DOSEMU 2 has some better compatibility with some games, and some worse. For example, I was able to run DPMI TW2002, pkunzip, darklands, etc., just fine. But some games have odd issues, particularly I can remember LORD 2 behaving strangely.

At the end of the day if you want maximum compatibility with few/no issues, running 32 bit Windows is your best bet. Kind of unfortunate. :(

Yep, ntvdm runs any time I launch a DOS program. It creates some overhead but seems to work more or less fine. *shrug*
