There is a Dreamcast binary of 0.9.9, but for whatever reason, it isn't on the downloads page on yabause.org . It is however on the sourceforge download page for the project, and can be downloaded from this link.
As for what its like, its slow, and don't expect it to run anything at any playable speed (and yes, I'm allowed to say this as the person who ported it). As for how to burn it, I probably couldn't tell you how to do it on Windows, as I haven't used it regularly in a few years...
