Doom for Pocket PC

Doom for Pocket PC (later retitled Doom PDA) was initially released in 2002 by developer MachineWorks Northwest, LLC, and published by Simon & Schuster Interactive, Inc, for MIPS-based devices.

The base for this port was the WAD for The Ultimate Doom, even though only the original three episodes are playable. All cheats from the DOS version work, but the level select cheat does not work for the fourth episode Thy Flesh Consumed. This port does not play any music, though the music volume setting is still shown in the options. There is no support for multiplayer games or for loading WAD files.

Digital re-release
This port was later re-released as a digital download for ARM devices as "Doom PDA." At that time, developer MachineWorks Northwest unsuccessfully pressured the authors of several free and open source ports for Windows CE devices in an attempt to make them cease distribution. This action raised the ire of many Pocket PC gaming enthusiasts.

Bugs
The game must be installed to the default path, even though the setup asks if the user wants to install it elsewhere. If it is not installed to the default path, a misleading error message pops up, stating "Serial Numbers Don't Match!"

Another issue with this version is that, after a device restore via ActiveSync or Windows Mobile Device Center, the device need to be reset immediately; otherwise, the game does not start, and the misleading error message pops up instead.
