I almost missed this while I was in Atlanta: Apparently it is now possible to run Linux on your Dreamcast. Now, this is not for kids; you have to do some very scary things just to get it to boot, but it’s still very cool. Other than running Distributed.net, I can’t yet imagine why anyone would want to do this… but that’s not going to stop me from trying.
More good Dreamcast hacking info can be found at Dan’s DCDev.
