This is a parser and a disassembler for 16bit Windows target, known as New Executable (NE).

The "New Executable" format is an old format, which old 16bit Windows OSes (1.0 to 3.1x) have used and 32bit OSes have supported through emulation (WoW32).

This is different from PE (Portable Executable) or the plain MZ (DOS) format.

• NE file has the "MZ" magic at the beginning of the file
  • However, the converse doesn't hold. DOS executables and PE executables have "MZ" too.
• NE file has the "NE" magic at the beginning of the "new header", the place of which is indicated by a little endian 32-bit integer at 0x3C from the beginning of the file.
  • DOE executables lacks this "new header" and PE executables have "PE" there.

• Internet Archive publishes an archive of Windows 3.1-related softwares. Be sure to check if its legal on your country.
• Vector, a traditional Japanese software (shareware/freeware) library, has a directory of Windows 3.1 softwares.
