Here's the latest build of iPhone Doom, sent to us by Stephen T a.k.a. psychochromatic, who recently took over the application from stepwhite. Last night on the Talkcast we were chatting about the biggest stories of 2007, and I totally should have mentioned iPhone NES and iPhone Doom-- these were two huge projects we heard about in the early days of iPhone hacking that really set the pace for putting third-party applications on there.
Psycho says that this build is not quite playable yet, but he's got it faster than ever and working in widescreen mode. The control scheme is definitely interesting, too, although not quite as intuitive as you might hope. At any rate, steps are being made. I continue to be impressed with the potential of the iPhone in terms of gaming-- here's hoping, yet again, that the official SDK will let us do this stuff as well.
