When I said that dos emulators are better than windows emulators in general, I meant that the dos emulators WORK better than windows emulators. I've tested both WINE and dosbox. Almost every dos game works fine in dosbox but many windows games don't work in Wine. This fact is actually obvious because windows (with directx etc.) is much harder to emulate than dos.

WINE means "Wine is not an emulator". Maybe the word "emulate" has a specific meaning which is not true for WINE but at least WINE simulates a system. A program started under WINE doesn't "know" it's actually running on a non-windows system. That's what I call a simulation, although personally I don't differ between simulation and emulation.
