Well I would like to use a hybrid system where the HX Windows emulator provides "extra DPMI functionality" by emulating (some of the) known and documented Win32 API calls.

That is, A DPMI program with extensions provided by Japheths Win32 emulator.
Is that such a bad idea?

I could write a custom Delphi RTL, but that would be defeating the object because I want to write an application framework that will detect what environment it is running under (DOS/DPMI or Win32) and act accordingly. The same .exe would be able to be run either as a DPMI app or as a native Windows app. But DOS/DPMI is the deployment target because there are things that Windows can't do, such as realtime. Since limited pseudo-realtime functionality can be emulated under Windows by carefully controlling the Windows environment (during GV32 application development), it is likely to be possible to do the vast majority of GV32 application development work under Windows and the Delphi IDE and debugger, with just the final part of testing done under DOS/DPMI.
