Oh? I have tried DOSBox a few times and dislike it beyond belief. I prefer booting up an older computer and just playing it that way. It may seem redudant but the software is running how it was intended.
Now, you can debate about why I'd even want to emulate an older PC game on a Wii then but it'd be about the different experience. The possibility of gameplay with the WiiMote is cool because it's not something a computer has openly offered. Also, I'm sure with the Wii's processing power it'd have no problem playing games as new as the 2000s.
