Type: Demo (DOS)
Known versions:

• v1.02: chasm.zip
• v1.28: CHASM128.rar [the files have been repacked]
• v1.32: cdemo.zip
• v2.10: chasm210.exe [packed inside a RAR archive, the self-extracting installer is possibly not original]
• v2.20: chasm-sw.zip
• v1.05: chasmdem.zip

NOTE: DOSBox CPU core emulation must be set to normal to run any version of this game.

So I tried all of the versions listed here, and they work except for the 1.28 version. In DosBox I get a message: "Bad csm.bin header." Has anyone tried to run this version and does it work?
P.S. Big thanks to MrFlibble for putting up all this information on obscure game demos.

The files were copied from a CD and are marked as read-only. Just remove the read-only file attribute and the demo will work fine.

Thanks, it's working now.

BTW, welcome to the forums!
