Some executable files do not have the .exe extension, but they are still executable files following the DOS-MZ format (the first two bytes of such files are "MZ").
All the executable files have been compressed with LZEXE. They can be uncompressed with UNLZEXE. Once uncompressed, you can for example see the text strings in clear text in the file FIRES and dissassemble the executables.
Here is the order of execution (I'm not 100% sure of this):
For example, if you choose Mouse, Internal speaker sound and English language, the command line would be:
IBMIO FIRES -pm -si -*e
Michael Grof posted the following information in the forum explaining why there is no sound in Dungeon Master on modern sound cards:
"Few years ago, I was developing SoundBlaster emulator for AdLib Gold sound cards. DM was one of test programs I used to check correctness of the emulation. The main problem is that DM does not use any advanced feature of the sound card, it uses the card only as 'dumb' digital/analog converter. The sound code is basically the same for the speaker and for SoundBlaster - high speed system timer just feeds individual samples into the device. New versions of SoundBlasters (PCI, Live) are NOT hardware compatible with original SoundBlasters (SB2,SBPRO,SB16,SBAWE), the new cards use Ensoniq chipsets, unlike Creative Labs custom chips in old cards. So the new cards support only advanced playing techniques, and only those techniques are emulated for old cards effectively. Although designers probably tried to emulate even that ancient 'direct D/A' mode, it is surely VERY tricky and the emulation has probably terrible overhead, making the computer running like turtle once the game starts to emit samples at 10kHz rate."
