Dosbox shareware nagware version? legit? Or not?

I was chekcing out dosbox before and saw an open source dosbox (dosfreak provided a link)

Then today i typed dosbox into google today and found this.

they have a shareware "Dosbox" program with nags etc.

Is it separate product, or some kind of scam?

Hi Duhmez,
I'm almost certain that this is some other product here's a valid URL for the free application:
http://dosbox.sourceforge.net
