Keep a look out for the new TDGMods site, in development right now. It's using a CMS and should be adequate enough to replace this website. It will be content-rich and should attract even more people to the project.
While I'm here, if you're interested, please check this link out. In it, I explain the reasons we're working on this wonderful game and why it shouldn't be counted out because it uses a slightly outdated framework.
And yes, we are in prelim work on a PSP version. This version will be more faithful to the PC release as it's using the 1.31 version of the engine (in comparison, the Dreamcast is using a 1.29 fork). I wasn't going to reveal it now but I felt it was necessary to explain in the post itself.
Sleep now. Work early tomorrow. =/
