Phantom and myself have put a demo together of our homebrew Chess game, Dreamchess, that we’ve been working on over the past year or so.
It will run on the Dreamcast, as well as Windows, Linux, and BeOS.
You can get the Dreamcast version, in a ready to burn CDI image here.
If you are interested in trying it out on the PC, the source is on our Berlios project page.
Also, we are in need of 3D models, artwork, and eventually audio/music. The game already has the theme support — take a look in the data folder on the disc, or send me an email and/or message me on the forums for more information if you are interested in helping out.
