#184334 - It's pretty much true.

The usual reason why old (sometimes not-so-old) MS-DOS/Win16/Win32 apps fail in "recent" Windoze (including XP) is usually because of the level of "virtualisation" already inherent in it - meaning that you can't directly hack with port hardware registers, etc.


In the virtual machine, you can hack directly with the registers (you can even install your favorite flavor of DOS if you find that Windows keeps you from meddling with the hardware, or ancient versions of Windows like 3.0 or 3.11). Of course, the registers you hack with won't be those of the actual hardware.

So it sounds highly unlikely to me that adding a further level of virtualisation can help anything!!


If virtualization doesn't help, you can still resort to simulating the whole PC. Modern hardware is fast enough to simulate a PC that older software can run on. The only thing that's a bit more difficult is adding non-standard hardware to the simulated PC, since this would require expanding the simulator. ;)
