John Carmack is the man behind Commander Keen, Wolfenstein 3D, Doom, and Quake. He as the lead programmer behind the games and is the co-founder of id Software. Carmack has confirmed that Doom Classic has been submitted to Apple for approval in an interview with TouchArcade.
Doom Classic will be running on the OpenGL rendered graphics engine. The sound engine will have better quality and a crafted control system. It’d be cool if the modded versions of Wolfenstein 3D make it on the App Store too such as the Barney and Beavis/Butt-head version.
