It should work because of the emulated CPU. However graphics DOS apps won’t work, because internally the VGA emulation uses the CreateConsoleScreenBuffer with an undocumented flag that allows it to create console graphics screen buffers (so that graphics can be output in the same console window as the one which was used to launch the DOS app). This feature strangely doesn’t work on x64 versions of Windows, see here: http://blog.airesoft.co.uk/2012/10/things-ms-can-do-that-they-dont-tell-you-about-console-graphics/
A workaround would be to use the classical GUI APIs to do the job.

In reply to superpete. I would assume so.. the only way to know for sure is to try it. Although ntvdm on reactos will have hooks that I'd assume MS windows will not ...

As the CPU itself is emulated, could this be made to work in AMD64 versions of Windows?

I wonder how impossible it would be to do an OS/2 personality…..

Don’t hesitate to go to our IRC channel #reactos (on Freenode) and get in touch with the NTVDM developers!
