How to play FM-Towns games under Windows? (Dungeon Master, Chaos Strikes Back and Dungeon Master II)

What is an FM-Towns? Check the Wikipedia article about FM-Towns.

Follow these instructions:

  1. Download Dungeon Master for FM-Towns, Chaos Strikes Back for FM-Towns or Dungeon Master II for FM-Towns.
  2. Download this FM-Towns emulator for Windows from its official web site: UNZ.
  3. Download the FM-Towns BIOS from the FM-Towns Emulators & System Files at the Japanese Computer Emulation Centre.
  4. Decompress UNZ, the BIOS files and the game in the same folder on your hard drive.
  5. You have two ways to play the game with UNZ: you can burn the CD image to a CD-R or CD-RW and play the game from your real CD-ROM drive, or you can use DAEMON Tools (recommended method), which is a CD-ROM emulator for Windows. This free utility will create a virtual CD-ROM drive in which you will be able to "insert" a CD image (many formats supported). Using this tool, you can try the game without having to burn a real CD.
  6. If you use Daemon Tools, do not forget to check "Analog audio" in the options if you want to hear the CD-Audio music tracks.
  7. Once you inserted the CD in your CD-ROM drive (either real or virtual), Run "unz.exe".
  8. Wait for the configuration dialog box to appear. In the CD-ROM1 tab, select the type of CD-ROM of emulation for your system (ASPI for Win 9x/Me and IOCTRL for Windows 2000/XP). Then configure the CD-ROM drive to use, either in the list or by its drive letter. Then click on OK. This will close the program.
    Note: I had to manually configure the CD-ROM in the unz.ini file because the settings I made in the dialog box were not saved correctly. In the CD-ROM1 tab, select ASPI and click the "Scan available devices" button. The three numbers to the left (like 1:2:1) correspond to these settings in the [CDROM Emulation] section of the unz.ini file: AdapterID:ScsiID:Lun.
  9. Run "unz.exe" again.
  10. You need a floppy disk image to save your game. In the Drive0 menu, select "Insert...". Type a floppy disk image name like "DungeonMasterSave.bin". Click Open and confirm the creation of the file. Choose the "2DD/720KB" type of floppy disk, check the "MS-DOS" checkbox and then click OK.
  11. The emulator boots on the CD-ROM. Two icons to run the game appear. The one on the left runs the game in Japanese, the one on the right runs the game in English. Press "F12" to capture / release the mouse cursor during emulation.
