Darxide EMPTM is delivered to you as a self-extracting archive executable of around 1.7MB which auto-installs when you double-click to run it. It installs an executable on your Pocket PC which will run on PDAs which: use Microsoft Pocket PC 2002 operating system or later, AND have CPU's based on ARM 32-bit RISC processor designs. The Darxide EMPTM game is NOT intended to be run on desktop or laptop PC's, only on Pocket PC PDAs which meet the above criteria. At the time of writing the majority of suitable processors used in Pocket PC PDA's are supplied by Intel using the 'StrongARM' or 'XScale' brands, although Texas Instruments' 'OMAP' processors are starting to be used by some PDA manufacturers and should also be capable of running Darxide EMPTM. Many other semiconductor vendors also have the capability to produce CPU's that will run Darxide EMPTM and may be used in Pocket PC PDAs - the key factors for compatibility with Darxide EMPTM are the ARM CPU architecture and the Pocket PC OS, not the semiconductor vendor. Microsoft currently maintains a list of PDAs and other mobile devices which run PocketPC 2002 and later at http://www.microsoft.com/mobile/pocketpc/learnmore/hardware/default.asp which contains information about the processor used in each. Darxide EMPTM has been successfully tested on a wide variety of Pocket PC's, using StrongARM and Xscale CPUs, and Pocket PC 2002 and Pocket PC 2002 Phone Edition OS. Currently we understand that Toshiba e740 Pocket PC's may run the game slowly (~13 FPS). We are not aware of any other problems.
