I found the Titles at the but he didn't post a website just the link to download it.
You can view his posts they are still there but you may have to register to do search for "Hellbound Hillbilly" to view them.
As for the Hi-Res weapons, I got those just click jDOOM on the left then scroll down a bit to see.
He can be sent a private message through the New Doom Forums but like I say you'll need to register to do that.
Let me know if you don't want the link to the New Doom Forums on here and I'll remove it if you wish.
