Looks like 3D realms have finally cougthed up the source code for Duke3D - http://www.3drealms.com/index.shtml (under the shoddy 2600 April fools joke).
With a bit of luck somebody will do a decent windows port 'ala Doom Legacy. I've already managed to get it running under XP, but decent input support and some native stability would be more then welcome.
On the topic, anyone got the Plutonium Pack upgrade? I missed it at the time and I dont particularly want to buy the atomic edition budget re-release when I already own three quarters of it.
