Crack

To apply the crack, follow these steps:

1. Open the file FTLCODE in a hexadecimal editor.
2. Go to offset 0x254BA and replace 61 1C 1E 00 61 18 B0 07 67 06 by 0C 2E 93 91 00 09 67 00 00 6A. This will remove the protection check when you start a new game. Note that the checksum (sum of byte values) of the replacement code is the same as the checksum of the original code, so that the modified file is loaded successfully by DM.X with no error message.
3. Go to offset 0x25919 and replace 56 00 00 2F 03 70 by 75 00 00 2F 03 70. Although not mandatory for the crack to work (the above change is enough), this will disable attempts to read the copy protection sector from the floppy disk, which would fail anyway when using a copied disk. However this will change the code checksum so you must also make the change below to disable the checksum verification.
4. Open the file DM.X in a hexadecimal editor. Go to offset 0xB8E and replace 67 1C 2F 3C by 60 1C 2F 3C (ignore invalid code checksum value)

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.
