Do you have windows pc? If yes, try to dump using same command and option by the windows version. If no, please search for the following byte sequence using binary editor or IsoBuster.

49 53 63 28

These 4 bytes indicates this file is "InstallShield Cabinet". DATA1.CAB has it, but I can't uncompress this file alone.

I don't have a Windows install, but if nothing else works then I might be able to dump the disc in a Windows VM, although at that point the host OS might somehow interfere.

grep: ./DATA1.CAB: binary file matches
grep: ./DEMOS/Pharao/_sys1.cab: binary file matches
grep: ./DEMOS/Pharao/_user1.cab: binary file matches
grep: ./DEMOS/Pharao/data1.cab: binary file matches
grep: ./_SYS1.CAB: binary file matches
grep: ./_USER1.CAB: binary file matches

These are the files with the pattern. So just the CAP files, of which probably only the ones in the root directory are relevant here.

Using unshield I was able to extract DATA1.CAB just by itself.
Would using unshield solve your problem?
If not, then what else do you require from me to continue debugging?

`SYS1.CAB` and `_USER1.CAB` seem like generic files to me. But their content differs from the Pharao demo files.

23f0395b61628f5b3698714708a5e876  DATA1.CAB
b29ebf3acc5956976b4bfc2fe9a08efa  _SYS1.CAB
b86c35678dc9462f9408a4e45d09113e  _USER1.CAB
f243222661eb930434d633e897b06d39  DEMOS/Pharao/data1.cab
cf31d5b3a38d037a28f1ada7396de627  DEMOS/Pharao/_sys1.cab
1e7003bea4ce8b9ab18839b834612ff5  DEMOS/Pharao/_user1.cab

So maybe those would help you?

Thanks. I confirmed ZEUS_subIntention.txt is correct.
