That's not to say there aren't some really useful and interesting features on both websites, which, thanks to the work of programmer Jial and DreamPipe, are now available once again. The Rush 2049 website in particular offers some really cool and interesting features, including the ability to upload and download ghost times and participate in an online leaderboard for certain circuits. At the time of writing, yours truly is ranked number 1 in the world at the Marina track. As ever, autographs will be available for a nominal fee. Edit: I'm now ranked number 2, dammit. I will have my revenge!
The ChuChu Rocket! website has been restored by Xiden and similarly is hosted by DreamPipe. Sadly, there is no ability to upload scores to the ChuChu Rocket! site, however there are still some pretty cool features available, such as the ability to download puzzle stage DLC to your VMU. What's worth noting here though, is that with the resurrection of the website along with the previously restored online multiplayer modes, ChuChu Rocket! is one of several games that now has all of it's online functions fully back online.
In order to make the most of these features, you will need to sign up for a fake Sega.com account which you can do here. Because these sites are hosted by DreamPipe, the account details once stored by Sega no longer exist and it's actually a stroke of genius that the folks over there created this workaround to allow idiots like me to 'sign up' to a no longer available service once offered on Sega's main website. These two additions add to the previously restored Sonic Adventure, Sonic Adventure 2, Ecco and Jet Set Radio websites that can now be accessed direct from your Dreamcast. Bravo to everyone involved in this continued online restoration project.
