DsDoom

DSDoom (also spelled DS Doom) is a source port for the Nintendo DS, based on PrBoom 2.4.2. It was made by TheChuckster, WinterMute, and Jefklak. The latest official version is 1.2.1. Being a homebrew application, the player must use a DS flash card in order to play it on their DS.

Features

 * All IWADs compatible with PrBoom 2.4.2 are compatible with DSDoom.
 * Both screens render at 320x200 resolution, which is then scaled down to the DS's native 256x192. This is not a feature, but a sign of a lazy as-is port of prboom to ARM with few optimizations for DS hardware.
 * 3D view runs fullscreen, without the status bar.
 * The second screen displays the automap, including the status bar.
 * The screens used for the 3D view and automap can be swapped by the user.
 * Sound effects with stereo panning.
 * Multiplayer network play using a PrBoom server and the DS's built-in Wi-Fi support.
 * Utilizes the PrBoom 2.4.2 configuration file.

Limitations and bugs

 * Certain buttons on the DS instead act as the default keyboard keys used by PrBoom. Sadly, this means that a configuration file utilizing non-standard keys can render the port completely inoperable.
 * Configuration file changes are not saved.
 * Save games can become corrupted and unusable.
 * There is no music support because this is a lazy port.
 * Crashes, while uncommon, do occur.
 * DSDoom does not make use of the DS's hardware-based 3D rendering capability due to laziness and lack of developer skill. Seriously, someone ported Quake and Quake 2 to the DS WITH multiplayer. There's no reason Doom should have any issue rendering at native resolution with music.
