NTVDMx64 alternatives
NTVDMx64 allows running older DOS programs on 64-bit Windows 7 and 10. It is compatible with Windows Server 2008 R2 and possibly newer versions. It integrates with Windows, enabling access to the file system and ports similar to the 32-bit NTVDM. It is slower than DOSBox or vDos but offers better integration with the operating system.
