I saw over at <a href="http://www.ngemu.com">NGEmu</a> that a new Dreamcast emulator is being worked on, though both the author and the name of the emulator hasn't been revealed yet. NGEmu has posted a screenshot of the emulator displaying the Sega logo, which is always a good start. 
Head over to <a href="http://www.ngemu.com">NGEmu</a> to have a look at the screenshot.
