You can run Pocket PC software using an emulator on a Windows PC but its not a simple process. You'll need to download the Standalone Device Emulator (link below)Then you'll need to sync the emulator using through ActiveSync (for Windows XP) or the Windows Mobile Device Center on Vista. If you're using Vista read the blog post linked below.Finally - you'll need to use the Device Emulator Manager which "should" be installed with the stand alone emulator. Using the Manager you first have to "Connect" to an emulator of your choice (right click on the emulator) and then once its loaded "Cradle".From there you can install any games or programs onto the emulator.
