Dreamcast Emulators

I have collected a few emulators for the DC. I am trying to put together a total list of emulators created.

I have one for Colecovision, NES, SNES, and Genesis. I also have a so-so version of Mame, which I don't really count because my version is not fully functional.

Does anyone know of other emulators for DC? I have heard of a SMS emu, but I have yet to see it.
great place, huh
Yeah, but actually the front page is quite outdated. Lots of new/updated emus and homebrew.
