Over on Ars Technica’s Infinite Loop, Erica Sadun has a post about developer Steven Troughton-Smith who updated his port of Doom to use the iPhone’s undocumented TV-out functionality. As you can see in the photo, the iPhone itself is then used as a touch-based controller for the game, with large, easy to locate buttons. Very cool. And as for why he decided to hook it up to a monochrome Apple II monitor for this photo; “this is what passes for ‘fun’ around me.” Fair enough.
At this point Steven has no plans for adding the TV-out feature to his public build of Doom, but Erica has provided the necessary steps for you to do it yourself since the Doom source is available as an open source Google Code repository. You just need to be a registered iPhone developer, and of course know how to program.
