It doesn't have to be so complex you know. You could just do it for DOS, as a TSR, by simply creating an INT 0x40. Of course, not all features would necessarily work, but...

I thought an emulater already exists. check here http://meosfiles.narod.ru/index_eng.htm. but i think it would be more involved than just writing a single interrupt in dos.

Yeah, I'm just saying it doesn't have to be as slow, complex, or big as the one that exists. You would have to add more than that, but because DOS isn't pmode you can do whatever you want, and you don't have to do a lot more. The Windows version that exists now probably takes a lot more code than it needs, and it isn't even finished or perfect yet. I still have a lot of problems with it.

Just add the MenuetOS executable format, the mouse driver (using INT 33h) and etc. It would probably need to be unreal mode, and only one app at a time, but it's probably better than the current one...

Also, when it crashes it should at least give a decent error message as to WHY it crashed.

i know this topic is a few months old, but ive gotta say something or it'll bug me forever:

yeah - except somehow run a pmode program... This could be achieved by doing some simple pmode stuff, but if your going to 1) need plain DOS mode (you cant mess with pmode in windows) and 2) have to re-write most of the kernel anyway (GUIs need more than a mouse driver and some VGA), you might as well use the real MenuetOS.

Running the application natively would actually have the opposite effect. In an interpriting emulator (ie goes through each instruction, then does some code to emulate the instruction) you can more easily print the stack contents, registers, address of current instruction, etc. that and if proper protection isnt done in such a DOS emulator (not giving complete control to the application, catching page faults and such) the application could actually crash the emulator when it dies.

I see little point in a Dos MenuetOS emulator, athough it would take about a week to make.

Do I understand correctly:
You want MenuetOS emulator not MenuetOS *program* emulator. Because if not so, then it has existed for a very long time already - http://mikedld.org.ru/
