While searching through YouTube, I managed to find a video of Radiant Silvergun Homebrew version. So far, it looks like it's still in it's alpha testing, so I don't think they'll release it any time soon.
Oh, and by the way, Radiant Silvergun was probably the greatest shooter ever, and one of Sega Saturns greatest games ever to have been created.
