iDoom is a Doom port for the Apple iPod developed by Benjamin Eriksson, alias Hyarion and Mattias Pierre, alias Jobbe. It is built from the original Linux Doom source code that id Software released in 1997.

History

The idea to port Doom to the iPod started in September 2004 when a developer known as Edit0r started initial developments. This version was halted after two months of development due to a lack of programming knowledge. In November 2004 another developer called Aegray used Nano-X Doom, a port of Doom to Microwindows to compile for the iPod. Shortly thereafter, a working but very unoptimized version for the iPod Photo by another developer known as wCars05.

iDoom materializes

It was around this time that Benjamin Eriksson downloaded the source code to Nano-X Doom (not to be confused with NxDoom) and started tinkering. A first version of this modified port got released, but Eriksson realized it would be simpler and more efficient to start from scratch using the original Linux Doom source code. Together with Mattias Pierre, alias Jobbe, they set out to provide a fast and nice looking port for every iPod running the iPodLinux system.

The first version under the iDoom umbrella was released as version 1.0 on October 4, 2005. Version 1.1 followed a month later on November 5, introducing support for the IPod Nano 1G and iPod Color models. A bugfix release known as 1.1a followed on November 10 to restore iPod Photo support.

2006 saw the release of iDoom 1.2, being released on January 15, 2006. It supported improved menu controls, optional wheel turning via a configuration while and fixing a bug regarding loading so that iDoom now could both load and save games. A final release followed on May 18, 2006 as version 1.3. This release introduced support for the iPod 5G, also known as 5G Video. The source code of this version also was released.
