Identification

• The files start with RGMH and then this byte sequence: 4D 00 69 00 6E 00 65 00 73 00 77 00 65 00 65 00 70 00 65 00 72, which reads "Minesweeper"
• Then, the next byte sequence appears: 4D 00 69 00 6E 00 65 00 73 00 77 00 65 00 65 00 70 00 65 00 72 00 2E 00 4D 00 69 00 6E 00 65 00 53 00 77 00 65 00 65 00 70 00 65 00 72 00 53 00 61 00 76 00 65 00 2D 00 6D 00 73 which reads "Minesweeper.MineSweeperSave-ms" which is the filename always uses.
• Then, it's a PNG thumbnail, and the XML board file, which starts with: <Board> and like <SaveVersion>3</SaveVersion> which is the version used to save the game.
