NTVDMx64 is a port of the Windows NTVDM from non-x86 machines to x86_64 developed by Leecher1337. It allows 16-bit Windows applications and games to work on 64-bit Windows[1].
Overview
NTVDMx64 can run text-mode DOS applications as well as games such as Doom. It was tested on the 64-bit versions of:
- Windows Server 2003
- Windows Server 2008
- Windows 7
- Windows 8
- Windows 8.1
- Windows 10
- Windows Server 2016
- Windows 11
It is based on the NTVDM implementation in the MIPS, PowerPC, and Alpha ports of Windows NT 4 which used "SoftPC" processor emulation to provide x86 software compatibility. By porting the emulated CPU from the leaked NT 4 source code to x86_64, 16-bit applications could work on 64-bit systems.
Review
NTVDMx64 is very slow, and it uses non-standard ways to run 16-bit applications and games, so alternatives are recommended where possible.
