To apply the crack, follow these steps:
Another option is to use the crack program of Chaos Strikes Back for X68000 which also works with Dungeon Master for X68000 (both use exactly the same copy protection scheme): You can copy CK.R into the disk image, and modify AUTOEXEC.BAT to run CK.R before running the game. The CK.R crack works by intercepting read attempts of the copy protection sector on the floppy disk and returning the expected data to the game.
