Released 1993

DemoMaker (or The DemoMaker) is a DOS application that creates self-playing presentation-like documents in EXE format. It was developed by Ron Janorkar.

It can be used to document or demonstrate an arbitrary DOS program (text mode only). It allows the user to make a series of screen captures, and add text boxes to them.

A non-executable .DMK format also exists, though it is largely hidden from the user. It seems to be something like a project file.

Identification

v1.00-1.55 EXE format: The executable part is compressed with EXEPACK. A string like "DemoMaker v1.55 (C)1993,1994 R.Janorkar" appears at offset 514, though files exist in which it has been erased. There are no other obvious signatures. The first 1100+ bytes of the file might always be the same for a given version.

v2.00 EXE format: The executable part is compressed with PKLITE. There are no obvious signatures, though the corrupted PKLITE strings (at offset 30 length 52, and offset 146 length 18) might be distinctive.

DMK format: Undetermined.
