The calls are transparent for the caller, so this shouldn't be a problem, but there are 2 different ConHost DLLs that implement 2 versions of the console server. On Windows 10 for instance, a registry entry forces the conhost to use Console V2, so this has to be changed to use V1 console so that NTVDM can interact with it, but this fortunately is just a matter of setting a registry key.

So this is all rather complex, but it sort of works with some patches to the operating system. It's enough as a proof-of-concept and to use it for most business applications and even some games. Cool, where can I get it? However I published the code and compiled versions of the loader that enables you to run the patched NTVDM, as this is my own code. As the OpenNT project released the sourcecode, copyright issues are up to them, I can just say that you need the old-src.

Depending on the build flavour you choose, you also need the appropriate SDK package. I'm providing patchfiles that patch the sourcecode to compile your own version of NTVDM which works on x64, publishing patches shouldn't be a copyright issue, I hope.

And therefore you can try to patch the source and compile it yourself. This build is left unmaintained and unchecked, so don't complain if it doesn't build anymore.

But it will probably never support graphics, as it is technically impossible to emulate a real VGA card with sufficient performance on VT-x Works with minnt and old-src build.

You must also ensure, that the machine is connected to the Internet during the first run of a DOS-Application, because the loader code needs to fetch symbols from the Microsoft Symbol server so that it can call OS internal functions in order to properly start NTVDM. When the symbols are once fetched for the current user, they won't be fetched again, until either the Temp-folder is cleared or the OS files are upgraded.

After running vdmdebug. Do not call Yoda, Yoda will call you. The PC speaker output is choppy and generally inaccurate, I want my PC speaker sound back This is not NTVDMx64's fault, it is related to a bad design change in Windows starting with Windows 7.

Please note, that detection of the key is done upon inital load of ldntvdm. This only works in graphics mode! Here is how it works: The. PIF file.
