= 111; i++) {
            puzzle.PuzzleOut.writePuzzle(
                new puzzle.Puzzle(i),
                String.format("puzzle_%03d.puz", i));
        }
    }
}

put it in the same directory as tametsi.exe² and run

$ javac -classpath tametsi.exe DumpPuzzles.java 
$ java -classpath tametsi.exe:. DumpPuzzles

Then the puzzles/ directory will be full of files named puzzle_001.puz, etc.
