Connecting Online with the dreamcast using your pc!
 

I have tried it it's pretty cool,i was playing pso online it was a bit laggy beacuse i was playing and using my pc at once,you can connect online with the dc and pc at once without using the phone line, only if you have a broadband connection,P.S you don't need a broadband adapter for the dc.-->www.dcvision.com and click dc pc sever.

You understand that using your PC as a server for the DC, you're only getting 33.6 or 56kbps speeds for your DC, no matter if you have broadband or not... That also can cause a lag over what you'd get if you were using a BBA.
