This is a native port of Doom to the iPhone. There is no controller support yet, so you really can’t do anything except watch the demo scenes. WAD files go in /var/root/Media/Doom . If the app quits immediately after launch, there was probably an issue with the wad file. If you’re using the shareware wad, make sure it’s named doom1.wad . If that doesn’t help, execute the app from the shell so you can see the printf()s.

Thanks to for the news.
