Applies To

  • Windows CE .net 4.1


The Sigmarion III Windows CE 4.1 .net device ships only with a Japanese build of the operating system. This article discusses the availability of a Windows CE Multi-language User Interface (MUI) enhancement pack for the Sigmarion which regenerates the UI into an English language system.


More Info

The MUI Interface Pack has been created by the Sigmarion III user community and is packaged and distributed from HPC:Factor. The update, unlike contemporary methods, makes use of Windows CE's Multilingual Resource Library capabilities, rather than attempting to replace ROM components in RAM.

The MUI specifically addresses:

  • Windows CE Shell & System Dialogues
  • Windows Explorer iconography & names
  • Storage Card / Mass Storage names
  • Populates the desktop with icons
  • Regenerates the yen symbol (¥) with backslash in addresses
  • Adjusts the Internet Explorer Language Code to EN-US
  • Removes the Japanese IME
System Requirements

The MUI Interface Pack requires:

  • Microsoft ActiveSync 3.5 or higher
  • 2MB of available system RAM (in Main Memory)
