EXE2COM, also called E2C, is a DOS utility that converts an EXE file to a COM file that works the same. It was developed by "The Doors of Perception", also called "The DoP Timisoara".

This article is based on v1.02, the only version that has been found.

Discussion

EXE2COM rejects some EXE files, without giving a reason.

Format details

There are at least two templates that a generated file may be based on. The template is selected automatically, possibly depending on whether the EXE file has relocations. The identification string that appears near the beginning of a generated COM file contains either "E2C v1.02a" or "E2C v1.02b", depending on the template used.

The generated COM file contains a full copy of the original EXE file.

Identification

The generated files are very formulaic, and could be identified in a number of ways. They start with byte pattern be 4a 01 bf 50 fe b9 ?? ?? fc 57 f3 a5 c3.
