Heres some great news from the Spanish Dreamcast website:

Indeed, our "beta man" Comby Laurent has kept his promise and has just released this new beta of the unreleased Half Life of Dreamcast!

This version is the 04/20/2001, with internal number 1638, it is older than the one that was already on the Internet (1672), but it is very interesting because it can contain new material that allows, for example, to make a version with online gaming and replicate mods like the Counter Strike!

Also they comment that it is the first version that is obtained in GDI, and that there are no compressions of audio nor cuts so that it fits in a CD.

The link of the download can not be published directly in the news, but you will find it quickly.
