Any working Dreamcast emulators?

[Overbite]

A while ago I heard of some DC emu called "chakan" or something, and it had no compatability. Anyone know of any that can play games?

Also, are there DC--> USB adapters?

I have a ton of systems hooked to my TV and im trying to thin it out a bit, might as well emulate the ones I can.

You must mean Chankast.
