TV-out isn’t yet a very popular feature on smartphones, so it’s not surprising that the iPhone, of all phones, doesn’t have it. However, with a few complicated tweaks and a weekend’s worth of free time, a couple of brilliant iPhone developers have uncovered undocumented TV-out features in the iPhone’s SDK, and quickly put it to good use.
One thing that these undocumented TV-out features have made possible is what you see below. A fully-working version of Doom for iPhone shown on an external Apple II monitor. True, they could’ve likewise done it on a modern TV, with color, but it seems the iPhone developer responsible for this fancies vintage.
It only required a minor update on iPhone developer part, but he says he it’s unlikely for him to update the App Store version of his Doom app to have TV-out functionality. With that, his app would be in violation of Apple’s App Store terms, or something. In any case, there’s no mention of the iPhone officially having a TV-out feature, so it’s not likely to be permitted by Apple for release.
In any case, here it is for posterity, or wishful thinking. Depends on how you view things.
